Abstract

The authors present a method to obtain steady state performances of induction motors including space harmonics and saturation. The principle of the method consists on a spectral decomposition of the source field in the air gap, to compute each elementary problem corresponding to a harmonic order and then to use superposition to determine the total field. The saturation is included in an average sense using effective reluctivities. Computations are compared to experiments.
