Abstract: A vibration absorber is provided for reducing noise and vibration emanating from an electric motor, or another vibrating object, and the surrounding structure to which it is mounted. The vibration absorber has a beam with a mass secured thereto. The vibration absorber is mounted externally to the motor, in a direction perpendicular to an axis of torsional vibration of the motor. The absorber is tuned to have a resonant frequency corresponding to the torsional vibrational frequency of the motor.

Abstract: A dynamic balancer for a laundry apparatus having a rotatable drum for receiving a clothes load. The rotatable drum has a horizontal geometric axis and is rotatably supported to rotate about its horizontal geometric axis. The rotatable drum includes a generally cylindrical outer wall defining the horizontal geometric axis, a first disk and a second disk. The first disk is provided for forming a first end wall of the drum and includes a balancing means including a plurality of concentric annular chambers. The second disk is provided for forming a second end wall of the drum, opposite the first end wall, and also includes a balancing means including a plurality of concentric annular chambers. The annular concentric chambers are partially filled with fluid for balancing the rotatable drum. In operation, the rotatable drum is subject to an out-of-balance mass as a result of uneven distribution of the clothes load within the drum.
