摘要： An active balancing system for rotating machinery is provided which is light weight, solid state and powered by radiant energy. One or more balance rings coupled to the rotating machinery each have balancing elements which are moved to a selected position by actuators whose operation is controlled according to measured vibration resulting from imbalance of the machinery. The actuators are powered by an electrical energy generating device, such as a photo cell or a photovoltaic element, which is coupled to the machinery and located across an air gap from a source of radiant energy such as an array of light emitting diodes.
