Abstract
An apparatus for measurement of absolute position of a movable machine member is provided. The machine member is moved by a motor and reduction device producing rotation of the machine member in proportion to relative rotation of the motor rotor and motor stator. Two angular position measuring devices provide output signals representing relative positions related to the machine member position and differentiated one from another.
