Abstract
A rotor lamination for a permanent magnet synchronous machine. The rotor lamination can be used for a two, four or eight pole synchronous machine. The orientation of the permanent magnets determines the number of poles of the machine. The lamination can also include openings adapted to contain conductors used to bring a synchronous motor up to synchronous speed as an induction motor.
