Differential Hall-effect sensors aid rotational speed control News & Analysis 11/27/2002 Post a comment The rotational speed of motors with gear teeth can be precisely monitored and controlled with new-generation Hall-effect sensors. BiCMOS technology provides devices with high-sensitivity and speed, and yet small enough to fit inside motor housings or other tight spaces. Allegro's ace applications engineer explains their principles of operation, and provides a guideline for analog signal conditioning.
