SINGLE-PHASE ASYNCHRONOUS MOTOR Russian patent published in 2014 - IPC H02K17/08 H02K1/16 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering, namely to single-phase asynchronous motors with a starting winding, and can be used for electric tools and household appliances, for example in refrigerant compressors subject to essential shaft load at start-up and common operating conditions at the mains low voltage. In a single-phase asynchronous motor containing a rotor and a stator with slots with placed main and auxiliary windings with magnet axes shift in regard to each other per a half of polar pitch according to the invention in the area of stator slots located in the areas of the main winding magnet axes there are through nonmagnetic gaps filled with air or nonmagnetic inserts.

EFFECT: technical result attained by use of this invention lies in increase of staring electromagnetic torque of the single-phase asynchronous motor thus ensuring reliable start-up at increased shaft load.
