None of said known technical solutions are suitable for the solution of the task herein stated.

Therefore the object of this technical solution is to provide a method of converting magnetic energy into mechanical energy.

It is suggested to achieve the object above stated using a method of converting electromagnetic force interaction into mechanical energy comprising the supply of alternating or pulsed current to an exciting coil with a core and a compensating coil, said coils being interconnected, and the action of the alternating magnetic field so produced onto a permanent magnet attached to a servo motor and capable of moving in the alternating magnetic field range thus having said servo motor performing work to generate mechanical energy.

It is suggested to implement said method using a device comprising an alternating or pulsed current source, at least one exciting coil with a core and at least one compensating coil, said coils being connected to one another and to said current source, and a servo motor comprising a permanent magnet attached to said servo motor and capable of moving in the alternating magnetic field range thus having said servo motor performing work to generate mechanical energy. Preferably, an even number of exciting coils and/or an even number of compensating coils are used.

The essence and advantages of this technical solution will be disclosed hereinafter using its different embodiments.

The technical solution disclosed herein can be implemented using the device schematically shown in Fig. 1. The device comprises a coil winding current control electronic system 1 , a unit 2 which matches the coil current direction and permanent magnet movement direction switching phases, a mechanical power takeoff shaft 3, a crank mechanism 4, a rod 5, the shell 6 of a permanent magnet 7 said shell being made from a magnetotransparent and electrically nonconducting material rigidly connected to the rod 5 and the permanent magnet 7, an exciting coil 8 and a compensating coil 9. The electronic control circuit is an electronically controlled thyristor (here, a symistor) rectifier capable of generating the required polarity, amplitude, shape and duration voltage, the phase matching unit is an electronic circuit activating at the required moment of time to send lock/unlock signals to the electronic control unit thyristor, and the shell can be made from a hard insulator, e.g. ceramic or phenolformaldehyde resin polymer.

The device operates as follows. When the permanent magnet 7 is in the rightmost position relative to the coils 8 and 9, the electronic circuit 1 supplies the winding of the exciting coil 8 with current of suitable direction and amplitude which drives the permanent magnet 7 to the leftmost position thus generating some mechanical energy. In the course of the movement the rod 5 transmits the movement of the permanent magnet 7 to the crank mechanism 4 which moves to turn the shaft 3 through 180°. As the permanent magnet 7 reaches the leftmost position, the position of the shaft 3 signals the phase matching unit 2 which generates a control signal for the electronic control circuit 1 to change the supply voltage polarity. This causes a change in the polarity of the magnetic field flux enveloping the exciting coil 8. Said field of the coil 8 acts on the permanent magnet to drive it from the leftmost to the rightmost position and transmit the movement energy to the shaft 3 through the rod 5 and the crank mechanism 4. The changing polarity of the magnetic field flux enveloping the exciting coil 8 provides for the cyclic movement of the permanent magnet and eventually shaft rotation.

In accordance with the electromagnetic induction law, the high-speed movement of the permanent magnet 7 induces electromotive force in the winding of the exciting coil 8 which prevents the generation of a magnetic field that would accelerate the permanent magnet, i.e. said electromotive force is directed against the current supplied by the electronic control circuit 1. To avoid this action of the electromotive force, the device further comprises the compensating coil 9 electrically connected to the exciting coil such that the high-speed movement of the permanent magnet 7 also induces electromotive force in the compensating coil 9 oriented in the same direction as the supply current. The parameters of the compensating coil 9 are chosen so that the main magnetic flux generated by the coil 9 to accelerate the permanent magnet 7 is amplified due to the high-speed movement of the magnet. The coil 9 decelerates the movement of the permanent magnet 7 by its magnetic flux, but as the coil 9 has no core the negative magnetic component in its resultant magnetic flux is far lower compared to the magnetic flux generated by the coil 8. The main magnetic flux of the exciting coil 8 does not decrease due to the high-speed movement of the permanent magnet; on the contrary, it even increases because the core of the coil 8 is unsaturated.

The electrical power consumed in the control circuit, the switching power losses, the heating losses in the copper winding and the eddy current losses in the core are far lower compared to the mechanical energy output of the device.

Devices based on the principle above described can be used in motors of various vehicles and as generator drives for independent power supply.

The losses in the compensating part of the device can be reduced by reducing the size of the compensating coil 9 and installing two said compensating coils 9 perpendicular to the core axis of the coil 8 and its butts; then the permanent magnet 7 will move between said compensating coils 9 parallel to the exciting coil.

Other embodiments of this method are possible.

For example, to reduce the weight and dimensions of the device and increase the speed of the permanent magnet and hence the shaft thus increasing mechanical energy output, it is recommendable to use magnet rotation instead of reciprocation. The use of this technical solution allows converting magnetic energy into mechanical energy.
