Abstract
The invention pertains to a method of continuous compensation of unbalance present in a rotor, in particular, a grinding wheel. This is done by feeding a compensation fluid into correction chambers which are rotated with and arranged on the rotor at various angular locations. The supply of fluid is effected in successive balancing operations during rotation of the rotor and as a function of the minimum and maximum unbalance signals measured by a transducer over a certain period of time. The tolerance is determined for acceptable unbalance values. The balancing operation is terminated on the basis of the minimum and maximum which is multiplied by a multiplier determined as a function of allowable variations of the measured unbalance signal.
