Abstract
A motor control system includes a processor having a clock output terminal for outputting clock pulses in desired cycles, a plurality of motors, and a plurality of motor drivers which are provided one for each motor and drive the corresponding motors on the basis of the clock pulses input into the motor drivers through their respective clock input terminals. The clock input terminals of the motor drivers are connected to the clock output terminal of the processor in common with each other.
