A system for determining an initial position of a rotor (9) of a PMSM motor includes a motor controller (2) coupled to a plurality of phase windings of the motor by means of an actuation circuit (3). A processor (12) and an interface circuit (14) are coupled to the processor and the phase windings. The processor determines if the rotor speed is zero, and if so causes the actuation circuit to sequentially apply voltage signals (Vab, Vba, Vac, Vca, Vbc, and Vcb) to the phase windings to produce corresponding phase winding current signals (Iab, Icb, Ica, Iba, Ibc, Iac) in the various phase windings. The phase winding current signals are sensed and digitized. The processor then determines a position of a magnetic flux path associated with the rotor by computing the initial position of the rotor from one of the digitized phase winding current signals associated with the predetermined magnetic flux path.
