An electronic power supply for a synchronous motor with permanent-magnet rotor with two pairs of poles, wherein the windings of each pair of poles are supplied by a corresponding electronic circuit; one of the circuits comprises a capacitor (17) which acts as a 90 DEG phase shifter, and a static switch (18) is also present on at least one of the two circuits and is controlled by a sensor (20) for detecting the position of the rotor. <IMAGE> |
