FIELD: electricity.
SUBSTANCE: single-phase induction motor comprises a rotor and a stator with slots, where main and auxiliary windings are installed, forming nonsalient poles with displacement of magnetic axes relative to each other by half of a pole division. In the stator yoke in the field of slots arranged in zones of magnetic axes of the main winding, there are non-magnetic gaps with formation of saturation bridges.
EFFECT: higher start-up torque of a single-phase induction motor.
