Abstract
Description
1)この電源供給部材の製作において材料歩留まりが多く、きわめて不経済である。
2)リング状をなす各相毎の電源供給部材と絶縁部材を交互に積層して、つまり、垂直に絶縁距離をおいて積層してハウジング本体の収納溝内に収容された構成であるため、ハウジング本体は厚みが厚くなり、モータに対する組み付け方向の寸法が大型化する。
3)電源供給部材と絶縁部材の積層により金型奥行きが深くなるため、成形時のインサート部品設置が困難である。
4)各相の電源供給部材のリード線コネクタ数が多いため、ハウジング本体から突出するリード線コネクタ数が多く、モータコイルとの接合による組み立て工数が多く、組立作業が面倒である、
等の課題があった。
