Development of an Angular Measurement System by Linear Hall Sensors on Stepping Motors

An non-contact type application on the permanent magnet and linear Hall-effect sensors gauging rotary system is introduced in this paper. For such a contactless system, there will be low wear exhaust. This leads to a longer life span in association, and in particular, high reliability to achieve continuous use. The main component of the angular gauge depends on the Hall voltage under the rotation of the magnetic induction. This kind of system is low-cost and holds reliable operation in special environmental conditions, such as high vibration, humidity, or dust. Higher accuracy and precision can be achieved as shown in the experimental results. Keywords--sensors, gauging, rotary, vibration, humidity, dust.
