Abstract
A rotor for an electric machine may include a rotor hub, a plurality of permanent magnets disposed about the rotor hub, a first sleeve circumjacent the plurality of permanent magnets, and a second sleeve. The second sleeve may be formed from a metal tape wrapped over the first sleeve. The second sleeve may be bonded to first and second end rings disposed at adjacent ends of the rotor hub. The metal tape may be applied in tension and may wrapped to form butt laps over the first sleeve. The metal tape may be corrosion resistant. Further, the second sleeve formed from the metal tape may protect the rotor from erosion and abrasion from fluid passing over the rotor.
