The shrink ring is one of the critical components on the motor rotor. It is shrink-fitted onto the short-circuit ring. Subjected to interference fit force, centrifugal force from itself and the winding ends, bending stress and other loads, it bears high superimposed stress. It features high strength, high plasticity, high toughness, non-magnetic property and minimum residual stress.
