Optimization design on salient pole rotor of BDFRM using the Taguchi method

In this paper, it proposed a novel test method, which combined the Taguchi method with the finite element analysis, to optimize the average electromagnetic torque and coupling ability of a salient pole rotor of BDFRM. According to practical situations, four controllable factors´ level, such as the air-gap length, rotor pole arc coefficient, lateral radius, the diameter of the shaft are tested by the Orthogonal Array. With the analysis of signal to noise ratio, a salient pole rotor of BDFRM is designed by using the optimal combination of parameters.
