The motor comprises at least a stator winding (2) supplied through an electronic commutation circuit (3) in accordance with a driving signal generated by a sensor provided to detect the angular position of the permanent-magnet rotor (1). The sensor comprises an inductive coil (7) which is magnetically coupled to the rotor (1) and is arranged at 90 electrical degrees with respect to the stator winding (2), so that said driving signal (Ui) is induced in the sensor (7) with a corresponding phase shift with respect to the voltage (EMF) induced in the stator winding (2). <IMAGE>
