Use of Capacity-Controlled rf Energized Ionization Transducer for Balancing Rotors

Abstract

A rotor‐balancing technique is described in which conventional laboratory equipment may be used. The orbiting motion of a rotating shaft within its own fixed bearings is detected by capacitor probes. After passing through the transducer circuit, the signal is displayed on an oscilloscope. It is therefore possible to obtain the necessary balancing information at operating conditions.
