Abstract

The aim of the study is to find a method to model electromagnetic devices which generate consequent magnetic leakage. Classical methods have proved to be efficient but time consuming. The method proposed in this paper is based on the magnetic moment method (MMM). An original methodology to obtain a simplified MMM model is described, adjusted with simple RNM model results. Besides the good accuracy, the simplicity of the model makes it possible to consider complicated studies with reasonable resolution times.
