The invention relates to the field of theoretical physics and is intended to generate energy, where the processes of interaction of static saturating magnetic field of permanent magnets from moving in this field ferromagnetic substance having the property of magnetic viscosity.

Magnetism is a special form of interaction of electric currents and magnets (bodies with magnetic moment) between itself and one of the magnets with other magnetic materials. Magnetic interaction between spatially separated bodies through the magnetic field H, which, as the electric field E, which is a manifestation of the electromagnetic motion form of matter. Between the magnetic and electric fields is not complete symmetry, as sources of electric fields are electric charges and magnetic charges of the monopoles are not found, although theory predicts their existence. The source of the magnetic field of a moving electric charge, electric current flows. At the atomic scale motion of electrons and protons creates orbital microcurrents associated with the portable motion of these particles in the atoms or atomic nuclei, in addition, the presence of microparticles spin leads to the existence they spin magnetic moment.

As electrons, protons and neutrons that make up atomic the kernel atoms, molecules and all macrobodies (gases, liquids, crystalline and amorphous solids)that have their own magnetic moment, then, in principle, all substances subject to the influence of the magnetic field are magnetic, they are magnets. Magnetic materials are classified as diamagnetic, paramagnetic and ferromagnetic. The latter have the highest magnetic susceptibility and are used in the technique as an effective magnets. They atomic magnetic moments spontaneously collinearly swiveling to form abnormally large magnetic moments. The best modern magnetic materials and energy work (N)maxreaches 320 T·kA/m (40 million GS·e), for example, a material with a high coercive force SmCo3(see, e.g., Transfiguration A.A., Bichard EVGENIY Magnetic materials and elements, 3 ed., M, 1986; Fevralia IE, hard magnetic materials and permanent magnets. K., 1969; Permanent magnets. Handbook, M., 1971).

The complexity of the atomic structure of substances, built of huge numbers of microparticles, offers an almost inexhaustible variety of their magnetic properties, the link with the non-magnetic properties (electrical, mechanical, optical and other) allows the study of magnetic properties to obtain information about the internal structure and the other the properties of the microparticles and macrobodies. Note that the magnets have the internal energy. In the case of a uniform magnetic field in the volume of the magnet stored energy V of the magnetic field W˜μ0H2V/2, where μ0=1,256·10-6G/m is the absolute magnetic permeability. This quantity of energy consumed almost force interactions with other magnetic materials and is maintained by the constant movement of the charged particulate matter.

The energy source is the very substance of magnets having stock of magnetic energy, which is due to processes occurring at the micro level (atoms and molecules), continuously replenished, but rather, is maintained at a constant level, except for the factors leading to the so-called aging of the magnets. In addition, the mechanical energy occurs in the process of movement ferromagnetism substances in spatially localized saturating magnetic field.

A well-known principle of entropy and the first and second law of thermodynamics operate with power transformations, which are always (except balance) are consuming energy when performing any work, the greater is the very work done, and some energy is irreversibly converted into heat. Therefore, the efficiency of all known the power converters is always less than unity. However, in microcosm has a different process: the movement of particles due to thermal energy - momentum p of the movement of particles of mass m1is defined aswhere k is Boltzmann's constant,- is the temperature in Kelvin, and the collision of particles between a cause thermal processes - heated environment, that is self-replicating exchange of energy, which is pointless to talk about heat loss, since thermal energy is the source of motion of microparticles, and the movement itself generates heat. Thus, at the micro level of reciprocal processes of energy conversion, such as thermal and kinetic occur with efficiency equal to one, i.e. are self-sustaining continuously in time. This is reflected in the "eternal" existence of matter in its different forms and types, consisting of a mass of particles - atoms and molecules are in constant motion and interaction, both among themselves and with various external fields and forces. On the other hand, at the macro level, on a cosmic scale we can say the same resistant "eternal" existence of the Universe, in which there are processes of energy conversion, however, does not lead to thermodynamic equilibrium and so the so-called "heat death" of the Universe.

