Claims

[Scope of utility model registration request]

A rotor pole with a field coil is installed on the flywheel side, and a stator coil that mutually forms a rotating magnetic field with the rotor pole is provided on the fixed housing side facing the rotor pole through a predetermined gap. Control of an engine in which a stator pole is installed and the applied current supplied to the rotor pole side field coil or the stator pole side stator coil is appropriately controlled according to the operating state of the engine to function as a generator or an electric motor. The device includes a clutch disengagement detection means for detecting a disengaged state of the clutch, a current cut means for stopping the supply of the applied current when the clutch disengagement detection means detects that the clutch is disengaged, and the clutch disengagement detection means. The present invention is characterized by further comprising current suppressing means which operates in response to the current cutting means to apply a constant voltage to the rotor pole side field coil to suppress the residual current when disconnection of the clutch is detected by the rotor. engine control device.
