Abstract
A multi-turn measurement system includes a plurality of gears, a plurality of pinions engaging the plurality of gears, a plurality of magnets each disposed on one of the plurality of gears, and a plurality of magnetic field sensors. Rotation of the pinions about a center axis drives rotation of the plurality of gears. The magnets each have a magnetic field that changes based on an angular position of the one of the plurality of gears. The magnetic field sensors are each positioned to sense the magnetic field of one of the plurality of magnets.
