FIELD: electricity.
SUBSTANCE: single-phase asynchronous motor start-up method is simultaneous supply of the AC or DC voltage to the additional stator windings together with the supply of the AC voltage to the main and auxiliary stator windings that create saturation of the stator yoke sections in the magnetic axis regions of the main winding, and after the motor start-up, disconnection of the auxiliary and additional stator windings.
EFFECT: boosting the starting torque.
