| Abstract: | Based on a novel fourphase fluxconcentrating transverse flux PM machine with passive rotor, taking the 3Dfinite element method as a powerful tool, using the 4/2 coordinate transforation, the dqaxis inductances were calculated and analyzed detailedly. On this basis, the torques were calculated of different current angle and the calculated results were compared with the data by 3D finite element. Finally the results of variation trend of dqaxis inductance and torque were presented. The research results were helpful to the design and to the method of control of the transverse flux PM machine. |
