The invention relates to the technical field of motors, in particular to an immersion liquid cooling motor, a power assembly and a vehicle. A stator of the motor comprises a stator iron core, a stator winding and an annular injection molding body which is integrally formed through injection molding, the annular injection molding body comprises a plurality of embedded sections and an exposed section, the exposed section and the embedded sections are adjacently arranged in the axial direction of the motor, each embedded section is used for being embedded into a winding groove in the radial direction of the motor, and the exposed section is used for being embedded into the winding groove in the radial direction of the motor. One exposed section is exposed out of one axial end face in the axial direction of the motor, one exposed section is used for surrounding one motor end cover, one stator sleeve and one axial end face form one containing cavity, and one containing cavity is used for containing cooling liquid to immerse one end of the stator winding. The annular injection molding body is fixedly connected with the motor end cover of the motor shell, so that the accommodating cavity can be formed between one end part of the stator and the shell, the end winding of the stator winding is subjected to immersion liquid cooling, the cooling effect on the stator winding is enhanced, and the power of the motor is improved.

    本申请涉及电机技术领域,尤其涉及一种浸没液冷的电机、动力总成及车辆。该电机的定子包括定子铁芯、定子绕组和一体式注塑成型的环形注塑体,环形注塑体包括多个嵌入段和一个露出段,沿所述电机的轴向一个露出段和所述多个嵌入段相邻排列,每个嵌入段用于沿电机的径向嵌入一个绕组槽,一个露出段沿电机的轴向露出于一个轴向端面,一个露出段用于围合一个电机端盖、一个定子套筒及一个轴向端面形成一个容纳腔,一个容纳腔用于容纳冷却液浸没定子绕组的一端。环形注塑体与电机壳体的电机端盖连接固定,可以使定子的一个端部与壳体之间形成容纳腔,对定子绕组端部绕组进行浸没液冷,增强对定子绕组的冷却效果,提高电机的功率。
