HALL SENSOR LOCATION The Fig 2 is the hall sensor location, where marks the IC number. The best sensitivity, which can be intensified as much as possible, depends on the vertical distance and position between magnetic pole and the hall sensor (Fig 3). For the single-phase motor, this design is very important.
