Stator punching sheet, stator core, motor, power assembly and electric vehicle

The invention relates to the technical field of motors, in particular to a stator punching sheet with a plurality of communicating holes, a stator core, a motor, a power assembly and an electric vehicle. The stator punching sheet comprises a central hole, a plurality of grooves, a plurality of first communication holes and a plurality of circulation holes, each groove is communicated with the central hole along the radial direction of the stator punching sheet, and each first communication hole, each circulation hole and each groove respectively penetrate through the stator punching sheet along the axial direction of the stator punching sheet. And along the circumferential direction of the stator punching sheet, the plurality of first communication holes are arranged at intervals, the plurality of circulation holes are arranged at intervals, and the plurality of grooves are arranged at intervals. Along the radial direction of the stator punching sheet, the distance between each first communicating hole and th
