Summary:PROBLEM TO BE SOLVED: To provide a rotary machine which can improve cooling efficiency of the stator, while reducing windage loss between respective salient poles of the rotor.SOLUTION: A rotary machine 1 includes a rotor 2 having multiple salient poles 6, a stator 3 arranged to surround the rotor 2, and having multiple salient poles 7, multiple coils 8 wound around respective salient poles 7, and a housing 4 fixed to the outer peripheral surface of the stator 3, and housing the rotor 2 and stator 3. Between the housing 4 and stator 3, a coolant passage 10 for passing the coolant in the axial direction of the rotor 2 is provided, and a cover 11 covering the space S between respective salient poles 6 is arranged on one end side of the rotor 2.SELECTED DRAWING: Figure 2 【課題】ロータの各突極部間の風損を低減しつつ、ステータの冷却効率を向上させることができる回転機を提供する。【解決手段】回転機１は、複数の突極部６を有するロータ２と、ロータ２を取り囲むように配置され、複数の突極部７を有するステータ３と、各突極部７にそれぞれ巻回された複数のコイル８と、ステータ３の外周面に固定され、ロータ２及びステータ３を収容するハウジング４とを備え、ハウジング４とステータ３との間には、ロータ２の軸方向に冷媒が流れる冷媒流路１０が設けられており、ロータ２の一端側には、各突極部６間のスペースＳを覆うカバー１１が配置されている。【選択図】図２
