ABSTRACT:
An improved multi-section rotor stack for a squirrel-cage sliding rotor type motor which includes a laminated stator stack, a laminated rotor stack, an axial shorting ring disposed on at least one end thereof, and an intermediate shorting ring interposed in the rotor stack at the other end thereof. The intermediate ring divides the rotor stack into a pair of sections of unequal length disposed respectively between the intermediate and axial shorting rings, and between the intermediate ring and the opposing end of the rotor stack relative to the axial shorting ring. The latter of the sections is shorter in axial length then the other and has a radial diameter which is greater, and increases the resultant axial force produced by the motor.
