Zusammenfassung: | To provide a rotary electric machine for a vehicle capable of suppressing iron loss while maintaining coupling force for coupling a plurality of electromagnetic steel sheets to each other.SOLUTION: Due to press-fitting of a circular tubular member 22 into bolt holes 14d respectively formed in a plurality of electromagnetic steel plates 20, the plurality of electromagnetic steel plates 20 are joined together. Further, a stator core 14 is fastened to a casing 18 by screwing a fastening bolt 16 inserted through a circular tubular member 22 into the casing 18, such that the plurality of electromagnetic steel plates 20 are coupled to each other and the stator core 14 is fixed to the casing 18.SELECTED DRAWING: Figure 1
【課題】複数枚の電磁鋼板を相互に結合する結合力を維持させつつ鉄損を抑制することができる車両用回転電機を提供する。【解決手段】円管状部材22が複数枚の電磁鋼板20にそれぞれ形成されたボルト穴14dに圧入されることにより、複数枚の電磁鋼板20が相互に結合される。また、円管状部材22に挿通された締結ボルト16がケーシング18に螺合されることによって、ステータコア14がケーシング18に締結されることにより複数枚の電磁鋼板20が相互に結合されるとともに、ステータコア14がケーシング18に固定される。【選択図】図1 |
