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.
Claims1
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 angel command value of said spindle and a rotational angle feedback value thereof, and which applies its integral output to the driving amplifiers in common, wherein the rotational angle feedback value of said spindle consists of a sum signal between velocity feedback signals of said two motors.
