Abstract

A model reduction method for finite element analysis such as the zooming analysis is conducted to calculate the AC copper loss of high speed electric machines. In this paper, the accuracy of the zooming method is validated by comparison with thorough analysis and the calculation speed in the zooming analysis is found to increase by 7.8 times that of thorough analysis.
