Abstract:
(EN) A motor according to an aspect of the present invention is provided with: a rotor having a shaft arranged along a central axis; a stator having a plurality of coils and radially facing the rotor with a gap therebetween; and a busbar unit arranged on one side of the stator in the axial direction. The busbar unit has: plate-shaped busbars electrically connected to the coils; and a busbar holder that holds the busbar. The busbars have: a plurality of busbar pieces, each of which is a unique member and a portion of which are embedded in the busbar holder; and a laser weld section for joining the busbar pieces to each other. The laser weld section is exposed to the outside of the busbar holder.
(FR) La présente invention concerne, selon un aspect : un rotor pourvu d'un arbre disposé le long d'un axe central; un stator pourvu d'une pluralité de bobines et faisant face radialement au rotor avec un espace entre eux; et une unité barre omnibus disposée sur un côté du stator dans la direction axiale. L'unité barre omnibus comprend : des barres omnibus en forme de plaque connectées électriquement aux bobines; et un support de barre omnibus qui maintient la barre omnibus. Les barres omnibus comprennent : une pluralité de pièces de barre omnibus, chacune étant un élément distinct, et une partie de chaque pièce étant intégrée dans le support de barre omnibus; et une section de soudure au laser destinée à relier les pièces de barre omnibus entre elles. La section de soudure au laser est découverte vers l'extérieur du support de barre omnibus.
(JA) 本発明のモータの一つの態様は、中心軸に沿って配置されたシャフトを有するロータと、複数のコイルを有し、ロータと径方向に隙間を介して対向するステータと、ステータの軸方向一方側に配置されるバスバーユニットと、を備える。バスバーユニットは、コイルと電気的に接続される板状のバスバーと、バスバーを保持するバスバーホルダと、を有する。バスバーは、互いに別部材であり、一部がバスバーホルダに埋め込まれる複数のバスバーピースと、バスバーピース同士を接合するレーザー溶接部と、を有する。レーザー溶接部は、バスバーホルダの外部に露出する。
