英文摘要：

A novel stator-permanent-magnet double-rotor motor（SPM-DRM） was proposed. The SPM-DRM belongs to doubly salient motor which can simplify the middle rotor, effectively improve the mechanical strength of the middle rotor, and overcome the problem of PM heat dissipation with PM-DRM. The energy transference principle of SPM-DRM was presented for hybrid electric vehicles（HEV）. The model of SPM-DRM was established based on electromagnetic parameters obtained by finite element analysis. The multioperational modes of SPM-DRM were analyzed and simulated. A SPM-DRM prototype machine was fabricated and the test bench of the hybrid power system was implemented. The paper accomplished the experiments about some operational modes such as starting, pure electric driving and hybrid driving. The experimental results verify the validity of the theoretical analysis, the prototype design and the rationality of driving control strategy, which are helpful on further studying the SPM-DRM used for HEV.
