Abstract :
Position sensing is needed in a large variety of applications, where more specifically Hall-effect position sensors, due to their simplicity and versatility, are elegant solutions. This paper describes a reverse engineering approach to investigate the mismatch in measured Hall-effect voltage of a dipole permanent magnet ring. Using several magnetization patterns, the position signal is reproduced, and it is concluded that by substitution of these patterns, the measured voltage can be recreated
