Annotation: This paper presents results of a study on control system of sixphase synchronous motor with permanent magnets, built on the basis of the principle of predictive model. The objective of this work is to analyze speed control (torque control) of the rotor by controlling stator currents with stepwise speed acceleration and deceleration. A mathematical model of a six-phase synchronous motor and its structure is presented. A control algorithm with continuous selection of the inverter voltage vector has been developed. Simulation results show the effectiveness of the torque control method in balanced and unbalanced system operation modes.
