Abstract: A method for determining the position of the rotor of a synchronous alternating-current permanent-magnet machine, its particularity consisting of the fact that it comprises the steps that consist in:

injecting in the machine a high-frequency voltage superimposed on the voltage delivered by the machine control system;
measuring the current of the motor and extracting a current that is linked to the injected voltage;
obtaining from the injected voltage and from the corresponding current the electrical angle θ suitable to identify the position of the rotor.
