SIX-PHASE VALVE-INDUCTOR MOTOR WITH MINIMUM NOISE, VIBRATIONS AND PULSATIONS OF TORQUE, METHOD AND DEVICE OF CONTROL Russian patent published in 2013 - IPC H02K19/10 H02K29/06 H02P25/08 H02P6/08 H02P6/16 

FIELD: electricity.

SUBSTANCE: in a six-phase valve-inductor motor derivatives of inductances of phase windings by an angle of rotor rotation have a sinusoidal shape, and higher harmonics are not available, due to certain ratios of angular dimensions of rotor and stator poles, and rotor poles have slants in axial direction. Besides, total currents of phase windings contain in their composition only zero and first harmonics and do not contain higher harmonics. It is achieved due to the fact that each pole of the stator is equipped with two windings, through one of which zero harmonic flows (a constant component), through the other winding current flows, having a sinusoidal shape. The amplitude of current of sinusoidal shape is equal to the DC value. Sinusoidal currents are formed with the help of a three-phase bridge inverter, and DC is generated with a half-bridge inverter. The relay-current method of control is used.

EFFECT: reduced noise and vibrations and increased evenness of torque of rotation.
