ABSTRACT:
Apparatus and method for periodic rotation of the rotor assembly of a turbogenerator during the time that it is not rotated in its normal manner for generating power, in which a continuously operating motor is periodically connected through an electrically controllable, torque-speed, clutch mechanism and a gear train to a gear mounted on the rotor shaft so as to rotate the shaft by 180.degree. at a slow speed. The position of the rotor is measured by electrically counting the teeth of the gear on the rotor shaft, and the count of teeth is compared with a preset number in a counter which after the count set in the counter is reached, disconnects the motor from the rotor gear and sets a brake. A settable timer periodically releases the brake and connects the motor to the rotor gear. The apparatus can include a recorder for recording rotation of the shaft and an alarm for indicating failure of rotation of the rotor when the timer provides a start signal.
