たことを特徴とするモータの揃速運転装置。 The main motor and sub motor are operated at the same speed, and the current flowing through the motor is detected for each motor, and the phase of the main circuit switching element of the power converter is determined based on the deviation between the current detection signal and the current setting signal. In the control device, a speed setting section for the main motor and a speed amplifier for the main motor are provided, and the deviation between the speed setting signal set by the speed setting section and the detection signal corresponding to the main motor speed is detected by the speed amplifier. A constant speed driving device for a motor, characterized in that the amplified output signal is used as a current setting signal for a main motor, and the current detection signal of the main motor is used as a current setting signal for a sub motor.
