  First, when functioning as driving assistance, DC power is supplied from an external battery to the power circuit unit 18. The supplied DC power is converted into a three-phase AC current by ON / OFF control of the switching element of the power circuit unit 18. The three-phase alternating current from the power circuit unit 18 is supplied to the stator winding 11.

  Further, the DC power supplied from the external battery is adjusted by the field circuit unit 19 and supplied to the rotor winding 6, so that a rotating magnetic field is generated around the rotor winding 6. Thereby, the rotor shaft 4 and the rotor 5 are rotated with respect to the stator 12.

  The rotation of the rotor shaft 4 is transmitted from the pulley 13 to an engine (not shown) via a transmission belt (not shown).

  The control circuit unit 20 controls the power circuit unit 18 and the field circuit unit 19 based on information from the external device and the rotational position detection sensor 14.
