ABSTRACT:
A rotary variable differential transformer is provided having a substantially linear output over .+-.35.degree. of rotation of the rotor. Two secondary windings in series opposition extend over adjacent nominal quadrants of the stator. A primary winding extends about substantially half the stator. The rotor includes two diametrically opposed pole pieces each defining arcuate segments. One segment is approximately one half the arcuate length spanned by the secondaries and the other segment one third the arcuate length of the remainder of the stator.
