[0027] like Figures 1 to 9As shown, a magnetic levitation motor stator assembly capable of rapid assembly includes a first fixed plate 1, a first magnetic yoke 2, a coil 3, a second magnetic yoke 4 and a second fixed plate 5, wherein the first fixed plate 1 and the second magnetic yoke 4 are annular structures and are coaxially arranged, the upper and lower ends of the first magnetic yoke 2 are respectively inserted into the first positioning groove 14 of the first fixed plate 14 and the second positioning groove 41 of the second magnetic yoke 4, the coil 3 is wound on the first magnetic yoke 2, the number of the first magnetic yokes 2 is multiple, and they are evenly distributed circumferentially about the second magnetic yoke 4, the second fixed plate 5 is arranged on the side of the second magnetic yoke 4 away from the first fixed plate 1, and a second clip 51 is fixedly arranged on the second fixed plate 5, and the second clip 51 is inserted into the second magnetic yoke 4 and then clipped into the second clip groove 23 on the side of the first magnetic yoke 2.

[0028] like Figure 4 and Figure 5 As shown, the first fixed plate 1 includes a plate body 11, and a positioning vertical plate 12 is fixedly connected to the plate body 11 along the radial direction. The positioning vertical plate 12 is U-shaped, and a first positioning groove 14 is formed in the opening area of ​​the positioning vertical plate 12. Adjacent positioning vertical plates 12 are fixedly connected by connecting vertical plates 13, thereby forming a continuous annular structure to increase structural strength.

[0029] like Figure 3 and Figure 5 As shown, a first clip 15 protruding outward is provided in the horizontal direction on the inner side of the positioning vertical plate 12, and a first slot 22 is provided on the side of the first magnetic yoke 2.
