Abstract

An electric motor comprises a shaft, an interior magnet rotor core comprising a central bore and a pair of opposing ends faces, and at least one resilient structure inserted within the central bore between the pair of opposing end faces. The at least one resilient component is inserted within the central bore between the pair of opposing end faces such that the at least one resilient component does not extend beyond one of the opposing end faces. The resilient component comprises an outer rigid structure inserted within the central bore, a resilient component inserted within the outer rigid structure, and an inner rigid structure inserted within the resilient component, wherein the shaft is inserted through the inner rigid structure.
