Electric compressor
An electric compressor includes a rotary shaft that is driven by an electric motor. The motor generates driving torque. Pistons compress gas in accordance with rotation of the rotary shaft. During one turn of the rotary shaft, the times when the net load torque generated by the pistons is minimum and the times when the driving torque of the motor is minimum occur at substantially the same rotation angles of the rotary shaft. Also, during one turn of the rotary shaft, the times when the net load torque is maximum and the times when the driving torque of the motor is maximum occur at substantially the same rotation angles of the rotary shaft. The driving torque is always greater than the net load torque. Therefore, the motor need not be large to generate sufficient torque.