These circumstances suggest that there must be a way costless energy that would be consistent with the principle of reduction of entropy. So, in the work of the author [1], it was shown that the detection of the phenomenon of corporately will be possible to transmit electromagnetic field energy from the colder body to a more hot that it is impossible according to modern concepts of thermodynamics.

For ferromagnets, obeying the Curie law, there is the so-called critical temperature Θat which the magnetic susceptibility is comparable to the unit or even becomes smaller than unity, and the substance becomes paramagnetic diamagnetic (the Curie-Weiss law), i.e. the magnetic susceptibility depends on various factors such as temperature, magnetic - eld strength, mechanical stress, and some others.

One of the interesting properties of ferromagnetic materials is the so-called magnetic viscosity, magnetic aftereffect is a time lag of magnetization of a ferromagnet from changes in magnetic field strength. In the most simple cases, the change of the magnetization ΔJ depending on time t is described by the formula

where J0and J-9with up to several tens of hours. In the General case, to describe the process aftereffect of the same value τ not enough.

There are two types of magnetic viscosity: diffusion (Richter) and thermofluctuation (jordanovski). The first magnetic viscosity is determined by the diffusion of impurity atoms or defects in the crystal structure. Explain the role of impurities was given J.Snock, and more rigorous theory built L.Neel and is based on the assumption that preferential diffusion of impurity atoms in the interatomic spacing of the crystal, which in a certain way is oriented relative to the direction of spontaneous magnetization. This creates a local induced anisotropy, leading to stabilization of the domain structure. So after changing magnetic field a new domain structure is not established immediately, but after diffuse redistribution of impurities, and possibly taking into account the effect of BA is chousen (abrupt change in the magnetization of ferromagnets under constantly changing environmental conditions, for example the magnetic field)that is the cause of magnetic viscosity.

The second type of magnetic viscosity is more versatile and is observed in almost all ferromagnets, especially in the field of magnetic fields comparable to the coercive force. Neelam was proposed thermofluctuation mechanism to explain this type of magnetic viscosity. Thermal fluctuations contribute to overcoming the domain wall energy barriers in magnetic fields smaller than the critical field. In vysokokoertsitivnye alloys, consisting of a single domain areas, there is a particularly large magnetic viscosity, as in this case, thermal fluctuations reported additional energy for irreversible rotation of the spontaneous magnetization of those particles, the potential energy in an external magnetic field is insufficient for the magnetization reversal.

In addition to these basic mechanisms of magnetic viscosity, and there are others. For example, in some ferrites contribution of the magnetic viscosity gives the redistribution of electron density (diffusion of electrons between ions of different valency). Magnetic viscosity is closely related to such phenomena in ferromagnets, as losses on alternating magnetization, a temporary decline in the relative magnetic permeability μ and its frequency dependence (see, e.g., Kronmüller H., Nachwirkung in Ferromagnetika, 1068; C.B. is osowski, Magnetism, M., 1971; DIY. Magnetic materials, M., 1981).

Known property of the magnetic viscosity of ferromagnetic materials used in the claimed technical solution.

The inventive method of producing energy has no analogues.

The inventive method of obtaining energy is that they form a gap space L saturating magnetic field for ferromagnetism substances that promote in the specified amount of space with a certain velocity V, the value of which will agree with the time constant τ magnetic viscosity ferromagnetism substances, for example, by the formula L/V≈2,8 τresulting in receive mechanical energy due to the force applied to ferromagnetically substance from saturating magnetic field and directed collinear with the velocity vector V.

The inventive method is explained by a decrease with a time lag of the magnetic susceptibility moving ferromagnetism substances placed in the saturating magnetic field, causing the retractor ferromagnetism substance power from saturating magnetic field is greater than the braking force of the substance of the magnetic field at the output of the period of interaction. Integration of the partial forces pull and braking differential volume dV Fe is romanticeskogo substances, in the period of his active interaction with the magnetic field along the length of the magnetic gap determines the resultant force applied to interacting with the magnetic field ferromagnetically substance directed along the velocity vector V.

