  • Patent number: 9893579
    Abstract: 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.
