Application analysis of brushless motor with Hall sensor in

The smart toilets currently on the market are roughly divided into two types, one is smart toilets with cleaning, heating, sterilization, etc., and the other is smart toilets that can automatically replace films.

With the popularization of smart toilets, there will be some problems in the process of use. The smart toilet uses infrared to sense the approach and departure of the human body, and then the output signal is imported into the single-chip microcomputer, and then the brushless motor is controlled to work. Brush the motor control board to detect the speed to realize the control of the motor.

The Hall sensor is used on the brushless motor. The DC brushless motor controls the rotation of the flushing nozzle to realize the flushing of the target position. The Hall element detects the motor speed. After the detection reaches a certain number of times, the feedback signal is sent to the single-chip microcomputer. , Close the solenoid valve, stop flushing, realize the purpose of saving water, and complete the flushing work.
