DESCRIPTION OF RELATED ART
[0002] Typically, the circuit board of motors for mounting a Hall element is often directly installed on the terminal insulator of the stator assembly, and the Hall element protrudes out of the circuit board and leans against the outer end of the rotor assembly to detect position signals of the rotor. However, the installation structure of the Hall element is often unreliable, and the circuit board and the Hall element are easily detached from the terminal insulator when the motor is running or when vibration happens.
Meanwhile, because the circuit board and the Hall element are exposed, they tend to be stained or contaminated, which adversely affects the operation of the motor, and requires high maintenance costs, and decreases the market competitiveness of products_ SUMMARY OF THE INVENTION