As the closest analogue (prototype) the claimed technical solution is the device that implements the inventive method is "magnetic-viscous pendulum", known from the application of the same author No. 2005111823/28 (013701) from 20.04.2005, which is issued by the Russian patent for invention №2291546 (published in Bulletin No. 1, dated 10.01.2007). Examination carried out at the Department of measurement technology and instrumentation FIPS.

The device prototype used a permanent magnet with a saturating magnetic field to the ferromagnetic body of the magnetic-viscous material suspended on a spring and performs an oscillatory motion relative to the magnetic gap of a permanent magnet and a permanent relaxation of the magnetic viscosity of the body of a ferromagnetic material selected commensurate with the time ferromagnetic body in a saturating magnetic field, for example, with one tenth of the period of free oscillations of the body. Bringing external forces ferromagnetic pendulum is set in motion further oscillation of the pendulum continues indefinitely with defined amplitude and is astotal without influence of external forces. This raises the kinetic energy of the pendulum is the result of the interaction of the saturating magnetic field of a permanent magnet and a moving ferromagnetism substances (see figure 3 and 4).

A disadvantage of the known device is relatively small energy efficiency due to nizkochastotnogo mechanical vibrations.

This disadvantage is eliminated in the proposed technical solution.

The aim of the invention is to increase the kinetic energy derived from the interaction between a moving ferromagnetism substances with a saturating magnetic field.

This goal is achieved by collectively implement the inventive method of obtaining energy devices using the principle of rotation of the magnetic disk with the axis of rotation, is made of magnetic-viscous substances, the edge of which is placed in a saturating magnetic field of the permanent magnet (free power supply) at some period of interaction. Construction of such devices is significant diversity, in particular, performance profiles of magnetic systems and their quantity in a single device. The following is a basic model of the proposed technical solution is the device and its various modifications.

Device containing a permanent magnet and maintains deistvuushie with him ferromagnetism substance, characterized in that ferromagnetism substance made in the form of a disk of radius R associated with the axis of rotation, the edge of the disc placed in localized in space length L tangent to the disk saturating magnetic field of the permanent magnet, with the launch of the device implemented with a single application to the disk sufficient to start the device of angular momentum from an external source, and the time constant of the magnetic viscosity τ ferromagnetism substance selected from the condition τ=0,36L/ω0R ω0- is the angular velocity of the disk, corresponding to the maximum torque.

The goal of the claimed technical solution is achieved by replacement" oscillatory motion of a certain mass of a ferromagnetic body on its rotational movement and is the result of the lag in the dynamics of rotational motion ferromagnetism disk magnetic "center of gravity" is placed in the field of the permanent magnet part ferromagnetism disk in each arbitrary point in time from the center of the attraction of a permanent magnet that generates a tangential force of gravity from a permanent magnet attached to the outer part of the magnetic disk, causing a rotational moment, which supports the rotary motion of the Fe is romanticeskogo disk angular velocity, defined constant relaxation of magnetic viscosity ferromagnetism substances disk. In the case of a uniform magnetic field in the gap between the poles of the permanent magnet is implemented so-called "hard mode" excitation of rotational motion, in which you must force (under the action of external forces) to lead ferromagnetiske drive into rotary movement with the desired angular velocity. As specified angular velocity of the magnetic "center of gravity" part ferromagnetism disk associated with the magnetic field of the permanent magnet is offset from the center of the gravitational field of a permanent magnet and the amount of displacement between the centers defines a permanent rotational moment, balancing the magnitude of the friction torque (load torque) in the disk axis. The magnetic gap of the "center of gravity" of the above part ferromagnetism drive from the centre of gravity of the magnetic field of the permanent magnet is determined by the magnetic viscosity at which the differential amounts specified part ferromagnetism disk, a longer time in the saturating magnetic field of the permanent magnet, in a greater degree reduces its magnetic susceptibility than the differential volume, the magnetic saturation have no respect for our the lo. This creates a redistribution in the specified part ferromagnetism drive values of the magnetic susceptibility, the gradient of which is directed opposite to the vector acting on ferromagnetiske drive force from the magnetic field of the permanent magnet. In this system, the magnetic field of the permanent magnet is static, and the role of temporal changes in the tangential direction (known as the condition of motion [2]) perform regional sites ferromagnetism disk with variable parameters of the magnetic susceptibility, that is, the system is parametric generator rotational motion. Replacement oscillatory motion ferromagnetically mass on its rotational movement of the claimed technical solution is energetically more efficient, as it is possible to use relatively fast rotation of this mass, thereby increasing the kinetic energy of the latter.

