Abstract:
A moisture resistant rotor sleeve includes a plurality of stacked laminations forming a sleeve having an outer periphery, an inner periphery, and spaces between adjacent laminations. The rotor sleeve also includes a sealant coupled to the inner periphery such that the outer periphery is free of sealant. The sealant seals the spaces to prevent fluid from traveling through the spaces of the sleeve between the inner periphery and the outer periphery.
