SIX-PHASE THYRATRON INDUCTOR MOTOR WITH CONCENTRIC WINDINGS CONTROLLED BY THREE-PHASE SINE CURRENT Russian patent published in 2015 - IPC H02K19/06 H02K19/10 

FIELD: electricity.

SUBSTANCE: according to the invention the result is achieved at the expense of ratios of angular sizes of rotor poles with claw-like ledges, concentric windings and frequent - current method control. Six-phase high-speed thyratron inductor motor with concentric windings of stator, controlled by three-phase sine current, contains a stator with twelve poles and rotor with two poles. The motor stator is fitted with three-phase concentric windings. Windings of each of three phases cover simultaneously three poles and one stator pole placed in the middle of the three poles. Number of turns covering three poles of the stator is related to number of turns covering one pole of the stator, approximately as 1/0.73. The rotor is fitted with claw-like ledges. The control is performed using a frequent current method.

EFFECT: increase of rotational speed at the same frequency of commutation of phase currents, decrease of number of motor leads.
