ABSTRACT:
A rotor assembly for an air handler motor includes a rotor core and a rotor insert comprising at least two elements fixedly attached to the shaft of the motor. Said rotor elements have non-circular axial outer surfaces which fit in a hole in the rotor core. The inserts are sealed to the core by an elastomeric seal, which functions to prevent axial movement of the rotor core along the shaft, transmit torque and damp vibrations resulting from the magnetic field employed to power the rotor, thus suppressing noise.
