FIELD: electricity.
SUBSTANCE: result is achieved by a special configuration of a motor magnetic conductor and a control circuit, which makes it possible to generate unipolar currents of phases, having a shape of "detected sinusoid" and amplitude-controlled with the help of an inverter, which consists of three half-bridge circuits of a rotor position sensor and a control system.
EFFECT: reduced torque pulsation.
