Abstract

See full text

A galvanometer unit comprises a limited-rotation motor with a load element such as a mirror attached to a shaft extending from the motor. In a servo loop that controls the angular position of the mirror, a position-sensor attached to the shaft provides position feedback information. The sensor includes a rotor which is positioned at the null point of the fundamental torsional resonance mode of the rotating system, thereby essentially eliminating feedback components resulting from the resonance.
