Design and Implementation of a Computerized Balancing System


In this work, a new computerized measurement system for multi-plane flexible rotorbalancing has been designed and implemented. This system can be used to modernize andenhance conventional low-speed balancing machines or for field balancing applications. Thissystem adds very important features to balancing machines such as multi-plane flexible rotorbalancing, high accuracy, stability, and high dynamic range. Also, the proposed flexible rotorbalancing technique permits accurate balancing of high-speed rotors utilizing low-speedbalancing machines or field balancing at speeds lower than the critical speeds. The proposeddigital Wattmetric technique in conjugation with advanced measurement circuitry have led tosignificant improvement in balancing accuracy even when the unbalance signal is buried intohigh level of noise
