  • Patent number: 4672347
    Abstract: A resolver which in a preferred embodiment utilizes a stator member, preferably made of a single piece of ferrite material, which has active stator sine poles and active stator cosine poles and a rotor member which has passive rotor poles. The active stator poles have excitation voltage inputs supplied thereto and, as the rotor poles rotate relative thereto, the sine and cosine stator poles supply voltage outputs which vary sinusoidally and co-sinusoidally, respectively, as a function of the angular position of the rotor member relative to the stator member. Multiple stator and rotor pole combinations can be used to provide resolver operation at different speeds.
