you cant get precise positioning from hall sensors alone, thats what the encoder is for. By adding hall sensors you just simplify determining the commutation of the motor. The benefit to adding hall sensors is that you can start the motor from a dead stop and automatically be in the right commutation phase.

thanks for info ,but i think hall sensor we can not do positionting as encoder correct me if i am wrong
