The rotor eccentricity unbalances the magnetic force and thus increases the mechanical loss. Furthermore, a circulating current generated result in an increase of electric power loss in the permanent magnet synchronous motor with three-phase parallel winding of the stator coils. Therefore, we presented that the flux barrier rotor is effective to reduce the harmful effect of the rotor eccentricity.本誌: 電気学会論文誌D（産業応用部門誌） Vol.131 No.8 （2011） 特集：IPEC-Sapporo 2010本誌掲載ページ: 1029-1035 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/131/8/131_8_1029/_article/-char/ja/ Show more
