One of the major issues is to develop a general analytical method which can generate automatically balanced winding solutions according to designers’ criteria and to qualify them by computing the winding factor, magnetomotive force harmonic content and self and mutual linkage inductances. This method implemented into a tool will permit to design electrical machine characterized by linkage and mutual inductances compatible with the future generation of multilevel and high frequency converter. The capabilities of the method, its basic principles, some examples and validations with Finite Elements Analyses (FEA) will be presented. Introduction Even if winding configurations have been widely studied, most of them are
