ABSTRACT:
A device for indexing a rotor (17) of a machine (13) to be balanced utilizes the output signal (A) from a generator (15) connected to the machine rotor (17). The generator (15) produces a continuous sinusoidal output signal (A) proportional to the position and speed of the associated rotor (17). Detector means (37) detect a predetermined output from the generator (15) so that an indicator (41) issues an indication each time the detector means (37) detects the predetermined output. Thus, an operator can physically index the angular position of the rotor (17) with respect to the predetermined output (A) from the generator (15) when an indication is provided so that the position of the rotor (17) is referenced to the output signal (A) of the generator (15).
