The invention relates to the technical field of motors, in particular to a stator silicon steel sheet with a radial flow channel, a stator core, a motor, a power assembly and an electric vehicle. The stator silicon steel sheet with the radial flow channel comprises a plurality of first cooling holes, a plurality of second cooling holes and at least one radial flow channel. Along the axial direction of the stator silicon steel sheet, each first cooling hole and each second cooling hole penetrate through the stator silicon steel sheet. And along the circumferential direction of the stator silicon steel sheet, the plurality of first cooling holes are arranged at intervals, and the plurality of second cooling holes are arranged at intervals. Along the radial direction of the stator silicon steel sheet, the distance between each first cooling hole and the center of the stator silicon steel sheet is larger than that between each second cooling hole and the center of the stator silicon steel sheet, and the second cooling holes are closer to the center of the stator silicon steel sheet than the first cooling holes. Each radial flow channel is used for communicating with one first cooling hole and one second cooling hole, and the first cooling holes and the second cooling holes are adjacently arranged in the radial direction of the stator silicon steel sheet. The radial flow channels can improve the heat dissipation performance of the motor.

    本申请涉及电机技术领域,尤其涉及到一种带径向流道的定子硅钢片、定子铁芯、电机、动力总成及电动汽车。该带径向流道的定子硅钢片包括多个第一冷却孔、多个第二冷却孔和至少一个径向流道。沿定子硅钢片的轴向,每个第一冷却孔、每个第二冷却孔贯穿定子硅钢片。沿定子硅钢片的周向,多个第一冷却孔间隔排列,多个第二冷却孔间隔排列。沿定子硅钢片的径向,每个第一冷却孔与定子硅钢片中心的距离大于每个第二冷却孔与定子硅钢片中心的距离,第二冷却孔比第一冷却孔更靠近定子硅钢片的中心。每个径向流道用于连通一个第一冷却孔和一个第二冷却孔,第一冷却孔和第二冷却孔沿定子硅钢片的径向相邻排列。径向流道可以提升电机的散热性能。
