description The invention discloses a permanent magnet synchronous motor rotor punching sheet structure for an electric motorcycle, which comprises a punching sheet body, the punching sheet body is divided into a plurality of fan-shaped areas with the same shape and size, groove groups are arranged in the fan-shaped areas close to arc edges, and each groove group comprises an inner-layer groove body and an outer-layer groove body which are respectively used for installing magnetic steel. The outer groove body is arranged on one side, close to the arc edge of the fan-shaped area, of the inner groove body; the inner-layer groove body comprises an inner-layer middle groove and inner-layer side grooves formed in the two sides of the inner-layer middle groove, the inner-layer middle groove and the inner-layer side grooves are rectangular, the inner-layer middle groove is symmetrically formed in the center line of the fan-shaped area, and the two inner-layer side grooves are symmetrically formed in the two sides of the inner-l
