1.Overview

To accurately obtaining the end-winding eddy current loss at high rotation speed, the influence of the magnetic field flux generated by the eddy current flow in every part of the machine cannot be ignored. Therefore, there is a need for considering the eddy currents of multiple parts simultaneously. However, the larger sizes of the model and its calculation times can be an obstacle to performing such analysis. For this, the use of a highly parallel processing environments is necessary. This allowed obtaining accurately the eddy currents at every location of the machine. Furthermore, we confirmed that the obtained eddy current loss improved the accuracy of both the loss values and the efficiency map of the machine. Additionally, the mesh modelling for this kind of eddy current calculation will be discussed.
