Abstract: A cooling system of an electric vehicle includes a cooling medium circulation path that circulates a cooling medium to an electrically powered drive unit of a vehicle, a heat exchange unit between the cooling medium and external air, a cooling medium circulation unit, a blower unit that blows air against the heat exchange unit, and a control unit that controls the cooling medium circulation unit and the blower unit, thus controlling cooling of the electrically powered drive unit. The control unit controls the cooling medium circulation unit and the blower unit in a first cooling mode, when a drive force for the vehicle is in a first operational region, and controls in a second cooling mode that provides a higher cooling capability than the first cooling mode, when the drive force for the vehicle is in a second operational region that is higher than the first operational region.

Abstract: To uniformly cool down armature windings along the circumferential direction of a stator in a generator motor. A generator motor includes a stator 1 fixed to the inner diameter side of a housing 18, a rotor 130 rotatably supported by bearings 5, and armature windings wound around the teeth of a stator core 110. Each of brackets 200 provided via the bearings 5 has a passage 201, 202 through which cooling oil flows and injection holes 204 which communicate with the passage and inject cooling oil at positions opposite to winding ends of the armature windings. Cooling oil is injected toward the winding ends of the armature windings from the injection holes 204 of the brackets 200 arranged on opposite axial sides of a shaft 6. In the flow rate distribution of the oil from the plurality of the injection holes 204, the flow rate of the oil from any of the injection holes 204 is set to be greater as the position of the injection hole 204 is higher above the level of the shaft 6. The arrangement pitch among the injection holes 204 provided on each of the brackets 200 is dense in a vertically upper portion of the bracket 200, and gradually sparser in a portion thereof closer to the level of shaft 6.
