Abstract [en]

Tooth ripple losses in solid salient poles are calculated with analytical and semi-empirical methods. A numerical method based on the finite element method is presented in this article. The distribution of the eddy currents induced by the tooth ripple is obtained with this new method. The traditional analytic approach is based on some assumptions on the eddy current losses distribution that are finally verified with the Finite Element Method simulations presented. Analytic solutions of tooth ripple losses are only applicable to distributed windings with a homogeneous slot pitch while the method presented is applicable both to distributed and concentrated windings.
