  • Efficient axial airgap electric machine having a frontiron
    Patent number: 7105975
    Abstract: A rotating, dynamoelectric machine, such as an electric motor, a generator, or a regenerative motor, comprises a stator assembly that includes a backiron section, a plurality of stator tooth sections, and a frontiron. The dynamoelectric machine has an axial airgap-type configuration. In addition, the electric machine has a high pole count that operates at high commutating frequencies, with high efficiency, high power density and reduced heating in the rotor. Low-loss materials employed in the dynamoelectric machine include amorphous metals, nanocrystalline metals, optimized Fe-based alloys, and optimized grain-oriented Fe-based materials or non-grain-oriented Fe-based materials.

  • Rotor reluctance notch for cogging control
    Patent number: 4504755
    Abstract: In an electric motor of the type having a permanent magnet rotor which is subject to cogging torque, a plurality of skewed reluctance notches are cut in the outer diameter of the rotor laminations. The rotor laminations have first and second sets of axial openings which are filled respectively with rare earth magnet material and non-ferrous casting material.
