Bldc with hall sensor
Web2 Three Hall Sensor Mode In a three Hall system, Hall sensors are placed 120° apart and are aligned to three phases so each Hall sensor will correspond to one of the 3-phases. The DRV10970 supports two different ways in which a Hall sensor can be placed, that is, 0° Hall placement and 30° Hall placement. The DRV10970 also supports WebBipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three …
