MOTOR UNIT AND GEAR POWER TRANSMISSION DEVICE

摘要

A motor unit is realized which does not continue to drive a driven member in an abnormal state when wiring of any one motor has been disconnected. The motor unit comprises a plurality of motors. An output shaft of each of the plurality of motors engages with one driven member. The motors are electrically connected in series. Since the plurality of motors is electrically connected in series, all the motors stop when the wiring of any one motor has been disconnected. The driven member does not continue to be rotated by the remaining motors when the wiring of any one of the motors has been disconnected.
