Abstract
An armature locating and holding structure in which the armature only partially overlaps one of the magnetic poles so as to produce a magnetic tensile force on the armature tending to pull the armature toward the partially overlapped pole and a magnetic gap tending to apply a rotational balance force so as to pull the armature structure toward a pair of stops that limit movement of the armature toward the partially overlapped pole and also limits the rotation of the armature by reason of the magnetic gap.
