A procedure for determining the magnitude and angular position of the unbalance of a rotor is described together with an apparatus for accomplishing same. A series of impulses are generated as the rotor rotates, and these impulses relate to the periphery of the rotor. When the unbalance is determined the particular impulse number at the time of that determination is noted, and such impulse is representative of a particular point on the periphery of the rotor.
