摘要： A motor cooling device having good cooling performance, which is adapted to promote heat transfer between a coil end and a coil end cover even if the flowing amount of oil is small. A heat of a stator is withdrawn by the oil flowing around the coil end. For this purpose, the motor cooling device comprises a flow path formed between an outer face of the coil end and an inner face of the coil end cover, and a flow rate adjusting unit for changing a cross-sectional area of the flow path by moving the coil end cover toward the coil end or away from the coil end. The flow rate adjusting unit widens the cross-sectional area of the flow path in case a feeding amount of the oil to the flow path is relatively large, and narrows the cross-sectional area of the flow path in case a feeding amount of the oil to the flow path is relatively small.
摘要翻译：具有良好的冷却性能的电动机冷却装置，其适用于促进线圈端部和线圈端盖之间的热传递，即使油的流量少。定子的热量由绕线圈端部流动的油抽出。为此，电动机冷却装置包括在线圈端的外表面和线圈端盖的内表面之间形成的流路，以及流量调节单元，用于通过移动来改变流路的横截面积线圈端盖朝向线圈端或远离线圈端。在流向流路的油的供给量相对较大的情况下，流量调节单元使流路的截面积变宽，在油的供给量的情况下，使流路的截面积变窄到流路比较小。
