Rotor punching sheet shaft connecting structure

The utility model relates to a rotor punching sheet shaft connecting structure which mainly includes a rotor punching sheet and a rotary shaft. An inner hole of the rotor punching sheet is zigzag. The rotary shaft is a smooth shaft. The axial face of the rotary shaft contacting with the rotor punching sheet is in a smooth structure. For the rotor punching sheet connecting structure, the inner hole of the rotor punching sheet is zigzag, and the axial face of the rotary shaft is smooth, so under the condition that the zigzag inner hole cooperates with the smooth axial face of the rotary shaft, the production of the zigzag inner hole of the rotor punching sheet is simple, and the smooth shaft production is also simple, and consequently the production cost and the manpower and material recourses required by production are effectively reduced.
