Entwicklung mehrdimensionaler magnetfeldbasierter Positionsmesssysteme am Beispiel eines inversen Pendels

Exact determination of displacement and rotation of moving parts is a frequent task in automotive and industrial automation. Systems consisting of permanent magnets and magnetic flux sensors provide the advantage of a precise, robust, non-contact, i.e. wear-free measurement method. Magnetic sensors based on HallinOne® technology enable the design of systems which make use of the entire (3D) set of relative translational and rotational position coordinates for the determination of the required position. However, the design of corresponding multi-axis magnetic encoder applications poses a quite complex task for the engineer. In this contribution, we explain the design process for multi-axis magnetic position sensing systems and present an inverse pendulum solution as an example
