Abstract
A centrifugal actuator of an electric motor is modified to reduce noise produced by torque pulses of the motor. The centrifugal actuator comprises a damper sleeve that is mounted in a tight friction fit on the motor shaft. The main body of the centrifugal actuator is mounted on the damper sleeve by a friction fit which permits limited rotational movement of the actuator main body relative to the actuator damper sleeve. In addition, pairs of tabs are provided on both the actuator main body and the actuator damper sleeve and are positioned in circumferentially overlapping relationships whereby engagement of the main body and damper sleeve tabs provides a positive driving connection between the main body and damper sleeve.
