Static - Dynamic and Field Balancing:

In the previous unit, you studied the simple case of unbalance and the method of removing or dropping the effect of unbalance. Majority of rotating systems are not so easy and thee balancing of such systems need two planes. The selection of the planes can be randomly done. In two plane balancing, not only the influence of the centrifugal force is removed but the moment because of this is also eliminated. The two planes needed for balancing may take care of various rotating masses. This may take care of distributed unbalance also. The balancing may be performed practically also in situ. It is known as field balancing. The field balancing will also be described in this unit.

Objectives

After learning this unit, you should be able to understand

• static and dynamic balancing,
• how two plane balancing of various rotating masses is performed, and
• field balancing.
