A method for controlling the electromagnetic torque of a three-phase synchronous machine with permanent magnets, which comprises measuring the current delivered to the three phases of the machine, transposing the three measured currents into a direct current component (Id) and a quadratic current component (Iq) using Park's transformation, and receiving an instruction (Iq_req) for the quadratic current component (Iq). When the direct current component (Id) is negative, a defluxing control mode is activated in which the machine is controlled from a direct voltage component (Ud) and a quadratic voltage component (Uq) of said machine, the direct voltage component (Ud) and the quadratic voltage component (Uq) being determined in Park's plane. |
