Abstract

Die Erfindung betrifft einen Drehgeber auf magnetischer Basis, der eine erste Scheiben- oder ringartige Struktur und eine zweite Scheiben- oder ringartige Struktur umfasst, welche entlang einer Achse ausgerichtet sind, sich radial zu dieser entlang oder parallel zu einer gemeinsamen Ebene erstrecken, von einander beabstandet und relativ zueinander drehbar angeordnet sind, wobei die erste Struktur zur Erzeugung eines Magnetfeldes wenigstens zwei Magnetpole umfasst, die senkrecht zur Achse ausgerichtet sind und wobei die zweite Struktur aus wenigstens zwei in einer gemeinsamen Ebene senkrecht zur Achse angeordneten Segmenten aus einem ferromagnetischen Material zur Magnetfeldführung und -konzentration eines durch die erste Struktur erzeugten Magnetfeldes aufgebaut ist, und wobei diese Segmente wenigstens zwei Materialfreiräume derart definieren, dass die dort verlaufenden lokalen Magnetfelder zueinander nicht in Phase sind und wobei in oder nahe wenigstens dieser beiden Materialfreiräume jeweils ein magnetfeldempfindlicher Sensor zur Messung des lokalen Magnetfeldes angeordnet ist.
