摘要： 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%.

摘要： A dynamoelectric machine includes a rotor having a rotor core and permanent magnets, and a stator having teeth. The permanent magnets are arranged in magnet sets. Each magnet set includes one or more of the permanent magnets. The rotor core has a cylindrical periphery and slits. Each of the slits is positioned radially between one of the magnet sets and the cylindrical periphery. Each tooth includes a tooth surface facing the cylindrical periphery. The tooth surface includes an inner portion extending substantially parallel to the cylindrical periphery of the rotor core, and beveled portions positioned on opposing sides of the inner portion of the tooth surface. An air gap between each beveled portion of the tooth surface and the cylindrical periphery of the rotor core is greater than an air gap between the inner portion of the tooth surface and the cylindrical periphery of the rotor core.
