Abstract
A method of balancing a mirror in a limited rotation motor system is disclosed. The method includes the steps of providing a mirror on a rotor shaft of the limited rotation motor system such that the mirror is initially imbalanced in that the mirror is slightly more weighted to lean to a front side of the mirror that includes a front reflective face of the mirror, and adjusting at least one threaded counterweight screw on a back side of the mirror at least to a position at which the mirror becomes balanced between the front and back sides.
