| Zusammenfassung: | In order to efficiently cool a stator and rotor of a rotating electrical machine, cooling oil is supplied by a pump in a pressurized state to a first reservoir portion provided in an upper portion inside a housing, and after the cooling oil is ejected from the first reservoir portion, the cooling oil is guided to a stator coil end cooling structure, and to a rotor bearing and rotor core cooling structure, using the weight of the cooling oil itself. |
