Abstract：This paper proposes a new flux-switching permanent-magnet double-rotor(FSPM-DR) machine for hybrid electric vehicles. The key is to integrate the concept of double-rotor machine into the flux-switching permanent-magnet machine, and thus the resulting machine can meet hybrid electric vehicle’s(HEV) demand of small amount and steady running for machine’s high torque density and low torque ripple. The machine topology and operation principle are presented. By using the finite element method(FEM), the corresponding electromagnetic performances are analyzed. The simulation results demonstrate the rationality of machine’s design. The test starting speed and current waveforms show good dynamic response performance, and the test no-load back electromotive force results on the principle prototype also verify the validity of machine’s design, which means that the FSPM-DR structure machine can effectively improve torque density and decrease torque ripple, and can meet power demand for HEVs after its rational design.

Key words： Flux switching permanent magnet machine(FSPM) double-rotor machine design hybrid electric vehicle(HEV) electromagnetic performance finite element method(FEM)
