The purpose of the present invention is to provide a rotating electrical machine in which a cooling structure is simplified and an increase in production cost is suppressed. In a rotary electric machine, the rotation axis of a rotor shaft (26) is disposed at a predetermined angle with respect to the horizontal axis. This rotating electrical machine is provided with: an upper flow path (252) which is formed on the upper side of a stator core (23a) and through which a liquid refrigerant flows; a lower flow path (255) formed on the lower side of the stator core (23a); and a groove flow path (257) that connects the upper flow path (252) and the lower flow path (255). The upper flow path (252) is formed by the housing (25), the upper end surface of the stator core (23a), and an upper flow path forming body (251) connecting the housing (25) and the upper end surface on the gap (G) side of the stator core (23a). At least a part of the end surface of the groove flow path (257) on the gap (G) side is open.
本发明的目的在于提供一种简化了冷却用的结构、抑制了生产成本的增加的旋转电机。本发明的旋转电机中,转子轴(26)的旋转轴是以相对于水平轴而具有规定角度的方式进行配置。本发明的旋转电机具备:上侧流路(252),其形成于定子铁芯(23a)的上侧,供液状制冷剂流动;下侧流路(255),其形成于定子铁芯(23a)的下侧;以及槽流路(257),其连通上侧流路(252)及下侧流路(255)。上侧流路(252)由罩壳(25)、定子铁芯(23a)的上端面、以及连接罩壳(25)与定子铁芯(23a)的空隙(G)侧的上端面的上侧流路形成体(251)形成。槽流路(257)的空隙(G)侧的端面的至少一部分开口。
