Abstract: Aiming at the single of the rotor rotation of the existing switched reluctance generator, the low utilization of wind energy and the problems of high noise and high vibration of generator, a new type of deflectable doublestators switched reluctance wind power generator was proposed. The inner and outer doublestators structures were applied to the generator. In order to achieve multidegree of freedom deflection, adapt to different wind directions and apply to all types of wind power generation, the hydraulic console was connected to both sides of the rotor. Through the calculation of the magnetothermosolid coupling field, the temperature rise, stress and vibration displacement were obtained. The results show that the twoway coupling analysis can better reflect the actual situation than oneway coupling analysis. In the multiphysical field coupling analysis, the stress is small, the vibration displacement belongs to nanometer level, and has little influence on the generator.

Key words: multiple physical field coupling; bidirectional coupling; vibration displacement; doublestators; switched reluctance generator
