The purpose of a Multiphysics Analysis is the modeling of complex physical systems where different kinds of physical effects act simultaneously. We would like to predict the behavior of a machine with the least number of neglected effects. Nowadays more Finite Element Method (FEM) based simulation software are readily available to study the physics of an electrical machine. Although, there are no standardized solutions that would fit every kind of electric motor analysis. In this paper we will present a method how to go through step-by-step on the different physical phenomena of an electrical machine and therefore analyze the different design and working aspects.
