3. Position, speed or torque control of a brushless DC rotary motor with digital Hall sensors
and an incremental quadrature encoder on its shaft. The brushless motor is controlled
using Hall sensors for commutation. It works with rectangular currents and trapezoidal BEMF
voltages. Scaling factors take into account the transmission ratio between motor and load
(rotary or linear). Therefore, the motion commands (for position, speed and acceleration)
expressed in SI units (or derivatives) refer to the load
in IU units, refer to the motor.
