The is a semiconductor sensor. Under the action of the force, the electron flow shifts to one side when passing through the semiconductor, causing the side of the chip to generate a potential difference, which is the so-called voltage.
The voltage changes with the intensity of the magnetic field. The stronger the magnetic field, the higher the voltage, the weaker the magnetic field, and the lower the voltage. The voltage value is very small, usually only a few millivolts, but it is amplified by the amplifier in the integrated circuit. That is, the voltage is amplified enough to output a stronger signal.
In the motor, a rotating magnet acts as a switch to control the magnetic flux. When the magnet is close to the IC, the voltage is high (on), the magnetic field deviates from the integrated chip, and the voltage is eliminated (off). In this way, the change of the output voltage of the IC can indicate that the shaft is at a certain position. Using this working principle, the motor can be controlled to rotate.
