Condition Monitoring of Rotating Electrical Machines — Recommend this title to your library

## Thank you

This book has described the following major monitoring techniques for electrical machines, in the following ascending order of usefulness: Shaft voltage or current has been suggested as universal panaceas for comprehensive electrical machine monitoring but have not been proven as reliable CM techniques. Shaft flux, current and power signals are capable of detecting faults in both the electrical and mechanical parts of a drive train. Shaft flux monitoring is non-invasive, broad bandwidth (5 Hz-20 kHz) and uses a single flux coil sensor, but it is complex to analyse and untested in the field. Little further work has been done on this technology since its inception in the 1980s, therefore it cannot be recommended to operators. However, some new industrial applications, such as traction, electric cars or aerospace, could make it exceptionally appealing because of its ease of fitting and universality. Motor speed has been analysed to detect rotor electrical faults, IAS, it is simple and requires a low bandwidth signal (<1 kHz) but has not been widely used by operators. Vibration and shock pulse monitoring and analysis are non-invasive but use widely available sensors and broad bandwidth with complex analysis (5 Hz-50 kHz). The precise selection and location of these sensors is very important as they are generally distant from the seat of any defect action and signals maybe attenuated by machine and bearing enclosure responses.
