Abstract
A resolver (20, 21) is provided with redundant excitation windings in which only a single excitation winding (E1) is energized externally. Cross coupling from the externally energized winding (E1) excites the other excitation winding (E2). A control circuit (27, 28) monitors the excitation of the redundant excitation winding (E2) and switches the excitation to the redundant excitation winding (E2) in the event of a failure of the externally winding (E1).
