Abstract

According to several papers, the main flux path of an induction machine is saturated not only due to the magnetizing current. Measurements and related parameter estimations show the influence of the torque building current component on the magnetization curves. The paper at hand presents 2D FEM calculations carried out in order to support and possibly verify the experimental investigations by means of a numerical approach. The outcome of the FEM calculations shows a high level of agreement with the results obtained by measurement.
