ABSTRACT:
A motor vibration control device includes a speed adjusting unit for outputting a driving torque reference value based on the difference between a speed reference value to a motor and a detected speed value of the motor; a current adjusting unit for adjusting the current to be provided for the motor and outputting a driving torque value based on the current; a compensation torque calculator for calculating a compensation torque value based on the detected speed value, the driving torque reference value, and the driving torque value; an amplifying unit for amplifying the compensation torque value; and an adder for adding the driving torque reference value to the amplified compensation torque value and outputting the sum to the current adjusting unit. With this simple circuit configuration, the device suppresses the torsional vibration generated by an operating motor.
