(57) Abstract:

Usage: the production of electrical energy. The technical result is to create a magnetic generator with high efficiency by using energy permanent magnets.

Their cores are composed of a magnetic core and a permanent magnet with a pronounced magnetic field. Between the magnet and the magnetic core forming a closed magnetic flux, there is a gap to navigate through screens. The screens are attached to the ends of the permanent magnets of the rotor is made of a nonmagnetic material. The number of rotor magnets differ from the stator magnets on one unit, and the magnetic field is oriented different. 4 Il.

The invention relates to the production of electrical energy.

The known magnetic generator, comprising a housing, a ferromagnetic stator in the form of a disk, which is fixed to the first anchor group of coils with cores, the rotor with the shaft, the annular magnetic core with teeth and a permanent magnet with axial magnetization, the qi of the windings which, as the ends of the windings of the coils of the first group, displayed on terminals, mounted on the pads of the housing, the bearings of which is secured the rotor shaft (Application N 95103846 A1, IPC 6 H 02 K 21/14, 1996).

Also known magnetoelectric generator, installed in the containing casing can be rotated inductor in the form of an axially magnetized magnet salient pole tips, and a working winding located on the magnetic circuit of the stator. The magnetic circuit of the stator is made of U-shaped, uniformly distributed on a circle with a line opposite poles of the magnet to the tip of the inductor, the number of cores is equal to twice the number of poles of the magnet tip of the inductor, and the adjacent windings connected in series and opposite in the case of providing an alternating voltage or under in the event that a unipolar pulsed voltage (Patent of Russian Federation N EN 2053591 C1, IPC 6 H 02 K 21/12, 1991).

The disadvantage of these generators is the low coefficient of performance (COP). The most the closest analogue is the magnetoelectric generator (Patent of Russian Federation N EN 2053591 C1, IPC 6 H 02 K 21/12, 19991,).

The objective of the invention is to achieve viscerator includes a housing, made of non-magnetic material, which is still installed and evenly distributed around the circumference of the core and working the stator winding, at least one core working of the stator winding consists of a magnetic core and two-pole permanent magnet, and between the double-pole permanent magnet and the magnetic core has a gap for movement therein magnetic shields attached to the ends of the double-pole permanent magnet installed on the rotor, made of non-magnetic material on the rotor, in contrast to the stator, the number of bipolar permanent magnets is less than or more than one unit, poles are oriented to the poles of the double-pole permanent magnet stator opposite.

In Fig. 1 shows a magnetic generator, longitudinal section. (Conditionally).

In Fig. 2 schematically shows a rotor, front view and side.

In Fig. 3 schematically shows the moment of a closed magnetic flux through the magnetic core of the working winding and momentum of a closed magnetic flux between the two pole permanent magnets.

In Fig. 4 shows a connection diagram of the working windings through will straighten the casing 1, made of non-magnetic material, which is still installed and evenly distributed around the circumference of the cores and operating winding 2 of the stator, at least one core operating winding 2 of the stator consists of a magnetic core 3 and the double-pole permanent magnet 4, and between the double-pole permanent magnet 4 and the magnetic core 3 has a clearance for movement therein magnetic shields 5, secured to the ends of the double-pole permanent magnet 6 mounted on the rotor 7, is made of non-magnetic material, the rotor 7, in contrast to the stator, the number of two-pole magnet 6 is less than or more than one unit, poles are oriented to the poles of bipolar magnets 4 of the stator opposite.

Magnetic generator works as follows.

During rotation of the rotor 7, the time of closest approach, at least one bipolar permanent magnet 6 mounted on the rotor 7 with one bipolar permanent magnet 4 of the core working of the stator winding, there is an interaction summed to each other of the opposite poles. Between the two pole permanent magnets 4,6 formed of closed magnitudine working stator winding, the magnetic flux is absent, and therefore the EMF on the working of the stator coil 2 is also missing.

Further, in the moment of the greatest removal of the double-pole permanent magnet 6 mounted on the rotor 7, a bipolar permanent magnet 4 of the core working of the stator winding, the magnetic fluxes between these two pole permanent magnets are broken.

The magnetic flux from the pole N pole of the permanent magnet 4 of the core working of the stator winding rushes to its S pole through the magnetic core 3, which is a part of the core working of the stator winding. In the working coil 2 of the stator under the influence of a time varying magnetic flux occurs EMF. With the approach of the double-pole permanent magnet 6 mounted on the rotor 7, a bipolar permanent magnet 4, which is a part of the core operating winding 2 of the stator, the cycle repeats. Magnetic screens 5, secured to the ends of the double-pole permanent magnet 6 mounted on the rotor 7, perform auxiliary function: being in the gap between two pole permanent magnet 4 and the magnetic core 3 core working of the stator winding, these magnetic akoni must be made of magnetic material.

2) the Hysteresis loop should be narrow. The number of working windings 2 of the stator in the magnetic generator is determined by the estimated technical parameters.

On the rotor 7, in contrast to the stator, the number of bipolar permanent magnets 6 is less than or more than one unit, it is this interaction of the magnetic fields of two-pole permanent magnets of 4.6, which contributes to cost reduction of the mechanical energy required to create a rotating torque on the rotor 7, which has an impact on increasing the efficiency of the magnetic generator.

The obtained electric current through a rectifying diode bridge is served to the consumer. Capacitor available in the schema, is used to smooth out pulsations.

Magnetic generator containing the working winding and the stator cores, permanently installed in the housing and evenly distributed around the circumference of the rotor with the shaft, characterized in that the cores of the working of the stator winding consists of a magnetic core and a permanent magnet forming a closed magnetic flux and clearance to navigate through screens, attached to the ends made of non-magnetic material of the rotor permanent magnets, screens of obespechivala, while permanent magnets of the rotor and stator in the magnetic field oriented bipolar, and the number of different unit.
