The invention relates to the field of electrical engineering and is intended to generate electricity fuel-free, harmless and economical way.

Closest to the invention is a method of obtaining electricity antrotomy unit proposed Kasparov M. and Simonov CENTURIES in 1950, consists in the fact that the rotor and contractor (stator) of the generator rotate coaxially with the turbine in different directions, it achieves greater frequency of rotation of the rotor relative to contrator that allows you to increase capacity, reduce the number of poles of the generator, hence its dimensions and weight (Simonov VV Flow hydraulic turbine of high and ultra-high speed. M.-L.: Gosenergoizdat, 1951).

The disadvantage of the above method is that when the manufacturing unit for its implementation requires a high level calculations of the profiles of the blades of the turbines, their optimal spatial location between the working blades of the rotating speed and the availability of powerful water flow.

The challenge which seeks the invention is simpler and cheaper way to generate electricity antrotomy generator.

The technical result is high efficiency.

This technical result is achieved in that the rotation of the ro is ora and contrator towards each other is carried out by connection of the latter with high-speed linear motor with two protivovirusnaya disk rotor of large diameter and, as a result of counter-rotating is the addition of two angular velocities and two reinforced double blocks torques, which leads to increase capacity and improve efficiency.

The drawing shows a structural diagram of a device implementing this method, horizontally arranged vertical) position of the rotation axis.

The proposed device is an open inertial-torsion, the Electromechanical system of two protivovazdushna stages with the inertial reference system, consists of a helical contrating generator 1 contrataram 2 and the rotor 3 from the high-speed linear motor coil 6 and with two protivovirusnaya disk rotors 4 and 5 of a large diameter, on the edge of the circle which is perpendicular to them pinned secondary elements 7 and 8, the hub 9 of the rotor disk 4 is attached to the flange of the rotor shaft 3, forming the first stage of rotation in the form of a double block of the disk rotor 4 with radius Rn and the rotor 3 with radius R where Rn more R n times, which are located on the same shaft with the slide bearings 11 and the hub 10 of the disk rotor 5 is fixed to the body of contrator 2, forming the second stage of rotation of the disk rotor 5 and contrator 2 in the form of one double block with a difference of radii as n times, arranged coaxially with the rotor shaft 3 with what alienam on bearings 12, also consists of an electronic control unit (not shown) and the system of forced cooling of the inductor with channels for circulation of coolant (not shown). The inductor 6 and the device (not shown) combine an integral part of this design in whole mechanism.

The method of generating electrical energy in this way is that the rotation contrating generator 1 is carried out by coupling of the high-speed linear motor with two protivorededus disk rotors 4 and 5 of a large diameter, in the inductor 6 is divided by the received electric power into two parts, each form of mechanical force and distribute between the two secondary elements 7 and 8, which under the action of attached forces perform the work, giving angular acceleration two protivorededus steps, represented by double blocks, thus enhance and bring both parts of mechanical energy to the generator 1, where they again unite, the result is this is the sum of the two torques and two angular velocities, thus increasing the power of the received energy, which is converted into an electric, direct to the consumer and implement it as follows.

When connecting the inductor 6 of the linear motor to AC are formed in the two magnet what's fields, which move in the longitudinal halves of the magnetic core in different directions with a certain velocity and induce currents in the secondary elements 7 and 8. As a result of interaction of magnetic fields and induced them currents arise electromagnetic force, under the action of the secondary elements 7 and 8 begin to move relative to the fixed inductor 6 in opposite directions with a speed equal to the moving speed of the magnetic field along the magnetic circuit. Mechanical traction forces generated by the secondary elements 7 and 8, is equal to the current on the electromagnetic forces are distributed between the secondary elements equally,

FEM=F1; FEM=F2; F1=F2. Closed secondary ring elements 7 and 8 convert their linear displacement in the rotational motion of the disk rotors 4 and 5 to which they are attached. Power adopts the definition of torque and speed is the angular velocity. Under these moments, protivovazdushna-speed devices become angular acceleration. The use of the device of the double block, allows you to locate the point of application of the applied force on the block of large radius, thereby to increase the torque and angular acceleration torque level, and mounted on a small block radius of the working body fur is ISM, to reduce the moment of resistance moment of inertia. The moment of forces acting on a single disk rotor at point a block of large radius is M1=FRn, and at the point In the block of small radius is M=FnR, M1=M. Now equal force will point In and follow the reverse order of the steps. The moment the opposing forces on one disk rotor at a point In a unit of small radius is MEM=FR, as at point a on the large block radius will be MEM=FR/n. The rule of equality of the moments big and small blocks is performed only when power is applied from the side of the block with a large radius, if on the contrary, this rule does not work. The value of M greater than MEMn times and MEMmore MEMn times, this proves that the double block n times increases the torque steps and n times reduces the torque reaction force. If a double block rotates with acceleration, the "Golden rule" (rule equilibrium) is not valid. When this requirement is met, this device consisting of two double blocks, doing work on the rotation of the rotor 3 and contrator 2, and the sum of these works allows the generator to convert the received mechanical energy into electrical energy. Counter-rotation allows excitation windings and armature for one turn intersect twice, which increases the frequency established what I electromotive force twice, and the resulting field generated by the joint action of currents of the armature winding and field winding, will remain stationary. Therefore, the generator is the addition of two angular velocities ω+ω=2ω and two points, reinforced double blocks, n M+n M=2n M, and the product of these parameters defines the power received by the generator,

2n M 2ω=4n Mω=4n R=ROG. From this is subtracted the total power loss PPGinherent in the conversion, and the remainder is the net power PEHgenerator. POG-RPG=PEH.

The energization and de-energizing of the windings of the generator is made by means of slip rings and slip ring brushes (not shown).

