ABSTRACT:
A variable reluctance position sensor and a method for determining a position of a rotating body are provided. The variable reluctance position sensor includes a rotatable member configured to be operably coupled to the rotating body. The rotatable member has a first non-magnetic body portion and a plurality of magnets disposed equidistant from one another around an exterior region of the first non-magnetic body portion. The variable reluctance position sensor further includes a stator assembly having a second non-magnetic body portion with an aperture extending therethrough for receiving the rotatable member therein. The stator assembly further includes a plurality of coils and a plurality of coil brackets. Each coil of the plurality of coils is attached to a respective coil bracket of the plurality of coil brackets. The plurality of coil brackets are fixedly attached equidistant from one another to the second non-magnetic body portion. Rotation of the rotatable member induces the plurality of coils to generate voltage signals indicative of a position of the rotatable member.
