Abstract
A method for modulating torque of a vehicle propulsion motor driven by first, second and third cyclic currents mutually shifted by electrical angles of 120 degrees and applied in accordance with a rotating magnetic field by a rotor is provided with: applying pulse-width modulated voltage pulses respectively to switching devices to generate the first, second and third cyclic currents; and adding a phase shift to the first, second and third cyclic currents relative to the rotating magnetic field, or causing an amplitude modulation in the first, second and third cyclic currents.
