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.
