Summary:To prevent deformation of a coil end at low cost by attaining downsizing of the coil end.SOLUTION: A coil end 13a at the side of a lower insulator 8a protrudes from an inner peripheral terminal position of teeth 10 to an inner peripheral side, and a coil end 13b at the side of an upper insulator 8b is prevented from protruding from the inner peripheral terminal position of the teeth 10 to the inner peripheral side. A terminal block 14 comprises a cylindrical wall 14b defining a rotor with the coil end 13b at the side of the upper insulator 8b, and sheet-like varnish 18 for applying varnish processing to the coil end 13b.SELECTED DRAWING: Figure 19 【課題】巻線エンド部の小型化を図り、巻線エンド部の変形を安価に防止できること。【解決手段】下部インシュレータ８ａ側の巻線エンド部１３ａは、歯部１０の内周側の端部位置より内周側に突出し、上部インシュレータ８ｂ側の巻線エンド部１３ｂは、歯部１０の内周側の端部位置より内周側に突出しないようにする。端子台１４は、上部インシュレータ８ｂ側の巻線エンド部１３ｂと回転子を画成する円筒状の壁部１４ｂと、巻線エンド部１３ｂにワニス処理を施すシート状のワニス１８と、を備える。【選択図】図１９