The electronic control unit monitors the performance of internal and external circuits of the device, regulates and stabilizes the parameters include, if necessary, protected against short circuit and overload protection, converts the frequency to the required size to obtain a certain speed of the secondary elements, switches the power to the coil from an external source to offline and Vice versa.

The cooling coil of the linear motor is carried out depending on the purpose and conditions. If the device is used on vehicles used the blowout flow in knogo air. When the device is rated loads remove heat cooling fans. For devices running on acropetally loads and in poorly ventilated spaces the best effect is achieved when using liquid gas circulating through the channels inside the magnetic core.

Closest to the proposed device is an Electromechanical actuator, consisting of a generator and two high-speed linear motors with disk rotors of large diameter mounted for rotation towards each other for rotation of the two working bodies of the same mechanism, and bilateral inductors high-speed linear motors mounted stationary in the housing opposite each other, with the hub of one of the rotor disk has a splined connection with the shaft of the generator, and the hub of the other of the rotor disk mounted on the shaft of the generator without any fixing (EN 2301489 C2, dated June 20, 2007, BI No. 17).

The disadvantage of this drive is that it consists of two high-speed linear motors with two inductors, as this work can be executed with a single inductor, the second inductor is additional material additional weight. The disadvantage is the fact that located in the plane of the disk rotors secondary elements are not allow to use is the substance of all the potential big circle through what's the point of application of the applied force is at some distance from the edge of the circle, and this reduces the torque. Located on a disk rotors, flywheels, are also considered a disadvantage because it increases the moment of inertia and reduce angular acceleration.

In the proposed device, these drawbacks are absent. It consists of a helical contrating generator 1 with an elongated solid shaft of the rotor 3, which is rigidly fixed to the core with the coil anchor, forcing the fan, the contact ring and the flange, there are two bearing 11 for rotating the shaft and all protivovirusnaya system in the device and two bearings 12 for axial rotation it contrator 2, to the body which is rigidly attached to the core with the field winding, the exhaust fan and the contact ring, in case there is a window for airflow volume; high-speed linear motor with two disk rotors of large radius 4 and 5, which are manufactured from composite materials for devices of low and medium power and weld metal for devices with large capacity, on the edge of the circle, perpendicular to them, fixed secondary elements 7 and 8 of aluminum tires in the form of shells, the hub 9 of the rotor disk 4 is bolted to the flange of the rotor shaft 3 and the hub 10 dis the new rotor 5 is bolted to the body of contrator 2, forming two protivovazdushna stage in the form of a double blocks, and in the immediate vicinity of the secondary elements, with a minimum air gap, the device still has the unilateral inductor 6 in the form of a segment of the magnetic core which consists of two longitudinal cores, with antiferromag gasket between them, and with the common winding is laid in a special way; from the electronic control unit includes a unit start and stop device, the control unit and auto adjustment parameters received and generated electric power, the unit thyristor frequency Converter, the power short-circuit protection internal and external circuits, and the switch block and connection; of the system of forced cooling of the inductor including the fan duct and the heat sink with a pump for the implementation of the circulation of liquid coolant through special channels inside the magnetic core.

The device can operate continuously for a long time, stop needed for prevention and for replacement brushes. It is distinguished by ease of manufacture, operation and maintenance, high reliability and efficiency, low cost. But the main difference is that its efficiency is greater than one.

Ask the numerical values given the WMD device. The radii of the disk rotor 1 m, the radius of the rotor and contrator (the radius of the air gap of the generator) to 0.1 m, the difference of the radii is equal to 10, the length of the secondary elements 6,28 m, width of 0.1 m, a thickness of 0.005 m, the inductor receives three-phase AC voltage 380 V, frequency 1308 Hz from the electronic unit has a pole division 0,06 m, provides the speed of movement of the secondary elements in opposite directions at 157 m/s or 565,2 km/h, creates a pulling force on one square centimeter of the active surface of the inductor 0.2 N, and 500 square centimeters - 100 N, having spent 15700 W of useful power, and taking into account the losses in the conversion efficiency of the inductor 0,6 will 26166 W total power of electricity, the force acting on a single disk rotor, 50 N, and the torque on the rotor of the generator is 10 times more than and equal to 500 Nm, the angular velocity is equal to 157 rad/s, the same torque and the same speed given contrator second disk rotor in the generator are formed two reinforced torque forces and their sum is equal to 1000 Nm and two angular velocity with the amount of 314 rad/s, the product determines the received generator power 314000 W, taking into account losses in the efficiency of the generator of 0.95 will be 298300 watts of useful power, the generator has one pair of poles, when the rotational speed of the rotor and contacts the rotor at 1500 rpm or 25 revolutions per second, the generator produces electricity with a frequency of 50 Hz. Determine the reaction force of the electromagnetic forces on the coil linear motor one secondary element. The total moment of forces counteracting determine by dividing the total capacity of the generator 314000 W at twice the angular speed of 314 rad/s, and get 1000 Nm, it is distributed between the two disk rotors 500 Nm, when transferring to the secondary element will be reduced 10 times and will be equal to 50 Nm, divided by the radius of the rotor disk, find the reaction force of 50 N. Received the equality of forces of action and reaction, to disrupt this equilibrium, it is enough to increase the power consumed by the coil linear motor, up to 28000 W and lower ceiling PTO generator to 280000 watts. In this interval the device will operate in normal mode. The efficiency of the device is equal to 10. With this indicator, having the energy to run, in the future, the device can provide the power your engine for their electricity, while the remaining power to bestow.

Such a device will find application in all spheres of human activity and will get rid of the use of internal combustion engines, thermal and nuclear power plants.
