Diagnosis of continuous rotor–stator rubbing in large scale turbine units using acoustic emissions
Continuous rubbing between the shaft and surrounding seals or end-glands of electricity generating turbine units can escalate into very severe vibration and costly rotor damage. Therefore such rotor–stator contacts require early diagnosis so as to minimize the financial consequences of any unplanned shutdowns. Acoustic emissions (AEs) or stress wave monitoring at the bearings has been identifie...
متن کاملOn stability of rotordynamic systems with rotor–stator contact interaction
In machine systems where a rotor spins within a finite clearance space supported by bearings, contact between the rotor and its surround can result in persistent coupled vibration of the rotor and stator. When the vibration response is driven predominantly by friction forces, rotordynamic stability becomes a serious issue. This paper introduces a theory for model-based verification of dynamic s...

Induction machines are perhaps the most widely used of all electric motors. They are generally simple to build and rugged, offer reasonable asynchronous performance: a manageable torque-speed curve, stable operation under load, and generally satisfactory efficiency. Because they are so widely used, they are worth understanding. In addition to their current economic importance, induction motors ...

non-ideality, it will tend to reduce differences between calibraiion and predictior;. To do this of course is not always possible, particularly where the effect of changing dyebath conditions is under consideration, e.g. liquor ratio, electrolyte concentration, pH and dye concentration. To attempt calibration experiments to adequately cover the results of such changes would remove the need for ...
