نویسندگان
چکیده
This paper deals with characteristics of interior permanent magnet synchronous motor considering anisotropic characteristics of electrical steel sheets. Motor characteristics of back electro-motive force (EMF), d-q axis inductances, and core loss are calculated by FEA considering anisotropy of electrical steel sheets and compared to the results from experiment and general FEA; using single material data of isotropic electrical steel sheets for the entire core region. An interior permanent magnet motor is fabricated and analysis results are verified by experiments. In the verification, 11% higher back EMF than experiment is calculated by general FEA while 2% higher back EMF by considering anisotropy of material. For the fabrication, rotational stacking is not applied.
