Abstract
A vane-type galvanometer employs a stator having a unibody type structure. Narrow bridge regions of the stator are magnetically saturated to produce regions of high magnetic reluctance and salient magnetic poles in the stator. A pre-wound bobbin is mounted to the stator for generating a control flux to thereby exert a torque on a vane armature.
