Summary: | To provide a stator and a rotary electric machine which improve a heat transfer property from a coil to teeth.SOLUTION: A stator comprises: a stator core 20 having teeth 23 extending along a radial direction; a bobbin 30 which covers the teeth 23; and a coil 40 which is wound around the bobbin 30. The bobbin 30 comprises: a first covering part 31 which covers an end surface in an axial direction of the teeth 23; and a second covering part 32 which covers an end surface 25 in a circumferential direction of the teeth 23. The first covering part 31 comprises an irregular guide part 33 which guides a lead wire 41 forming the coil 40. Then, the second covering part 32 has a plane part 37 from one end in the axial direction over the other end in the axial direction on a front surface of the second covering part 32.SELECTED DRAWING: Figure 3
【課題】コイルからティースへの伝熱性を向上させることを可能としたステータ及び回転電機を提供する。【解決手段】ステータは、径方向に沿って延在するティース23を有するステータコア20と、ティース23を被覆するボビン30と、ボビン30に巻回されているコイル40と、を備える。ボビン30は、ティース23の軸方向端面を被覆する第1被覆部31と、ティース23の周方向端面25を被覆する第2被覆部32と、を備える。第1被覆部31は、コイル40を形成する導線41をガイドする凹凸状のガイド部33を有している。そして、第2被覆部32は、第2被覆部32の表面における軸方向一端から軸方向他端にわたって平面部37を有している。【選択図】図3 |
