ASYNCHRONOUS ELECTRIC MOTOR WITH HIGH EFFICIENCY FACTOR Russian patent published in 2015 - IPC H02K1/00 H02K17/10 

FIELD: electricity.

SUBSTANCE: invention pertains to the field of electric engineering, and namely to salient-pole asynchronous motors, and may be used in electric drive used for different engineering and household applications. The asynchronous electric motor comprises the stator core including polar tips and yoke assembled of electric steel sheets, a cage rotor mounted in the stator bore, the stator winding consisting of coils installed at the poles; the body is made of non-magnet material with the rigidly fixed stator core consisting of one pair of poles and yoke where resonant winding is mounted with a tuning capacitor, at that the polar tips and yoke are made as one piece.

EFFECT: improvement of the motor efficiency factor and significant reduction of consumed power.