The claimed technical solution (method and implement it the device will be clear from the submitted drawings.

Figure 1 presents a graph of magnetic induction In the ferromagnet on the intensity H of the external magnetic field at some value which occurs in ferromagnetic saturation (this chart this section of the saturating magnetic field corresponds to the range of intensities 200-30 OE).

Figure 2 summarizes related to figure 1 a graph of the dependence of the magnetic susceptibility χ ferromagnet on the intensity of the N applied magnetic field. It is seen that when N=0 the magnetic susceptibility is relatively small and has a finite value. With increasing field strength, it also increases to the maximum value (when N*=100 e), and then drops again and can have a very small value (this is the so-called curve Stoletov).

Figure 3 shows a diagram of the device-prototype - magnetic-viscous pendulum containing a permanent magnet with its poles 1 and 2, between which is placed the sample ferromagnetism substances 3 on the moving axis 4 that specifies one degree of freedom for movement of the sample 3, is suspended on the spring 5, the other end of which is connected with a stationary permanent magnet, and the slide axis 4 is in the sleeve 6 and 7 with low friction.

Figure 4 graphically presents the harmonic oscillatory motion ferromagnetism sample 3 (figure 3) - spring pendulum and the force on the sample by the magnetic field of the permanent magnet. It is seen that the effect of magnetic viscosity of ferromagnetic reduces the braking force goes by the inertia of the magnetic gap of the sample and increases the power of his involvement in the magnetic gap at reverse motion of the sample in each paragraph is superide of its oscillations. Braking force has a maximum of less than the maximum power draw due to the decrease of the magnetic susceptibility of a ferromagnet, while he is in the saturating magnetic field, and by increasing the magnitude of the magnetic susceptibility of a ferromagnet, while he moves in free space to the upper or to the lower dead points in the respective half cycles of the oscillation.

Figure 5 shows the device in a simplified form, consisting of a rotating ferromagnetism disk 8 with the axis of rotation 9 and the permanent magnet 10 with the poles 11 and 12 forming the magnetic gap, in which is entered the edge of the disk 8. The magnetic field in the gap in its certain part selected for saturating ferromagnetism substances disk 8.

Figure 6 shows the base model ferromagnetism engine containing ferromagnetiske disk 8 with the axis of rotation 9, placed in the magnetic field of the stator 10 of the four-pole pairs 11 (12) (their number can be arbitrary), the clearances are lying in one plane, placed the edge of the disc 8. Specified geometrical parameters of pole pairs 11 (12) and drive 8 indicated the direction and magnitude of angular velocity of rotation of the disk 8.

7 given scan of the stator 10 of the magnetic system in the notation of the basic device model (6) is placed in the gap of the pole pairs 11 (12) kromko the disk 8 of ferromagnetism matter and indicated the direction of movement of the latter.

On Fig shows a graph of the instantaneous (at any arbitrary point in time) distribution of magnetic susceptibility ferromagnetism substances edge of the disc in the saturating magnetic field of the gap and at its edges with optimal movement of the substance along the magnetic gap, caused by the rotation of the disk. In the work zone length L of the magnetic gap saturating magnetic field leads to an exponential decrease of the magnetic susceptibility, and the exit gap of the magnetic susceptibility of the newly restored exponentially, aspiring to the value corresponding to the current out of the magnetic gap of the magnetic field.

