Teamwork of Simulations and Hall Sensor Measurements for the Design of Magnetic Sensor Systems

Thomas Schliesch, Thomas Lindner

Abstract

New magnetic sensor systems like stray field compensating specimen demand new challenges for the design of respective permanent magnets and sensors themselves. The collaboration of FEM simulations with 3D-Hall sensor measurements provides new insights how to build and optimize such systems. The paper shows this by the example of two stray field compensating sensors for position detection of rotating systems. The first example provides different stages of the development of a new sensor. The second one shows steps during the improvement of permanent magnets for a commercially available sensor system. Both parts also supply results about the insensitivity of those sensors against external fields up to 20mT.
