A rotating electrical machine is provided with: a stator having a stator core around which a plurality of coils are wound; a rotor rotatably supported by the stator across a predetermined gap; a rotor housing for holding the rotor; and a first bearing (201) and a second bearing (202) for rotatably supporting the rotor housing. A rotating electrical machine is provided with: a first flow path forming body (501) that forms a first flow path (501s) through which a refrigerant flows to a coil end section (601) protruding from a stator core; a first housing part (401) that forms a housing space (201s) for the first bearing, is connected to the first flow path of the first flow path forming body, and fills the housing space with a refrigerant; a second flow path forming body (502) that forms a second flow path (502s) through which the refrigerant flows to a coil end part (602) disposed on the opposite side in the axial direction with respect to the coil end part; and a second housing part (402) which is connected with a second flow path of a second flow path forming body forming an accommodating space (202s) of the second bearing and is filled with a refrigerant.
旋转电机具备具有卷绕有多个线圈的定子铁芯的定子、隔着规定的间隙旋转自如地支承于定子的转子、保持转子的转子壳体、以及使转子壳体旋转自如地支承该转子壳体的第1轴承(201)和第2轴承(202),旋转电机具备:形成向从定子铁芯突出的线圈末端部(601)流通制冷剂的第1流路(501s)的第1流路形成体(501);形成第1轴承的收容空间(201s)、并且与第1流路形成体的第1流路相连且利用制冷剂填充该收容空间的第1壳体部(401);形成向相对于上述线圈末端部配置在轴向相反一侧的线圈末端部(602)流通制冷剂的第2流路(502s)的第2流路形成体(502);以及形成第2轴承的收容空间(202s)的第2流路形成体的第2流路相连且利用制冷剂填充该收容空间的第2壳体部(402)。