Figure 9 shows the scan component of the stator ferromagnetism engine (without disk). The main component of such a stator is pole pair, creating a saturating magnetic field in ferromagnetism the substance of the disk 300 e in figure 2) and have a minimum height clearance. Another component of such a stator is the pole pair with a large gap, creating a magnetic field that corresponds to the maximum of the magnetic susceptibility ferromagnetism substances (100 e in figure 2).

Figure 10 presents a plot of magnetic field strength in the respective magnetic gaps of two-component motor stator, considered the CSO figure 9 (figure 2 have H max=300 UH, N*=100 E).

Figure 11 Dan graph showing the distribution of the magnetic susceptibility along the x coordinate of the sweep component of the stator (Fig.9), the corresponding plot of the magnetic field in the gap of such a stator (figure 10) for the case of a fixed disk. Distance δx reflect the range of edge effects saturating magnetic field.

On Fig presents the distribution of the relative magnetic susceptibility ferromagnetism substances in the dynamics of rotation of the disk with quasi-optimal angular velocity ω=ω0=0,36L/Rτ relative to the magnetic gap with the saturating magnetic field Hmax. It is seen that the recovery of the magnetic susceptibility on the output ferromagnetism substance from a gap fast enough, because according to (1) process recovery specified value χmaxcorresponding to the maximum of the magnetic susceptibility (when N*=100 e in figure 2), which increases the magnitude of the pulse braking disk.

On Fig shows the weight function G(x), taking values from +1 to -1 when calculating forces pull and braking ferromagnetism drive magnetic field in the dynamics of its rotation. This function shows that the center of the magnetic attraction of the magnetic pole pairs (for a homogeneous magnetic field, this center is in the middle of the lengths L of the magnetic gap) it does not exert influence along the direction of motion ferromagnetism substance on the element of its volume, located in the center of magnetic attraction.

On Fig presents scan design three stator of the motor (without disk), which is different from the two-component structure (Fig.9) after the introduction of the working gap with the saturating magnetic field of the pole pairs of the inclined planes, within which is formed by growing an inhomogeneous magnetic field on the coordinate X. This allows to significantly weaken the braking torque of the drive because of magnetic susceptibility ferromagnetism material out of the gap with the saturating magnetic field tends to less maximum equal to χ(Hmin)<χmax(N*).

On Fig given distribution of relative magnetic susceptibility χ(x)/χmaxthe x coordinate inside the gap with the saturating magnetic field and beyond for three stator (Fig). It is seen that when using a three-component structure of the stator is reduced a factor of the braking disk.

On Fig presents a modified structure of the stator (scan), corresponding to its three-part structure, and forming a nonuniform magnetic field, from which small quantities of tension Nminexponentially increases to N* and next to Hmaxand within N*<H≤Nmaxbecomes saturating spatzennest L along the axis X.

On Fig given distribution χ(x)/χmaxwhen performing a stator according to the scheme Fig, which shows that the curve χ(x) has a smoother and maximum efficiency criterion relations retracting forces and braking. Since the magnetic field in the working area is not uniform, then the position of the magnetic center of gravity shifted to the right along the x axis relative to the center of the length L (shown by a dotted line in the shaded rectangle).

On Fig, 12 and 17 of the angular velocity of the disk rotation ω, its radius R, the length of the magnetic gap L and the time constant of the magnetic viscosity τ bound value τ=0,40L/ωR specifies quasimaximum torque ferromagnetism engine for the given parameters χmax(H*), χmin(Hmax), HminNmaxand the number n of pole pairs of the stator of the engine.

On pig presents: family relative values of the forces acting on volume elements dV ferromagnetism substances in the gap of a permanent magnet with a saturating magnetic field, and the characteristic of Muoptimized ferromagnetism motor connected to various loads from idle to critical. These load characteristics - the essence of direct drawn from the origin at different angles to the axis of the abscissa ω the Point of intersection of the curve M uwith direct load determines the steady state of the system when the angular speed of rotation ferromagnetism disk ωslave0=L/2,806 Rτ. In particular, when the angular velocity ωaboutthe rotation of the disk at which the maximum torque of Momu.

Consider the essence of the proposed technical solution.

