Abstract

　高効率で、低振動・低騒音な永久磁石同期電動機を提供することを目的とする。固定子３０は、隣接するスロット３間に形成された磁極歯部２を備えた固定子鉄心１と、固定子鉄心１のスロット３に配置される固定子巻線４とを有し、回転子４０は、回転子鉄心５と、複数の磁石挿入孔８と、磁石挿入孔８に挿入される永久磁石７と、磁石挿入孔８の外周側の回転子鉄心５に形成される複数のスリット６とを有し、スリット６の内、回転子鉄心１の磁極中心付近の複数のスリット６は、永久磁石７から発する磁束が回転子鉄心１の外側で収束する方向に向くように配置されると共に、回転子鉄心５の極間部付近のスリット６は、回転子鉄心５の磁極中心付近の複数のスリット６と異なる方向に向くように配置されることを特徴とする。
