Hall effect sensor is generally used in sensing applications like current sensing and speed sensing. The control circuit connected with the hall sensors are in fact "blind" and respond entirely to the hall sensor signals in order to produce the required feed backs to the electromagnet coils. Some motors have a 9th wire - the speed sensor. Alternative Digital Hall-effect Sensors: A3141, A3142, A3143, US1881, OH090U. Hall Sensors are a low cost yet reliable type of commutation feedback Used for commutation because they provide absolute but rudimentary position within 1 electrical cycle Allows systems to move the motor immediately on start-up rather than wait for a "wake-and-shake" routine. During the one electrical cycle, the motor has six trigger signals. A Hall Effect Sensor is a widely used sensor that provides rotor position feedback to a motor controller. The classical way of controlling the position of a DC brushless motor is using a position feedback device of a decent resolution to allow sinusoidal commutation of the motor (incremental encoder, resolver, linear hall sensors, etc). It is the hall sensors that tell the controller what is the current position of the motor. The control circuit connected with the hall sensors are in fact "blind" and respond entirely to the hall sensor signals in order to produce the required feed backs to the electromagnet coils. In some ways, Hall effect sensors can ultimately perform a similar function as a reed switch, but with no moving parts.
