Why Hall sensor is used in BLDC motor?
“Hall effect sensors are solid-state, magnetic field sensors. They work on the principle that when a conductor with current flowing through it is placed in a magnetic field, the magnetic field induces a transverse (or sideways) force on the charge carriers, which pushes them to the sides of the conductor—negative to one side and positive to the other side. This buildup of charge on the sides of the conductor induces a voltage. This effect is referred to as the Hall effect, after its discoverer, Edwin Hall. “
