The invention provides a flat wire motor, a power assembly and an electric vehicle. A stator of the motor comprises a stator iron core and a stator winding, each winding groove and a center hole of the stator iron core penetrate through the two end faces of the stator iron core in the axial direction of the stator, the center hole is used for containing a rotor, and a groove opening of each winding groove faces the center hole. Each flat wire of the stator winding comprises two leading-out ends, a plurality of straight line sections and a plurality of bridging sections, each straight line section is arranged in one winding groove, two ends of each bridging section are respectively used for connecting two straight line sections in different winding grooves, and each leading-out end is connected with one straight line section. A part of the bridging section in each flat wire is exposed out of one end face in the axial direction of the stator, and the two ends of each bridging section in the part of the bridging section are connected with the two straight line sections through the two connecting sections respectively. Along the circumferential direction of the stator iron core, the line width of each connecting section is smaller than the notch width of each winding groove, and the notch width of each winding groove is smaller than the in-groove width and the line width of each straight line section or each bridging section.

    本申请提供了一种扁线电机、动力总成及电动车辆。电机的定子包括定子铁芯和定子绕组,沿定子轴向定子铁芯的每个绕组槽和中心孔贯穿其的两个端面,中心孔用于容纳转子,每个绕组槽的槽口朝向中心孔。定子绕组的每根扁线包括两个引出端、多个直线段和多个跨接段,每个直线段分别排列于一个绕组槽中,每个跨接段的两端分别用于连接不同绕组槽中的两个直线段,每个引出端连接一个直线段。沿定子轴向每根扁线中一部分跨接段露出于一个端面,一部分跨接段中每个跨接段的两端分别通过两个连接段连接两个直线段。沿定子铁芯的周向,每个连接段的线宽小于每个绕组槽的槽口宽度,每个绕组槽的槽口宽度分别小于槽内宽度、每个直线段或每个跨接段的线宽。
