Abstract

Based on the irreversible demagnetization of the permanent magnet (PM) in Hybrid Excitation Flux Switching Machine (HEFSM), the demagnetization mechanism of PM for 12-slot 10-pole and 12-slot 14-pole at various temperatures for is initial and final design are analyzed for comparison. In order to remove excessive PM demagnetization, mitigation of PM in the final design of 12-slot 10-pole and 12-slot 14-pole HEFSM with several step is conducted. Upon removing the demagnetization area in PM, the PM size is restructured to keep the PM volume constant while keeping others parameter constant and zero demagnetization after mitigation process is achieved. It is found that PM demagnetization at the final design is reduced after several steps of optimization. The mitigation process shall also be for contributed to the development of the anti-demagnetization technology for Hybrid electric vehicles (HEV).
