Abstract

PURPOSE: To suppress the speed vibration of a motor under a stationary condition, by applying negative bias to a speed controller while mounting a compensation circuit by means of a diode between the speed controller and a drive circuit of the motor.
CONSTITUTION: A diode 14 is connected between a speed controller 1 and a current controller 2 while a variable resistor 13 is connected between an outer end of the speed controller 1 and a negative power source under constant voltage, and input is connected to a movable contact of the movable resistor 13 through a resistor 11 and a diode 12. The bias of positive voltage in the extent that does not exceed the forward direction drop voltage of the diode 14 is applied to speed deviation signals 1a by adjusting the variable resistor 13. Thus, the speed deviation signals 1a are interrupted when voltage is not more than the forward direction drop voltage of the diode 14, and the generation of vibration in the torque of a motor can be oppressed under a stationary condition.
