Abstract
A rotor for an induction motor has a plurality of central laminations defining a central bore extending along an axis. End laminations are at each axial end of the central laminations. Metal is within gaps formed between lamination teeth. The end laminations have teeth extending radially outwardly from a central ring portion. A bore is formed in a face of the end laminations facing outwardly, and adjacent to where the teeth connect into the central ring portion. A motor and method are also described.
