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.
