Vibration problems in induction motors can be frustrating and may lead to greatly reduced reliability. It can vary from a mere nuisance to an indication of imminent motor failure. With solid knowledge of motor fundamentals and proper diagnostic procedures of vibration analysis, it is possible to identify and pinpoint the root cause of the problem, and more significantly correct, or ascertain the impact of increased vibration on motor reliability and longevity. Hereby below described research will monitor and analyse centrifugal pump and electric motor vibration signal evaluation as overall velocity, hi resolution velocity, shock pulse and bearing envelope measurements change for period more than one year. Task was based to discover how precise is our measurement techniques and how early we are warned about future damage to happen.
