Properties:

An item consisting of a stator and rotor inductively coupled which provides accurate linear indication of shaft rotation about a reference position in the form of a polarized voltage whose magnitude is proportional to angular displacement and phase relationship indicates direction of shaft rotation. Its windings and slots are not uniformly distributed, but instead are deliberately modified to produce a linear output which is usually limited to less than plus or minus 90 degrees of effective electrical travel. Normally it has only one energization winding and one output winding. See also resolver, electrical.
