ABSTRACT:
The present invention relates to a motor driving device wherein two motors are held in engagement with an identical spindle through respective torque transmission mechanisms, and wherein each of the motors has a driving amplifier for generating a torque in a direction reverse to that of a torque of the other motor; comprising an integration circuit which integrates with respect to time a difference signal between an angle command value of the spindle and a rotational angle feedback value thereof, and which applies its integral output to the driving amplifiers in common.
