LOW-SPEED ASYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2011 - IPC H02K17/16 H02K17/12 

FIELD: electricity.

SUBSTANCE: low-speed asynchronous electric motor includes stator with multi-phase winding and rotor with interleaved core and short-circuited winding. Stator phases are made in the form of annular windings coaxial with rotor, each of which is located between two annular magnetic cores with teeth protruding in axial direction and which are opposite directed. At that, annular magnetic cores of the phase are offset relative to each other through π/z angle, and between them there arranged is toroidal magnetic core, and annular magnetic core of various phases are offset relative to each other through 2π/z·m angle, where z - the number of teeth of each annular magnetic core, and m - the number of phases.

EFFECT: simplifying the manufacturing procedure of the stator windings at simultaneous technically possible increase of the number of poles of low-speed asynchronous electric motor.
