Abstract
A method for reducing the stable rotation speed of an automatic ball balancing system is used with an automatic ball balancing system that has a rotor that has an annular track, with at least one ball provided for rotation inside the track. First, an optimum rotation speed wthat is between the unstable critical rotation speed wof a ball and a working rotation speed w is first determined. In the next step, the rotor is accelerated to the optimum rotation speed w. Next, the acceleration of the rotor is reduced until the balls are stationary relative to the track, and then the rotor is accelerated to the working rotation speed w.
