Abstract
A color wheel is provided with a balancing device. The balancing device encompasses an essentially circular track whose center point coincides with the axial center of rotation of the color wheel. The track is provided with at least two mutually independent, movable balancing weights. Moving the balancing weights along the track requires a force greater than the gravitational force of the balancing weight. To balance a color wheel, a determination is made of a position in which a balancing weight corresponding to the total weight of the balancing weight system would have to be placed in order to balance the color wheel. At least one of the balancing weights is then moved to the position, according to the determination, where one of the balancing weights corresponding to the total weight of the balancing weight system would have to be placed.
