ABSTRACT:
A multi-spindle synchronous drive unit for synchronously driving a plurality of spindles, includes a plurality of motors for respectively driving the spindles, a plurality of encoders for respectively detecting rotational positions of the motors, a plurality of phase locked loop control units for respectively controlling a drive of the motors and for receiving as feedback signals detection signals respectively output by the encoders, a reference pulse oscillator for outputting a pulse signal, and a plurality of multipliers for multiplying the pulse signal by multiplication factors respectively corresponding to rotational speed ratios of the spindles and for respectively outputting speed command pulse signals to the phase locked loop control unit.
