Patent ID: 8400029

Claim:
A rotating electrical machine, comprising: a stator that includes a cylindrical stator core and a stator winding wire wound around the stator core; a rotor disposed facing the stator via a gap; and a plurality of cooling medium paths, each having an inflow port through which a cooling medium flows in and an outflow port through which a cooling medium flows out, the cooling medium paths being provided in the stator, extending in a direction of a central axis of the stator core; wherein each of the cooling medium paths is inclined relative to the central axis of the stator core, the cooling medium paths include at least one first cooling medium path and at least one second cooling medium path that flow the cooling medium in opposite directions to each other, the stator core is provided at one side thereof in the axial direction with the or each inflow port of one of the at least one first cooling medium path and the at least one second cooling medium path and with the or each outflow port of the other of the at least one first cooling medium path and the at least one second cooling medium path, and the or each inflow port provided at the one side of the stator core in the axial direction are disposed on a position higher in a vertical direction than the or each outflow port corresponding thereto provided at the other side of the stator core in the axial direction.
