To provide a motor of driving an electric vehicle capable of increasing an area where a stator core and a rotor are covered by a cooling medium, in the case of supplying the cooling medium from above to a drive motor of a vehicle.SOLUTION: In a motor 10, a cooling pipe 42 for flowing cooling oil is provided above a stator core 14, and from flow dividing pipes 52, 54, 64 and 66, the cooling oil is supplied near a top of a coil end. Further, from flow dividing pipes 48 and 50, the cooling oil is supplied to an upper portion of an outer peripheral surface of the stator core 14. The cooling oil supplied to the upper portion of the stator core 14 is guided to an end surface of the stator core 14 by a weir 16 and a projection 18 provided on the outer peripheral surface of the stator core 14 and is flowed down to a position in the lower side than an apex of the coil end.SELECTED DRAWING: Figure 1

    【課題】車両の駆動モータに冷却媒体を上方から供給する場合において、ステータコア及びロータが冷却媒体によって被覆される面積を増大させる。【解決手段】モータ10では、ステータコア14の上方に冷却オイルを流す冷却パイプ42が設けられており、分流パイプ52、54、64、66からはコイルエンドの頂点付近に冷却オイルが供給される。また、分流パイプ48、50からは、ステータコア14の外周面の上部に冷却オイルが供給される。ステータコア14の上部に供給された冷却オイルは、ステータコア14の外周面の設けられた堰16、突起部18によって、ステータコア14の端面に誘導され、コイルエンドの頂点よりも下側の位置に垂れ流される。【選択図】図1
