Abstract

The drive system connects a servomotor via a clutch to a shaft after the motor has started up from a standstill to a speed in synchronism with the supply frequency to the servomotor. The clutch may also be actuated to disengage the servomotor from the shaft when the servomotor is slowed to a predetermined speed during stopping of the servomotor. A transmission is employed between the servomotor and the shaft to compensate for any shocks to the motor when engaging the clutch.
