Abstract

A bearing with a magnetic field sensor for detecting the angular position of one element of the bearing relative to a second element of the bearing. The bearing has a ring of ferromagnetic material mounted on the rotating element. The ring has a multiple of magnetic pole segments around its circumference. The magnetic pole segments are arranged so that half of the segments are north poles and the other half of the magnetic pole segments are south poles, thus forming a two-pole ring. Two magnetic field detectors are located proximate the ring at two locations 90 degrees from one another.
