easily broken
The Hall of the motor is easy to be damaged because the antistatic ability of the Hall sensor chip of the motor is poor. The brushless motor detects the signal of the real-time running position of the winding through Hall, and then processes the collected signal through the microprocessor or special chip, and controls the corresponding drive circuit in real time to control the motor winding.
The popular motor Hall sensor chips produced in the CMOS process have poor anti-static ability, and if there is no special anti-static equipment on the motor production line, Hall sensors are vulnerable to electrostatic damage, usually this damage cannot be detected when the Hall sensor is still able to work, but the life has been greatly reduced, especially in high temperature or humid environments.
Generally speaking, as long as the phone is not often dropped. Do not connect directly to the computer. The Hall sensor is not easy to break, it is installed inside the mobile phone, used to sense the operating signal received by the mobile phone, not easy to break
