Abstract
A method of manufacturing dynamoelectric machines includes producing a first plurality and a second plurality of stator and rotor laminations using a die press, forming a first rotor from the first plurality of rotor laminations, and forming a second rotor from the second plurality of rotor laminations. The first plurality and the second plurality of stator laminations have the same inner and outer diameters. The first plurality and the second plurality of rotor laminations have the same inner and outer diameters. The first plurality of rotor laminations have a first magnet slot configuration and the second plurality of rotor laminations have a second magnet slot configuration different than the first magnet slot configuration. The first rotor and the second rotor may have the same or different stack heights. Preferably, a ratio of each stator lamination's inner diameter to outer diameter is at least 60%.
