ABSTRACT:
When an electric compressor is activated, initial current data is selected by a selector, and a motor is driven with the torque corresponding to the initial current data. When the motor is driven by a ½ turn, the selector selects current difference data. The current difference data corresponds to an instructed speed. After the switch of the selector, the motor is driven to rotate at the instructed speed.
