What is Hall Motor?
Hall is a semiconductor sensor, under the effect of lorentz force, the
electron flow is deflected to one side when passing through hall
semiconductor, causing the film to generate potential difference from
the side. This is called hall voltage.
The hall voltage varies 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 hall voltage value is very
small, usually only a few millivolts. However, amplification by an
amplifier in an integrated circuit enables the voltage to be amplified
enough to output a stronger signal.
In the motor, a rotating magnetic steel is used as the switch to
control magnetic flux. When the magnetic steel is closer to hall
integrated circuit, hall voltage is large, and the magnetic field
deviates from the integrated chip, hall voltage disappears.In this way,
the output voltage change of hall integrated circuit can indicate that
the shaft is in a certain position, which can be used to control the
motor rotation.
