Abstract
The utility model discloses a motor shaft used on a vehicle. The motor shaft comprises a rotating shaft body, wherein the rotating shaft body comprises a threaded section, a smooth shaft, a middle section and a tail section which are sequentially arranged; the diameter of the threaded section is less than that of the smooth shaft; a tool withdrawal groove is formed between the threaded section and the smooth shaft; an annular groove is formed between the smooth shaft and the middle section; and ribs are arranged in the peripheral direction of the outer surfaces of the middle section and the tail section at intervals. The motor shaft is reasonable in structural design, a rotor can be precisely buckled due to the fact that the ribs consisting of grooves and convex ridges are arranged on the middle section and the tail section, the service life of a motor is prolonged, and the motor shaft is practical.
