<p>CLUTCH MOTOR ARRANGEMENT An improved clutch motor arrangement to be used, for example, for driving industrial sewing machines and the like, which is provided with a detection device for detecting the operation of a clutch mechanism and a control device for controlling voltages to be applied to the motor. The voltage impressed during no-load operation of the motor is lowered to the minimum necessary value required for the motor to rotate at a speed in the vicinity of synchronous speed for reducing power consumption during the no-load operation.</p> |
