ABSTRACT:
A rotor assembly for mounting a rotor to a motor shaft having a rotor with a centrally positioned central bore, the diameter of which is slightly larger than a diameter of the motor shaft, a first stepped bore intersecting the central bore and being aligned along a first axis of the rotor, and a second stepped bore also intersecting the central bore and being aligned along a second axis of the rotor. A first cam fastener is disposed within the first stepped bore, and a second cam fastener is disposed within the second stepped bore. Upon rotating the first and second cam fasteners, they engage the motor shaft thereby securely clamping the rotor to the motor shaft.
