I am currently working with torque control of a BLDC motor. Hall effect
sensors are used to determine the position of rotor(permanent magnet).
The stator is energized by 3-phase current.
Depending upon the signals recieved from the hall effeect
sensors,particular stator coils are energized (commutation ). I am not
clear why the position of rotor needs to be determined to keep the
motor running.
Need some help.
