A torque motor actuator includes a first magnetic pole piece, a second magnetic pole piece, an armature, and an armature stop. The second magnetic pole piece is spaced apart from the first magnetic pole piece to define an armature gap. The armature is disposed in the armature gap and is spaced apart from the first and second magnetic pole pieces. The armature includes a magnetically permeable material and has a central portion, a first arm, and a second arm. The armature is rotationally mounted at the central portion, and the first and second arms extend, in opposite directions, from the central portion. The armature stop extends from the first arm, and comprises a non-magnetic material. The armature stop is configured, upon rotation of the armature, to selectively engage one of the first or second magnetic pole pieces to thereby limit armature rotation.
