Abstract

In order to improve the efficiency and flexibility of the switched reluctance generator, a novel deflection double stator switched reluctance generator was proposed based on the structural characteristics of the switched reluctance motor. The magnetic flux of the generator was analyzed by magnetic circuit analysis method, obtaining the matrix expression of the average magnetic flux of the stator and rotor. Then it is transiently simulated by electromagnetic analysis software to calculate the radial and tangential components of the core magnetic density of the generator. At the same time, the calculation results of the finite element method are compared with the results of the analysis method to verify the correctness of the analytical method model. Finally, the calculated magnetic density component is transformed by Fourier transformation to obtain the corresponding harmonic analysis. And the ellipse method was used to calculate the iron loss of the generator, compared with the experimental results to illuminate the accuracy of the iron loss calculation scheme.
