In the control mode for starting rotation of the crankshaft, on/off-operation of the plurality of switching parts is performed at predefined timings. In the control mode for accelerating the rotation of the crankshaft, on/off-operation of the plurality of switching parts is performed at timings based on an electrical signal flowing in the detection-purpose winding of the rotor position detection device. The electrical signal varies depending on a variation in the magnetic condition caused by movement of the plurality of detection object parts along with the rotation of the crankshaft.
