Brushless AC drive using an axial flux synchronous PM motor with low resolution position sensors

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...

Description
Summary: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.
