Abstract:
An angle sensor includes a ring magnet adapted to be attached to a rotatable shaft. The ring magnet has an axis of rotation and an inner radius and an outer radius extending from the axis of rotation to define an annulus. A first magnetic sensor is situated proximate the ring magnet to measure magnetic field lines within the annulus, and a second magnetic sensor is situated proximate the ring magnet to measure magnetic field lines outside the annulus.
