SINGLE-PHASE ELECTRIC MOTOR Russian patent published in 2012 - IPC H02K17/08 H02K1/14 

FIELD: electricity.

SUBSTANCE: in single-phase electric motor containing rotor and stator with the main and auxiliary poles with pole tips and windings offset relative to each other through the half of pole division of the system, along the axes of poles of the main phase and in stator yoke adjacent to them and in pole tips there made are non-magnetic through gaps; stator yoke is one and the same for both systems of poles, and poles of auxiliary phase and stator yoke and pole tips, which are adjacent to them, are one-piece. According to the invention, non-magnetic gaps of poles of the main phase, stator yoke adjacent to them and pole tips are made with formation of saturation bridges in the area or poles of the main phase, or stator yoke adjacent to them, or pole tips, or simultaneously in the area of stator yoke and pole tips.

EFFECT: simpler manufacturing procedure of single-phase asynchronous motor with auxiliary winding and increased starting torque.
