Abstract

In a non-contacting position sensor (,), an angular positioning of a rotating object, such as a crankshaft, is measured by a Hall effect device (,) that remains stationary in an air gap (,) between a helical flux linkage member (,) and a flux generator (,), both coupled to the rotating object via a shaft (,). The flux generator (,) has a ring magnet (,). The helical flux linkage member (,) varies in thickness from a thin region (,) to a thick region (,). There is a transition region (,) between where the helical flux linkage member is thickest and where it is thinnest. As the shaft (,) rotates, the Hall effect device (,) senses a magnetic field that varies with the thickness of the helical flux linkage member (,), thereby measuring the angular position of the rotating object coupled to the shaft (,).
