The invention relates to the technical field of motors, in particular to a winding immersion liquid cooling motor, a power assembly and a vehicle. The motor comprises a stator core, a stator winding, an annular cover plate and an injection molding part which is integrally formed through injection molding. The plurality of winding grooves of the stator core are used for fixing the injection molding part and the stator winding, and the injection molding part comprises a plurality of embedded sections and an exposed section. Each embedded section is embedded into one winding groove in the axial direction of the motor, one exposed section covers one axial end face of the stator iron core and comprises an annular boss, one end of the stator winding penetrates through one exposed section in the axial direction of the motor, and one end of the stator winding surrounds one annular boss in the circumferential direction of the motor; and one annular boss is used for enclosing one annular cover plate to form an accommodating cavity, and the accommodating cavity is used for accommodating one end of the stator winding immersed by cooling liquid. According to the motor, the accommodating cavity capable of immersing the end winding can be enclosed at the end of the stator, so that 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,尤其涉及一种绕组浸没液冷的电机、动力总成及车辆。该电机包括定子铁芯、定子绕组、一个环形盖板以及一体注塑成型的注塑件;定子铁芯的多个绕组槽用于固定注塑件和定子绕组,注塑件包括多个嵌入段和一个露出段。每个嵌入段沿电机的轴向嵌入一个绕组槽,一个露出段覆盖于定子铁芯的一个轴向端面,一个露出段包括一个环形凸台,定子绕组的一端沿电机的轴向穿过一个露出段,定子绕组的一端沿电机的周向环绕一个环形凸台,一个环形凸台用于围合一个环形盖板形成一个容纳腔,容纳腔用于容纳冷却液浸没定子绕组的一端。该电机能够在定子的端部围合形成可以浸没端部绕组的容纳腔,增强对定子绕组的冷却效果,提高电机的功率。
