ENGINE GOVERNOR EDDY-CURRENT DAMPER MECHANISM AND METHOD ABSTRACT OF THE DISCLOSURE A method of damping governor over compensation and searching in an engine/generator set comprises the provision of an eddy current damper in association with a governor member of the system. The preferred eddy current damper comprises a governor arm having an eddy current plate on one end thereof, the plate being oriented to move through a magnetic field generated by an industrial magnet mounted on the engine/generator set. As the governor arm moves in response to changes in engine speed the eddy current plate is passed through the magnetic field, the generated eddy current causing resistance to motion and a damping effect. Through a conventional linkage mechanism, the damping effect is translated to control of the engine throttle. As a result, over-compensation is generally reduced and/or searching is inhibited.
