[0030] Embodiment 2

[0031] See also Figure 1 and Figure 2 As shown, in comparison with Example 1, as another implementation of the utility model, a noise reduction component 3 is arranged on the inner side of the body 1, and the noise reduction component 3 includes a wave washer 31 and a felt ring 32.

[0033] Working principle: First, a micro motor is moved to the working position. When in use, the first step is to connect the wiring plug 42 to an external power supply or controller. The second step is that a magnetic field is generated when current passes through the stator winding 242. The permanent magnet steel 232 in the rotor core 231 and the magnetic field generated by the stator core 241 interact with each other, thereby rotating the rotor assembly 23. The third step is that the transmission shaft 221 transmits the power generated by the rotor assembly 23 to the output shaft 211 to rotate the output shaft 211.
