The invention provides a motor and an automobile, and relates to the technical field of automobile parts, the motor comprises a shell, a stator, a first oil cover and a second oil cover, the stator is located in the shell, the first oil cover and the second oil cover are arranged on the two axial sides of the stator respectively, a first oil cavity is formed between the first oil cover and one axial end face of the stator, and a second oil cavity is formed between the second oil cover and the other axial end face of the stator. A first oil cavity is formed between the first oil cover and the other axial end face of the stator, a second oil cavity is formed between the second oil cover and the other axial end face of the stator, a cooling runner penetrating in the axial direction is arranged in the stator, the two ends of the cooling runner are communicated with the first oil cavity and the second oil cavity respectively, a first oil inlet hole is formed in the first oil cover, and a second oil inlet hole and an oil outlet hole are formed in the second oil cover; the shell is provided with a first oil inlet communicated with the first oil inlet hole and a second oil inlet communicated with the second oil inlet hole. According to the motor, the windings at the two ends and the middle winding of the stator can be cooled in time, overall heat exchange of the stator is more uniform, the heat exchange cooling efficiency is higher, and the cooling effect is better.

    本发明提供了一种电机及汽车,涉及汽车零部件技术领域,所述电机包括壳体、定子、第一油罩及第二油罩,定子位于壳体内,第一油罩及第二油罩分别设于定子的轴向两侧,第一油罩与定子的一轴向端面之间形成第一油腔,第二油罩与定子的另一轴向端面之间形成第二油腔,定子的内部设有沿轴向贯穿的冷却流道,冷却流道的两端分别与第一油腔及第二油腔连通,第一油罩上设有第一进油孔,第二油罩上设有第二进油孔和出油孔,壳体上设有与第一进油孔相连通的第一进油口以及与第二进油孔相连通的第二进油口。本发明方案电机,能够实现对定子两端绕组及中部绕组的及时冷却,定子整体热交换更加均匀,热交换冷却效率更高,冷却效果更好。
