The brushless motor is required to be extremely sensitive, with low speed and large torque, and extremely small volume. Therefore, there are scenarios that cannot be achieved by traditional electronic speed controllers driving brushless motors.

[0030] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A brushless motor with a Hall sensor includes a housing 1.

[0031] Among them, refer to Figure 3 and Figure 4 In a preferred implementation manner, a sleeve is fixedly connected above the base 5. By providing the sleeve 5, a mounting space can be provided for the bearing 6;

[0032] Among them, refer to Figure 3 and Figure 4 In a preferred implementation manner, a slot is opened at one end of the Hall plate 4, and the size of the slot is adapted to the size of the sleeve. By providing the Hall plate 4, the speed and large torque of the brushless motor can be reduced.

[0033] Furthermore, refer to Figure 3 and Figure 4, in a preferred embodiment, a guiding block is installed at one end of the Hall plate 4. The guiding block is arranged on the outer surface of the stator 3. By providing the guiding block, the stator 3 can rotate smoothly inside the housing 1.

[0034] Among them, referring to Figure 3 and Figure 4 , in a preferred embodiment, one end of the bearing 6 is rotatably connected inside the sleeve. By providing the sleeve, the stator 3 can rotate in a guided manner inside the housing 1.

[0035] Furthermore, referring to Figure 3 and Figure 4 , in a preferred embodiment, a fitting block is installed at the bottom end of the Hall plate 4.
