A method wherein the signals (SW1, Sw2, Sw3) controlling the power supply (10) of the phase windings (4) of the motor consist of signals (So1, So2, So3) that are out-of-phase by a phase angle (f) which is continuously variable in relation to synchronization signals (Si1, Si2, Si3) generated by sensors (1) detecting the position of the rotor. According to the method, a processing unit (5) comprises inlets (8) for receiving the synchronization signals and outlets (6, 7) for transmitting the out-of-phase signals. The synchronization signals are binary signals presenting synchronization fronts and the rising and falling fronts of the out-of-phase signals are generated, following a level switching time depending at least on the phase angle, from at least one reference front selected from the synchronization fronts such that the switching time is minimum.
