Parameters calculation and optimized design for brushless doubly-fed reluctance machine

On the basis of the principle of brushless doubly-fed machine (BDFM), this paper proposes a Radial laminated reluctance rotor with non-magnetic bridge. When concerning optimal desinging of this kind of rotor, this paper indroduce Taguchi mothod which is very mature in optimal calculation field abroad, but is rarely applied at home. By using this method, four levels of the five rotor shape parameters are grouped, and 16 sets of data are selected to analyzed. In the end, a set of peremeters are chosen with the goal of minimizing the torque ripple.
