The invention relates to the technical field of motors, and provides a stator punching sheet with a circumferential flow channel, a motor, a power assembly and an electric vehicle. The stator punching sheet comprises a plurality of communicating holes and a plurality of circumferential flow channels. Along the axial direction of the stator, each communication hole and each circumferential flow channel penetrate through the stator punching sheet. Along the circumferential direction of the stator, the plurality of communicating holes are arranged at intervals, the plurality of circumferential flow channels are arranged at intervals, and each circumferential flow channel is communicated with at least two communicating holes; along the radial direction of the stator, the distance between the center of the circumferential flow channel and the center of the stator punching sheet is greater than the distance between the center of the communication hole and the center of the stator punching sheet. The cooling working medium can flow in the circumferential direction of the motor after entering the motor, and the heat dissipation effect of the motor is optimized.

    本申请涉及电机技术领域,提供一种具有周向流道的定子冲片、电机、动力总成及电动汽车。该定子冲片包括多个连通孔和多个周向流道;沿定子的轴向,每个连通孔、每个周向流道贯穿定子冲片;沿定子的周向,多个连通孔间隔排列,多个周向流道间隔排列,每个周向流道与至少两个连通孔连通;沿定子的径向,周向流道的中心与定子冲片中心的距离大于连通孔的中心与定子冲片中心的距离。冷却工质进入电机后能够沿电机的周向流动,优化电机的散热效果。
