A motor control system for individually feedback-controlling a plurality of servomotors includes: a plurality of motor drive devices for converting DC power into AC power to drive the servomotors; current detecting devices for detecting the current value of the AC current to feed it back to the motor drive devices; and an A/D converter for converting the output signals of the current detecting devices into a digital signal. The motor drive devices, current detecting devices and A/D converter are accommodated in a casing for a group of servomotors, and the output terminals of the current detecting devices in the casing are connected in parallel to the input terminal of the A/D converter, so that the A/D converter is used for all of the current detecting devices in the casing. The resultant motor control system is small in the number of components, and accordingly in the number of wiring conductors, and is simple in construction and accordingly in adjustment work.
