Original Abstract

Accurate loss calculation is an important part of the machine design, which can have significant influence on the predicted operating temperature, especially in the high-speed applications. In this paper, the calculation method of additional copper losses is demonstrated with an example of high-speed induction machine. The additional copper losses are studied using finite element analysis for twisted and non-twisted stator windings. In the proposed study, only one coil is modeled with strands to optimize computational resources. Influence of an accurate determination of the end winding leakage inductance on additional loss is presented. Proposed method of the analysis can be implemented for loss estimation of various high-speed electrical machines.
