The hall sensor is used for commutating the motor. Commutation is the process for defining how current flows in each motor phase pair. Many controllers have an “Auto Configuration” option that figures out the winding sequence compared to the hall sequence. We also provide a winding phase diagram on our interface -095 drawings. Hall leads and Hall pairing are called out on the -095 drawing. “Pairing” is the definition of how the hall sensors are paired with the motor phases. For instance, Phase AB might be paired with Hall 1, Phase BC with Hall 2 and Phase CA with Hall 3.