From the General theory of the creation of the generating systems it is known that generation is the construction of a quadrupole with negative resistance, for example, as is the case in the generator on the tunnel diode current-voltage characteristic in which the working area is a drop in the current with increasing applied to the diode voltage. The role of such a "negative resistance" in this technical solution does ferromagnet with its magnetic saturation. The dependence of the magnetic induction In the magnetic field strength H (figure 1) is characterized by variable slope dB/dH˜χ(H) (2) and in the region of the saturation curve χ(H) has a decay of the magnetic susceptibility of a ferromagnet with the increase of tension that is dχ(H)/dH<0. This allows you to create unbalanced by the force on a ferromagnetic substance by saturating magnetic field system on the basis of compliance with two conditions: a ferromagnetic substance should have with what Euston magnetic viscosity and move in the saturating field at a certain speed, consistent with the time constant of the magnetic viscosity. Consider how these two conditions allow continuous rotation ferromagnetism disk, the edge of which is placed in a saturating magnetic field of a permanent magnet (figure 5 and 6). In the basic model of the claimed device (6) pole pair 4 of the permanent magnet of the stator 3 of the engine, schematically presented in Fig.7, creates its length L homogeneous saturating magnetic field. The movement in this field ferromagnetism substances (edges disk 1) with velocity V=ωR ω - the angular velocity of the disk, R is its radius (up to the middle part of the edge of the disk), leads to the distribution of magnetic susceptibility χ(x) at any arbitrary point in time, as represented in Fig. This distribution of the coordinate x along the length L of the pole pair with the combination of the start coordinates with the magnetic center of gravity, the position of which in the homogeneous magnetic field coincides with the center pole pairs, i.e. at a distance L/2 from the edges of the pole pairs is due to the fact that part of the magnetic gap, the mass of ferromagnetic material under the action of the saturating magnetic field Hmax>N* decreases its magnetization J(t) by the exponential law according to (1), i.e. exponential law will change magnetic susceptibility < (t)=J(t)/μaboutN ferromagnetic taking into account the time constant τ magnetic viscosity according to the law:

where χ(Hmax)- magnetic susceptibility in the saturating magnetic field intensity Hmaxin the steady state (for a long period of time), Δχ=χmaxmin- change of the magnetic susceptibility for a period of time Δt=L/V. When this χmaxcorresponds to the magnetic field strength H*, a χmin- field intensity Hmaxand the connection isfrom which it follows that during the Δt=L/V value of the magnetic susceptibility χmin(Δt)>χ(Hmax).

The center of the magnetic attraction of the magnetic pole pairs (Fig) of the ferromagnet at the origin x=0 separates in the magnetic field of this pole pairs of the edge of the disc from ferromagnetism substances into two parts - retractable in a magnetic gap in the interval - L/2≤x≤0 and the braking disk part between 0≤x≤+L/2. Since the force is proportional to the magnetic susceptibility χ(x), ensuring maximum torque of the drive requires an estimation of the speed of its rotation ωaboutin the magnetic gap from equation (excluding the weight function G(x)):

where t=x/ωaboutR. the Solution of the equation (3) has the form Δt/τ=2 ln(Δt/τ+1), where we find the desired attitude Δt/τ=2,513 where Δt=L/ωaboutR. In this case, asking at x=-L/2 value χ(-L/2)/χmax=1, we get at x=0 against χ(0)/χmax=0,285, and at x=L/2, it is χ(+L/2)/χmax=of 0.081. Given the function G(x) as a factor in (3) before a member of exp(-t/τ) the optimal value of the ratio of Δt/τ is defined as Δt/τ=2,8059 (obtained from a variational calculation on a PC using Excel without taking into account the edge effects on the intervals δx Fig and 13).

After the release of ferromagnetism substances from the magnetic gap of the pole pairs of magnetic susceptibility χ again begins to increase exponentially, trying to size χ(N)corresponding to the magnetic field H(x) when x>L/2, which is substantially less than the Hmax.

