[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6As shown, the utility model can be implemented through the following embodiments: a speed regulating motor includes a motor body 1, the motor body 1 is installed with a rear cover 3 by bolts 2, an installation chamber 31 is arranged in the rear cover 3, an installation plate 311 is arranged on the inner wall of the installation chamber 31, a Hall electric control board 4 is installed on the installation plate 311, a Hall element 41 and other electric control elements 42 are installed on the Hall electric control board 4, a fixing plate 43 is arranged on the back of the Hall electric control board 4, a slider 431 is arranged on the fixing plate 43, and a slide groove 3111 of corresponding shape is arranged on the installation plate 311.

[0023] By opening an installation chamber 31 in the rear cover 3, a mounting plate 311 for mounting the Hall electric control board 4 is provided in the installation chamber 31, a slide groove 3111 is provided in the installation plate 311, the back of the Hall electric control board 4 is a fixed plate 43, and a slider 431 is provided on the fixed plate 43, so that the installation plate 311 is slidably connected with the Hall electric control board 4, which is convenient for installation and disassembly.

[0024] like Figure 2 and Figure 4 As shown, a mounting groove 32 is provided on the inner wall of the mounting chamber 31, and the mounting groove 32 is located above the mounting plate 311. The opening of the mounting groove 32 facilitates the Hall electric control board 4 installed on the mounting plate 311 to make room for installation.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a mounting portion 5 is provided on the outer wall of the rear cover 3, and a mounting groove 32 penetrates the mounting portion 5. The mounting groove 32 penetrates the mounting portion 5, so that the Hall electric control board 4 can be inserted into the mounting portion 5, thereby facilitating fixing the Hall electric control board 4 on the outer side of the rear cover 3.

[0026] like Figure 1 As shown, screw holes 51 are provided on both sides of the mounting portion 5, and screw rods 6 are installed on the screw holes 51.
