A transducer of motion includes an in-line toothed armature, this is placed near two cores with coils displaced one with respect to another by even quarters of pitch of transducer thread. A scale with magnetic marks of alternating polarity is used as an in-line toothed armature, and two magneto-modulation heads are used as two cores with coils, those are placed symmetrically at both sides of the scale. Excitation windings of the magneto-modulation head are connected to excitation sinusoidal current generator, and the first and second, third signal windings are connected to each other in differential circuit. |
