FIELD: electricity.
SUBSTANCE: method of controlling the electromagnetic torque of a three-phase synchronous machine with permanent magnets, including measuring the current applied to three phases of the machine, converting the three measured currents into a constant component (Id) and the quadrature component (Iq) of the current based on the conversion of the Park, obtaining the set value (Iq_req) for the quadrature current component (Iq). If the permanent current component (Id) is negative, the control mode with a reduction of flow is activated, at which the machine is operated on the basis of the permanent component (Vd) and quadrature voltage component (Vq) of the specified machine, wherein the constant component (Vd) and quadrature voltage component (Vq) of the synchronous machine control is determined in the plane of the Park.
EFFECT: stability of currents in a synchronous machine when it operates with high speed and saturation voltage.
