Zusammenfassung: | PROBLEM TO BE SOLVED: To make it possible to suppress deformation of an iron core and secure assembly accuracy of a stator even when winding is performed with an insulator being mounted onto the iron core in advance.SOLUTION: An insulator 3 includes a section that lies between an iron core 2 having a magnetic pole teeth section 22 that projects from a center of a back yoke section 21 to an inner diameter side and a coil 4 to be wound and covers the magnetic pole teeth section 22. The insulator 3 further includes an inner diameter side flange 31 and an outer diameter side flange 32 formed at positions corresponding to an inner diameter side and an outer diameter side of the iron core 2 for positioning the coil 4, respectively, and a groove section 33 formed on a face in contact with an axial direction end face of the magnetic pole teeth section 22.SELECTED DRAWING: Figure 5
【課題】インシュレータを予め鉄心に装着した状態で巻線しても、鉄心の変形を抑制することができ、ステータの組立精度を確保できるようにする。【解決手段】インシュレータ3は、バックヨーク部21の中央から内径側に突出した磁極ティース部22を有する鉄心2と巻回されるコイル4との間に介在し、磁極ティース部22を覆う部分を有しており、更にインシュレータ3は、コイル4を位置決めするために、鉄心2の内径側および外径側に相当する位置に形成された内径側鍔部31及び外径側鍔部32と、磁極ティース部22の軸方向端面と接する面に形成された溝部33を備えている。【選択図】図5 |
