Finite element analysis of high-speed solid rotor induction machine with copper cage

Abstract

High-speed electric machines are design with respect to mechanical, electromagnetic and thermal requirements. For successful thermal and mechanical design relevant input data from electromagnetic design stage are required. One of the most important data are related to power loss distribution inside the electric machine. That is due to the fact that power losses represent requirement on cooling method and mechanical design. This paper is dealing with electromagnetic calculation of high-speed solid induction machine with copper cage. For this purpose electromagnetic model of this machine has been developed and analyzed. All calculation are performed by using of time-step, 2D finite element analysis. All obtained results are presented and discussed.
