摘要：
By incorporating the flux-mnemonic concept into the hybrid-field doubly-salient permanent-magnet (DSPM) motor structure, the resulting flux-mnemonic DSPM motor not only offers efficient online air-gap flux control, but can also flexibly operate as a DSPM motor when the PMs are magnetised or a switched reluctance (SR) motor when the PMs are demagnetised. The key of this study is to artfully utilise these modes of operation for the proposed flux-mnemonic DSPM motor drive. Namely, the motor drive works in the DSPM mode during open-circuit fault, and changes to the SR mode during short-circuit fault. Both computer simulation and experimental results are given to verify the validity of the proposed fault-tolerant flux-mnemonic DSPM motor drive.
