TABLE OF CONTENTS When driving, or riding, in a car you want forward motion. That is the reason for being in the vehicle. You don't want noise, vibration, rattles, squeaks groans or screams. When operating machinery we usually want the rotational motion but not the side effects.
Scream now.
It is all a matter of tolerances, tooling, unbalance correction methods and locations, balancing machines, and many other details that affect the performance of a product.
Balancing may also be required due to the rotor design, or lack of design. Design errors, wide manufacturing tolerances, assembly procedures and rotor function, may cause large amounts of unbalance.
Generally, the addition of a balancing operation allows for opening up manufacturing tolerances. Sometimes this is carried too far and the result is a higher amount of unbalance than what can be efficiently or even practically removed.
The 'value added' by balancing comes from broadening of manufacturing tolerances and material specifications, elimination of warranty failures, increased product performance, and the customer's perception of a 'quality' product.
Up to now, we have been looking at the results of not balancing to optimum levels. Now we turn to the process of balancing.
Rotor balancing involves all three of the above parameters.
