The XYO technology reduces vibration by compensating for variable mass imbalance during the operation of industrial fans. Tests show that the a prototype XYO balancer had a significant impact on reducing vibration levels of these fans. Some of the benefits of using XYO include:
Vibration Decreased by 80%
The primary cause of engine cooling fan vibration is mass imbalance due to manufacturing tolerances. Factory balancing is usually done after the fans come off the production line. This process is expensive, time consuming and does not account for balancing that may be required once the fan is in use. During normal operation, erosion and debris build-up can also contribute to the mass imbalance, leading to violent vibration.
The objective of the test was to determine the impact that an XYO system would have on the vibration of engine cooling fans (Figure 2).
Vibrations were measured with two velocity probes on the shroud (Figure 3).
The prototype XYO balancer was designed with a compensating capacity of 180g.mm; however, the XYO balancer capacity can be designed for larger imbalances if desired. The XYO balancer was installed inside the hub of the impeller, as shown in Figure 4.
Four different mass imbalances were tested with and without the XYO balancer installed on the engine fan:
A small screw and several nuts were used as imbalanced masses and were positioned on the impeller as illustrated in Figure 5. The fan was allowed to run at an operating speed of 2000 RPM.
Figure 6 shows the results of different mass imbalances tested on an engine fan with an XYO balancer and an engine fan without an XYO balancer. The capacity of the XYO balancer tested in this study was 180g.mm, so when the 265g.mm mass imbalance was tested, the vibration measured with an XYO balancer increased slightly. Table 1 summarizes the results.

The XYO technology was successfully applied to engine cooling fans. Vibration was significantly (80%) reduced using a prototype XYO balancer. Engine fan manufacturers can benefit with XYO in the following areas:
