Description
前述した課題を解決するための、第一番目の発明に係る回転電機は、回転軸の外面に設けられたロータと、前記ロータの外面と所定の間隔を有して対向するように配設されてコアにコイルを巻き付けたステータと、前記コイルのコイルエンドに冷却液を送給する冷却液送給手段とを備えている回転電機において、前記回転軸の軸方向外側の前記コイルエンド端部のみに、前記回転軸の径方向外側に突出する鍔部が設けられると共に、前記冷却液送給手段が、前記冷却液を前記コイルエンドの前記鍔部よりも前記コア側へ送給するものであることを特徴とする。 A rotating electrical machine according to a first aspect of the present invention for solving the above-described problem is provided with a rotor provided on the outer surface of the rotating shaft and facing the outer surface of the rotor with a predetermined interval. In a rotating electrical machine comprising a stator with a coil wound around a core and a coolant supply means for supplying coolant to the coil end of the coil, only the end of the coil end on the axially outer side of the rotating shaft In addition, a flange protruding outward in the radial direction of the rotating shaft is provided, and the cooling liquid supply means supplies the cooling liquid to the core side from the flange of the coil end. It is characterized by that.
