The decision has to be made about how to mount the rotor in the balancing machine. One solution is to fabricate a mandrel to balance the fan blade between the machine pedestals. The other alternative is to mount the fan blade on the end of the shaft in an overhung configuration, with the fan blade outboard of both balancing machine pedestals.

normal industry standards for impeller balancing are typically single-plane balanced if the ratio of diameter to width D/b is 6.0 or greater. The width b is measured between the outside of the shrouds at the impeller OD. For and open impeller it is in essence the vane height at the OD. Two-plane (or dynamic) balancing is typically performed ...

The term ''Balance'' can be defined as an ideal condition of a Fan that has neither static nor dynamic ''Unbalance''. Such a fan does not impart any vibratory force or motion to its Bearings as a result of centrifugal forces. Balancing. Balancing is a procedure by which the mass distribution of a fan is checked and, if necessary, adjusted.
