Does different balancing speed indicate different unbalance values?

Unbalance is a vector and a physical quantity related to the geometry of the component being balanced. It remains the same at all speeds as long as the component does not deform and remains rigid. In, good hard bearing dynamic balancing machines, the unbalance value and the angle will remain the same within permitted variations when checked at different balancing speeds. Since, the electronics operates at low voltages (say +/- 15 V), older machines have switches and markers to take care of variations in the results. A variation within +/- 5 % of the values indicated in different speed ranges is acceptable, and the machine can be classified as a very good machine.
