Description
Claims (6)
- 回転子に対する軸線方向一端側に該回転子と一体回転可能なファンが設けられ、固定子を収容する固定子枠の前記軸線方向一端側には前記ファンを収容するファンケースが接合され、前記ファンケースには、外部から前記ファンに向かって空気を導入するための外気導入口と、前記ファンの外周側に導かれた空気中の塵埃を外部に排出するための塵埃排出口とが設けられた車両用電動機において、
前記ファンケースには、前記固定子枠の内周面よりも半径方向外周側に膨らんだ内周面を有する拡大部が設けられ、前記塵埃排出口の少なくとも一部が前記拡大部の内周面に開口している車両用電動機。 - 前記ファンケースには、前記固定子枠に対して前記軸線方向に突き合わせて接合される接合部が設けられ、前記接合部は前記拡大部の内周面よりも半径方向中心側に突出し、それにより前記ファンケースには前記拡大部の内周面から前記接合部に向かって内径が漸次減少する縮径部が設けられている請求項1の車両用電動機。
- 前記接合部は、前記固定子枠の内周面よりも半径方向中心側に突出している請求項2の車両用電動機。
- 前記固定子枠内には、前記ファンにより導かれた空気が流入する冷却通路が前記固定子の外周側に形成され、前記拡大部の内周面が、前記冷却通路よりも半径方向外周側に膨らんでいる請求項1~3のいずれか一項の車両用電動機。
- 前記固定子には、空気が流入可能な風穴が設けられ、前記風穴が、前記冷却通路の少なくとも一部として設けられている請求項4の車両用電動機。
- 前記固定子枠には、前記風穴との段差を減少させるリングが設けられている請求項5の車両用電動機。
