Abstract：Switched reluctance machine has the advantages of high reliability, low cost, high efficiency and wide platform. However, the inherent disadvantages of the switched reluctance machine, such as high torque ripple and low power density, seriously limit its application and promotion of in the field of electric vehicles. In order to solve the above problems, a new structure of double stator switched reluctance machine with field decoupling is proposed in this paper. The internal and external stators adopt U-shaped block structure. By optimizing the polarity distribution of the internal and external stator magnetic fields, the internal and external stator magnetic fields are decoupled. On this basis, the torque ripple is reduced by staggering the internal and external teeth of the rotor at a certain mechanical angle. This paper first introduces the working principle and design method of the new machine, and then compares the static and dynamic performance of two different rotor poles. Finally, a prototype of a 4-phase 16/18/16 structure is manufactured. The working principle is verified by experiments, which lays a theoretical foundation for the popularization and application of the new machine in the field of electric vehicle drive system.
