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.