The distance between adjacent pole pairs 11 (12) of the stator 10 (6) is that in this way magnetic susceptibility will be completely restored (i.e. increase) to the level corresponding to the value of χ(-L/2)so that the interaction ferromagnetism disk with a saturating magnetic field Hmaxin this next in the direction of rotation of the magnetic disk 8 pair will again repeat the above algorithm is. However, the efficiency of the engine (power) is proportional to the number n used in the pole pairs.

The increased size Δχ appropriate and is provided, if the magnetic field strength at the entrance of the magnetic gap at x≤-L/2 (Fig) is equal to N*, at which the maximum magnetic susceptibility (χmax). This condition is satisfied in a modified two-component device of a motor stator, a scan of which is shown in Fig.9. In the working gap of length L is valid magnetic field intensity Hmaxand in the adjacent magnetic gaps with tension N*. Plot strength distribution shown in figure 10. At distances from the edges of the working gap are additional magnetic field (marginal effects), which are taken into account when calculating force effects on ferromagnetiske disk, figure 10 magnetic field inhomogeneity in between δx is specified in the form of angled lines (although the distribution of these intervals is actually non-linear).

Figure 11 shows the static distribution of the magnetic susceptibility of the edge of the disk around the circumference of the motor stator (figure 9), when the disk is stationary. It is absolutely clear that acting on the drive forces mutually cancel each other and no motion of the disk with the stationary state can not be.

For the analysis of the current at the edge of the disc tangential forces (pulling and braking) when interacting ferromagnetism disk with pole pair length L (Fig) it should be borne in mind, in the center of attraction pole pair (x=0) there is no force on the ferromagnetic element with the instantaneous coordinate x=0 and increases towards the edges of the gap, as indicated by Fig taking into account edge effects. Therefore, the resultant of the tangential force ΔFΣis determined by the integration works χ(x) G(x), where the function G(x) varies in the range +1≥G(x)≥-1, as shown on Fig. Therefore, the force ΔFΣproportional to the expression:

where s is the cross section of the edge of the magnetic disk in the magnetic gap (dV=s dx).

From the expression (4) implies that optimizing energy performance ferromagnetism engine requires consideration of edge effects on segments δx and is achieved by reducing the magnetic field strength in the range x≥L/2 to a value of Nmin. The latter is provided in the structure of the three stator, a scan of which is shown in Fig. When the output ferromagnetism substances from the working gap it falls in a magnetic field with a minimum strength Hmintherefore , magnetic susceptibility in time grows slowly, as indicated on Fig, then gradually increases to a value of N*, remaining constant until the next in the direction of rotation of the disk working gap.

One possible mo is the changes three stator (Fig) may be the execution profile of the magnetic poles of the latter by the scheme, specified on Fig. This allows smooth transitions in the distribution of magnetic susceptibility, as is evident from Fig, and additionally increase energy devices. Since the magnetic field in this exponential gap is nonuniform, the magnetic center of gravity in the working area of the saturating magnetic field of length L is a linear approximation of the distribution of magnetic field strength on the length L of the formulawhere α=Nmax/Nmin*, Nmin* the magnetic field strength at the beginning of the saturation zone length L. From this formula shows that when a uniform magnetic field, i.e. when α=1, we obtain for the position of the magnetic center of gravity Xabout=0,5 L, where the value of Xaboutmeasured from the beginning of the working magnetic gap length L. the Calculation of power characteristics in a non-uniform magnetic field in the working gap is similar to that previously specified with the shift of the magnetic center of gravity from the position of L/2 on the value of Xabout- L/2 to the end of the working gap.

