ABSTRACT:
Provided is a drive regenerative control system of a drivee with a motor superior in torque and weight balance and suitable for miniaturization as the drive source. In a drive regenerative control system having a drive source with an electric motor, a drivee, a control circuit having a drive control circuit of the motor and a regenerative control circuit, and a detection unit for detecting the driving status of the drivee, the drive control circuit and regenerative control circuit have a control unit for controlling, linearly or in multiple stages, the duty ratio of the drive or regenerative signal to be supplied to the motor based on the phase difference of the phase of the detection signal from the detection unit and the command value signal to the motor.
