FIELD: electricity.
SUBSTANCE: invention refers to control method of salient pole electric motor with permanent magnets, as well as control device (system) which allows using reactive torque moment of electric motor with IPM internal permanent magnets. The proposed method involves signal measuring pitches of counter-electromotive force of deenergised phase winding of electric motor with permanent magnets and supply of the first excitation voltage at least to one of other phase windings of electric motor with permanent magnets; at that, the above first excitation voltage is displaced in phase relative to measured signal of counter-electromotive force. Besides, this invention refers to peculiar features of the design of control system implementing the above method.
EFFECT: providing the possibility of using reactive component of torque moment of electric motor with internal permanent magnets, and control device is simple and stable.
