MAGNETIC ENCODER FOR PRODUCING AN INDEX SIGNAL
Abstract:
A magnetic encoder has a high resolution track including a plurality of North/South pole pairs defining a plurality of pole junctions, and a reference track including a North/South pole pair defining a North/South pole junction aligned with a first pole junction of the high resolution track, and a South/North pole junction aligned with a second pole junction of the high resolution track. Only a single pole junction of the high resolution track is positioned between the first and second pole junctions of the high resolution track.
