The gear consists of two halves 5.1, 5.2, .Q and poles 6-17, in the slots of which the coils 18-29 of the core winding are connected, connected according to the scheme shown in FIG. 3, and forming phases ax, by C C windings core, and the sensor of the angular position of the rotor a, the coil 30-41 primary winding fg (Fig. 3) and the coil 42-53 of the secondary winding he dk, Ira which are located at the poles 6-17 and interconnected according to the scheme shown in Fig about 3.

The motor works in the following way.

When applied to the primary winding of the rotor angle sensor fg of a high-frequency alternating voltage, the magnetic fluxes generated by the primary windings, located at poles 6-17, interlock with the secondary windings located at the same poles.

As a result, they induce EMF of mutual induction, the amplitudes of which, when the rotor rotates, change in accordance with the change in conductivity of the air gap under the poles 6-17. Turning on the coils 30-4.1 and 42-53 (FIG. 3) eliminates the mutual inductive coupling of these coils and magnetic fluxes from permanent magnets and from

When the secondary winding he, dk, 1m is connected to the semiconductor switch, which powers the winding phases of the electric motor, the currents in the phases will vary in accordance with changing the angle of rotation of the rotor, creating a torque.

Thus, the invention makes it possible to create a valve motor based on an electromechanical actuator with permanent magnets arranged together with a winding of the core on the stator, which has improved technological and mass dimensions due to a smaller number of permanent magnets than known
