ABB’s Innovation: Advanced Detection of Air Gap Eccentricity

ABB's new patent addresses this challenge by introducing an innovative method of detecting air gap eccentricity using multiple magnetic sensors. By measuring the external leakage flux in the machine and analyzing the data through advanced processing algorithms, ABB's system can accurately determine the extent of eccentricity, even detecting the smallest variations. This method greatly enhances the sensitivity and precision of fault detection, allowing for real-time monitoring of rotating machines.

How the New Detection System Works

The core of ABB's air gap eccentricity detection system relies on the use of multiple magnetic sensors strategically placed around the rotating machine. These sensors measure the external leakage flux, which is an indicator of any misalignment in the machine's air gap. The data from each sensor is processed by a central processor, which calculates the moving average of the measurements to identify the overall eccentricity. This method ensures that even the slightest deviations in the air gap are detected early, enabling proactive maintenance and reducing the risk of unexpected failures.

By integrating this detection system into existing rotating machines, manufacturers can gain a clearer picture of their equipment’s condition and detect issues before they escalate. This innovative approach provides manufacturers with a much more reliable and efficient method for monitoring machine health, resulting in fewer unplanned outages and improved operational efficiency.
