초록 ▼

A control unit is arranged for a synchronous motor formed of a rotor provided with a magnet. The control unit includes a 180.degree.-conduction drive unit for performing 180.degree.-conduction drive of the synchronous motor, a 120.degree.-conduction drive unit for performing 120.degree.-conduction drive of the synchronous motor, a rotation speed calculating unit for calculating the motor rotation speed, a rotation-speed-vs.-efficiency table unit storing an efficiency relative to a rotation speed of the motor, and a drive method selecting unit for selecting an optimum drive method for the current rotation speed based on the current rotation speed and information stored in the rotation-speed-vs.-efficiency table unit. Thereby, the synchronous motor performs 120.degree.- or 180.degree.-conduction drive in accordance with the current rotation speed to achieve the drive with an optimum efficiency.
