Abstract

See full text

Rotors, especially elastic rotors, are balanced by measuring unbalance values which provide information regarding the size, or rather the weight of balancing weights and the angular location where these balancing weights are to be secured to the rotor. For obtaining balancing weights an excitation force is applied to the rotor which is at a standstill or which may, but does not have to, rotate when the excitation force is applied by a hammer (11), equipped with a sensor (S) and an output (11A) to provide excitation force spectra. Further sensors (7, 8) are positioned in bearing planes (ME.sub.1, ME.sub.2) and provide response force spectra. The excitation force spectra and the response force spectra due to the rotating unbalanced rotor are then processed to obtain the unbalance compensating values required for the balancing operation.
