Abstract

A non-contact angle/torque sensor comprises an upper rotor in an annular shape having a central axis, and in which magnets are located, the magnets positioned within the annular shape around the central axis with the north and the south poles of adjacent magnets being oriented opposite to one another, and a lower rotor in an annular shape and sharing the central axis of the upper rotor, and located spaced outwardly from an outer circumferential surface of the upper rotor. The lower rotor has upper and lower stators spaced apart along the central axis. The upper stator has upper and lower backplanes and a series of upper and lower extensions extending from the respective backplanes. The upper extensions and the lower extensions are not intermeshed or overlapped.
