Abstract :
In this paper a new control scheme for AC brushless drives in which Hall effect sensors are used as rotor position sensors is presented. The proposed control algorithm´s most innovative feature is its adaptability to the whole speed range, including start up. A study on the drive´s torque ripple has also been carried out and a way to minimize it in all operating conditions has been developed. Finally the algorithm has been implemented and tested in order to drive an axial-flux PM machine for home applications.
