METHOD OF PRODUCING DRIVING FORCE IN ELECTRIC MOTORS Russian patent published in 2025 - IPC H02K1/06 H02K21/14 

FIELD: electrical engineering.

SUBSTANCE: method of obtaining driving force in electric motors includes successive change of magnetic forces of interaction of poles of movable and fixed parts along movement of movable part, connection of winding to power supply source, changing the air gap between the poles of the movable and fixed parts, changing the amount of magnetic material. Motive force is created unidirectional by means of successive change of magnetic forces of interaction of poles of magnets of the movable part and ferromagnetic material of the fixed part in the direction of movement of the movable part. Change of magnetic forces of interaction of poles of magnets of movable part and ferromagnetic material of fixed part is carried out successively on sections, number of which is n≥1, each of which is characterized by presence of uniformly varying values of magnetic interaction forces from minimum to maximum at their respective ratio within range of 1:2-1:100. Transition from maximum value of magnetic forces of interaction of one section to minimum value of another section is performed by connection of winding of fixed part to power supply source.

EFFECT: reduction of electric power consumption.
