SCHEME AND METHOD OF CONTROLLING A REACTIVE ELECTRICALLY COMMUTATED MOTOR Russian patent published in 2018 - IPC H02P25/92 H02P25/18 H02P6/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the scheme and method for controlling a reactive electrically commutated motor. Electronic control unit provides commutation of the circuits in such a way that the reactive electrically commutated motor has a first winding structure, when with respect to the boundary dividing the range of activation of the commutated reactive electric motor into two ranges, – the torque and the rotational speed of the commutated reactive motor, which are determined in accordance with the applied voltage, are in the first range on the low load side. Electronic control unit provides commutation of the circuits in such a way that the reactive electrically commutated motor has a second winding structure, when the torque and the rotational speed of the commutated reactive motor are in a second range that is differ from the first range.

EFFECT: increase of the maximum torque of the commutated reactive electric motor.
