Abstract
Description
本実施形態の回転電機1は、車両用モータとして用いられるものであって、図1に示すように、ハウジング10と、回転軸13と、回転子14と、固定子コア30及び固定子巻線40を有する固定子20と、を備えている。
実施形態2の回転電機1の固定子20Aは、実施形態1のものと基本的構成が同じであるが、分割コア32Aを構成する2種類の第1鋼板35及び第2鋼板36の配置位置が実施形態1の分割コア32と異なる。よって、実施形態1の固定子20と共通する部材については詳しい説明は省略し、異なる点及び重要な点について説明する。なお、実施形態1と共通する部材は同じ符号を用いる。
本発明は、上記の実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々変更することが可能である。
Claims (4)
- 周方向に分割された複数の分割コア(32,32A,32B)を円環状に組み付けてなる固定子コア(30)と、前記固定子コアの外周に嵌合固定された外筒(37)と、前記固定子コアに巻装された固定子巻線(40)と、を備え、前記固定子コアを誘導加熱して硬化させた熱硬化性樹脂により前記固定子巻線が前記固定子コアに固定されている回転電機の固定子において、