Torque ferromagnetism drive Muis determined by the product of the tangential force ΔFΣon the active disk radius R and the number of pole pairs n in the engine, and the engine is determined by the product of the moment Muon the corner MSE of the awn ω the rotation of the disk:

On Fig represented by curve Muthe maximum frequency ωaboutwhose value is given weight function G(x) is equal to:

The fact that the engine according to (5) characterized by non-monotonic function, is simple: at low frequency ω very fast determination of the magnetic susceptibility in the initial area of the working gap, while at high frequency ω (compared to ω0), on the contrary, the length of the gap L magnetic susceptibility does not have time to significantly decrease. In both cases, decreases the magnitude of the force ΔFΣ(rotational moment). When stopped, the drive force ΔFΣ=0, but d Mu/d ω>0, that is, the slope is Mu(ω) when ω=0 with the x-axis maximum, which explains the impossibility of samorazrusheniya drive motor of the stationary state. This is the so-called hard self-excitation mode: the start-up operation of the engine is carried out by external impact - unwinding drive to a certain angular velocity ωstart0where dMu/dω<0 at the point of intersection of the curve Mu(ω) with direct load, the slope of which is proportional to the Miu moments of friction and load on frequency ω steady-state rotation of the disk.

On Fig given family of relative forces acting on volume elements dV=s dx ferromagnetism substance in the magnetic gap for different values Δt/τand curve Muand different load characteristics - idle workload (dash-dotted line) and critical loads, which are inclined straight lines emanating from the origin at different angles to the x-axis. The greater the load on the motor axis, the steeper load direct. The point of intersection of the curve Muwith direct load corresponds to a stable equilibrium at a frequency of ωslavelying in the angular range of rotation speeds ω0slavemax. From theory of feedback systems it is known that the equilibrium is stable if the amplitude characteristic of the equivalent four-terminal network at the point of intersection with direct feedback has the opposite sign of the derivative the derivative of a line feedback. The point of intersection of the specified curve and a straight line, in which derivatives have the same sign, are points of unstable equilibrium. Frequency deviation ω to the left of these points leads to the cessation of engine operation, and the right to establish speed up often the s ω slave. If the axle load of the engine is missing, the engine operates in the so-called idle mode. The speed of rotation is increased to values ωmax. Therefore, the effect of variable load leads to variations in the angular velocity of rotation ferromagnetism disk, if the load does not exceed the maximum allowable, and if the engine was put into operation by an external impact. To facilitate starting the engine, it is desirable to implement in the idle mode and the angular velocity of rotation of the disk at start-up should not exceed the value of the angular velocity ω0.

The inventive method of obtaining energy and its various implementations are in scientific terms a new direction in energy. The physical nature of the phenomena underlying the actions of such systems, subject to research physicists-theorists in the field of magnetism and structure of ferromagnetic substance having magnetic viscosity and property to reduce its magnetic susceptibility in the saturating magnetic field.

As one of the possible scientific hypotheses to explain the physical nature of the so-called magnetodynamics ferromagnetism effect is the occurrence of displacement currents in ferromagnetism dielectric while moving in a magnetic field. Values of the bias current in the given differential layer of a ferromagnetic ceteris paribus proportional to the magnetic susceptibility χ (x) this differential layer dx. These bias currents are orthogonal to the vectors of the magnetic field and the velocity of the ferromagnet, therefore, determine the occurrence of partial mechanical forces, the vector which coincides with the velocity vector of the movement of the ferromagnet in the first half of the magnetic gap and oppositely directed velocity vector in the other half of the magnetic gap. The algebraic sum of all the partial forces produces a resultant force applied constantly to ferromagnetically substance and determining the nature of the motion of the latter. Magnetic viscosity of ferromagnetic and thus determines the rate of participation molecules ferromagnetism substances in the process of electric polarization of the molecules from their total number in a unit volume of a substance dV(x).

Another physical model of this effect can be Zeeman splitting of the unperturbed energy States of molecules ferromagnetism substances in the saturating magnetic field energy conversion Zeeman transitions into mechanical energy, whose probability is proportional to the current value of the magnetic susceptibility χ(x) ferromagnetism matter on the length of the magnetic gap 0≤x≤L. the Process of energy conversion is carried out on the site dχ(x)/dH(x)<0, when Fe is romanticeskoe substance moves within the magnetic gap during the time Δ t, that is, if dχ(t)/dt<0, where 0≤t≤Δt=L/ωR.

Both of the proposed research hypotheses require more detailed development physicists-theorists, perhaps on the basis of quantum electrodynamics.
