SINGLE-PHASE ELECTRIC MOTOR Russian patent published in 2011 - IPC H02K17/08 H02K1/14 

FIELD: electricity.

SUBSTANCE: electric motor includes rotor and stator with the main and auxiliary poles with pole tips and windings offset relative to each other through the half of pole pitch along poles of the main phase, as well as non-magnetic through gaps are made in stator yoke and pole tips, which are adjacent to them. Yoke is common for both systems of poles, and poles of auxiliary phase and stator yoke and pole tips, which are adjacent to them, are solid.

EFFECT: increasing electromagnetic starting moment of electric motor, which can provide reliable start-up at availability of increased load on shaft.
