ABSTRACT:
The invention relates generally to an electric device, such as an electric motor, a generator, or a regenerative motor, having a wound stator core made from advanced low-loss material. In preferred embodiments, the electric device is an axial airgap-type configuration. The invention provides an electric device having a high pole count that operates at high commutating frequencies, with high efficiency and high torque and power densities. Advanced low-loss materials exploited by the present invention include amorphous metals, nanocrystalline metals, and optimized Fe-based alloys.
