Abstract

In this paper iron loss analysis of the permanent magnet motor considering anisotropy of magnetic material is carried out. The magnetic material can be measured using vector quantity technique. Non-oriented silicon steel sheets for the iron core material have the anisotropy. Therefore, it is necessary to carry out the analysis considering the anisotropy of the magnetic material. A magnetic field analysis, which considers the anisotropy by combining finite element method with the E&S (Enokizono and Soda) model, is considered
