A magnetic rotary transducer for providing a signal indicative of a rotational position of a control shaft about a rotational axis over a defined range of rotation is disclosed. The magnetic rotary transducer comprises a pair of magnets and a rotor including a pair of loop pole pieces, and an elongated pole piece having a first end adjoined to one of the loop pole pieces and a second end adjoined to the other loop pole piece. Each loop pole piece includes an inner surface defining an air gap area. The control shaft is positioned within the air gap area of one of the loop pole pieces and adjoined thereto whereby the rotor synchronously rotates with the control shaft about the axis over the defined range of rotation. The pair of magnets are adjoined to the other loop pole piece whereby two separate and distinct magnetic fields are generated within the air gap are of the loop pole piece. The magnetic rotary transducer further comprises a magnetic flux sensitive transducer positioned within the air gap area. The magnetic flux sensitive transducer is operable to provide a signal indicative of the rotational position of the control shaft.
