VECTOR CONTROL DEVICE OF ASYNCHRONOUS MOTOR SPEED Russian patent published in 2014 - IPC H02P21/04

Abstract RU 2524507 C1

FIELD: electricity.

SUBSTANCE: proposed device includes a calculation unit that calculates speed and flux linkage parameters under conditions of insignificant variation of external moment M_c. This allows maintaining maximum and constant motor efficiency within the whole allowable range of variation of external moment at the specified angular speed without using any speed sensor mechanically connected to the motor shaft and a unit of sensors of the main flux linkage, which are arranged in the gap of the stator.

EFFECT: maintaining maximum and constant motor efficiency within the whole allowable range of variation of external moment at the specified angular speed.
