Abstract: Substantial efforts are currently underway around the world to develop environmentally friendly transportation, of which the development of electric vehicles plays a key role. Statorpermanent magnet (PM) machines have attracted wide attention due to the robust rotor structure and comparable performance in terms of normal permanent magnet synchronous machines (PMSM) having magnets in the rotor. In particular, the flux-switching machines feature a particular magnetic circuit configuration that favors Dy-free magnets in terms of demagnetization risk, and as a result, the cost of the motor can be reduced considerably. With focus on applications in electric vehicles (EVs) and hybrid electric vehicles (HEVs), this paper reviews the latest developments of PM flux switching machines, with particular emphasis on the novel machine topologies and control strategies.
