    摘要: Provided is a synchronous motor including a rotor having magnetic poles distributed circumferentially along a rotation direction of the rotor at equal intervals, and a stator having stator teeth arranged circumferentially along the rotation direction of the rotor, each tooth wound with a stator coil by concentrated winding. Every M consecutive stator teeth belong to one of stator teeth groups arranged at equal intervals. The M consecutive stator teeth in each stator teeth group are arranged at intervals different from the intervals of the magnetic poles of the rotor. The stator coils wound around the M consecutive stator teeth are connected to separate terminals. A motor driver supplies currents of different phases to the stator coils via the respective terminals.

    摘要: A high-side MOSFET (12) is connected in parallel to a high-side MOSFET (11) via an inductor (13). When the flow-out of a current is started, the high-side MOSFET (12) is turned on earlier. A recovery current of a body diode (21a) of the low-side MOSFET (21) flows via the inductor (13) and the high-side MOSFET (12), and therefore, the rate at which the current changes over time can be suppressed to a lower level. Thereafter, the high-side MOSFET (11) for a main current is turned on, and the high-side MOSFET (12) for suppressing a recovery current is turned off, whereby the former causes a current to flow out. When the high-side MOSFET (11) to turned off to stop the flow-out of a current, surge is not caused by the inductor (13).
