Advanced field balancing technique: How to locate the heavy spot before the trial weight is added?

"Where should I put the trial weight?". This may be a challenging question when the initial unbalance is severe. We made a demonstration video showing how to locate the heavy spot by measuring the 1X trace during the coast-down procedure.

The principle for this technique is simple: The angular position of the heavy spot is in phase with the "absolute vibration phase" of the 1X vibration at low speed zone.

By knowing where the heavy spot is before adding the trial weight, you can have the following benefits:

1. Work safely
2. Prevent damaging the machine
3. Get more accurate balancing factors which are derived in the linear zone (smaller vibration level).
4. Save your time and do the balancing quickly.
5. In case your machine rotates at a resonance zone and has a very unstable phase, usually it is hard to conduct balancing. The technique of heavy spot estimation is helpful to find out the correct balancing spot for such cases.
