Claim:
1. A torque motor actuator, comprising: a first magnetic pole piece; a second magnetic pole piece spaced apart from the first magnetic pole piece to define an armature gap; an armature disposed in the armature gap and spaced apart from the first and second magnetic pole pieces, the armature comprising a magnetically permeable material and including a central portion, a first arm, and a second arm, the armature rotationally mounted at the central portion to rotate about a rotational axis, the first and second arms extending, in opposite directions, from the central portion and perpendicular to the rotational axis; and an armature stop extending from the first arm, the armature stop comprising a non-magnetic material and configured, upon rotation of the armature, to selectively engage one of the first or second magnetic pole pieces to thereby limit armature rotation, wherein:
