図1および図2を参照して、ステータ1は、ステータ巻線を有する環状のステータコア501を有し、このステータコア501が樹脂封止されるとともに、樹脂封止されたステータコア501が冷却ジャケットと呼ばれるケース内に収容されている。冷却ジャケットは、ステータコア501の外側に位置する締結リング100、ステータコア501の外側に位置する内側リング200、および、ステータコア501の両端のコイルエンドに位置するコイルエンドカバー300,400から構成されている。
図3に示すように、回転電機の回転軸芯に対してステータコア501の中心位置A1が一致するように、ステータコア501を中心位置決め用治具700に位置決め固定する。中心位置決め用治具700には、ステータコア501の下端を収容する環状の凹部領域701が設けられるとともに、ステータコア501の内周面側からステータコア501を半径方向外方に向かって押圧する内径保持部材702を備えている。内径保持部材702によりステータコア501が外側に向かって押圧されることで、ステータコア501の位置決めが完了する。
一方、図4に示すように、締結リング100は加熱装置600により加熱し、その内径を拡大させた状態に保持する。内径が拡大した締結リング100の内側にステータコア501を収容する。その後、締結リング100を冷却させることで、締結リング100の内径が収縮する。その結果、締結リング100は、ステータコア501の外周面に固定される。
次に、図5を参照して、ステータコア501が中心位置決め用治具700に固定された状態で、中心位置A1を位置決め基準にして、ステータコア501の締結リング100に設けられたフランジ部110にドリルD1を用いた穴あけ加工により固定用穴110hを形成する。図6および図7に示すように、固定用穴110hの位置は、中心位置A1を基準にしてR1の距離に開口される。平面的には、中心位置A1を基準にして所定の中心角度ピッチ(たとえば、120°ピッチ)で開口される。
このように、実施の形態1におけるステータおよびステータの製造方法においては、回転電機の回転軸芯に対してステータコア501の中心位置A1が一致するように、ステータコア501を中心位置決め用治具700に位置決め固定するステップと、ステータコア501が中心位置決め用治具700に固定された状態で、中心位置A1を位置決め基準にして、ステータコア501の締結リング100に設けられたフランジ部110に固定用穴110hを形成するステップとを備えている。
図8から図10を参照して、本実施の形態におけるステータおよびその製造方法について以下説明する。本実施の形態におけるステータにおいては、締結リング100に設けられたフランジ部110に設けられる固定用穴110hとして、フランジ部110に予め設けられた下穴110mに対して、穴あきリベット810の固定により形成された穴を有していることを特徴としている。以下、固定用穴110hの成形ステップについて説明する。なお、締結リング100をステータコア501に固定するまでの工程は、上記実施の形態1と同じである。
図11から図13を参照して、本実施の形態におけるステータおよびその製造方法について以下説明する。本実施の形態におけるステータにおいては、締結リング100に設けられたフランジ部110に設けられる固定用穴110hとして、フランジ部110に対してプレス穴あけ加工により形成された穴を有していることを特徴としている。以下、固定用穴110hの成形ステップについて説明する。なお、締結リング100をステータコア501に固定するまでの工程は、上記実施の形態1と同じである。
上記実施の形態1~3におけるステータの製造方法においては、ステータコアに対する締結リング100の固定工程を終えた後に、固定用穴110hを形成していることから、締結リング100の加熱・冷却によるズレの発生の影響を受けることなく、中心位置A1を基準とした正確な位置に、固定用穴110hを形成することを可能としている。
