Bearing Health Diagnosed with a Mobile Phone: Acoustic Signal Measurements Can Be Used to Test for Structural Faults in Motors

According to industry statistics, bearings are the components of low-voltage motors that fail most often. At the same time, the diagnostics of rollingelement bearings constitute a well-established component of the rotating machinery condition-monitoring domain. In many cases, however, the cost of installing a high-end, accelerometer-based bearing condition-monitoring system, which is the most comm...
