Title:
STATOR COIL ARRANGEMENT FOR AN AXIAL AIRGAP ELECTRIC DEVICE INCLUDING LOW-LOSS MATERIALS
Document Type and Number:
WIPO Patent Application WO2005043714
Kind Code:
A3
Abstract:
A dynamoelectric, rotating electric machine includes a stator (20) assembly that includes stacked stator coil windings (50). The machine is preferably a polyphase, axial airgap device. Improved slot filling results from the stacked stator coil configuration. Device performance capability is thereby increased. The stator assembly of the electric device has a magnetic core (24) made from low loss, high frequency material. A high pole count permits the electrical device to operate at high commutating frequencies, with high efficiency, high power density and improved performance characteristics. Low-loss materials incorporated by the device include amorphous metals, nanocrystalline metals, optimized Si-Fe alloys, grain-oriented Fe-based materials or non-grain-oriented Fe-based materials.
