Abstract
The present invention is based on imparting of oscillatory motion to a rotor and to a coaxial balanced body relative to a fixed point selected at the common axis of the rotor. To eliminate an interference of imbalance datum planes on the parameters to be measured, at one stage of measurements the fixed point is used as the crossing point of the rotor axis with one of the imbalance datum planes, whereas at the next stage the rotor is along its axis by a fixed distance to a second position. The measured parameters are used to determine imbalance parameters in two imbalance datum planes.
