PURPOSE:To precisely control and to easily increase capacity by dividing torque necessary to drive, and rotating a plurality of motors according to a plurality of controls based on the divisions. CONSTITUTION:A plurality of motors 6a, 6b connected to a plurality of AC supply means for driving a predetermined load, detecting means 18 for detecting in a plurality of types from a load, etc., a signal for determining a torque necessary to drive the motors, and control means 13a, 13b for controlling the generated torques of the motors 6a, 6b based on the plurality of detection signals are provided. A torque necessary for a load is divided, and the motors 6a, 6b are rotated by a plurality of controls based on the divisions. |
