- Abstract:
- Some damages of mechanical parts such as bearings, rotor, shaft or the damages in the elements of electromagnetic system, for example in the wiring of stator, rotor or of the magnetic circuit can appear in induction motors. Statistics say that bearings are this part of induction motors which is most susceptible to damage. That is why the issues connected with diagnostics of bearings are so important. This paper shows diagnostic methods which employ the acceleration of vibration measurements. The appearance of a specific kind of damage in the motor is a source of additional forces whose character is oscillatory and which can be noticed in the damaged area. These forces result in vibrations which form the basis for diagnostic research. When the course of these vibrations is subjected to spectral analysis, it can be obtain a number of components related to specific types of damages. A scanning laser vibrometer PSV-400 Polytec has been employed for vibration measurements. The research has been conducted on a number of artificially damaged bearings. This paper presents exemplary results of testing damaged bearings with the usage of laser vibrometer PSV-400. The research of technical condition of the same bearings was simultaneously carried out with DREAM – a vibration diagnostics system.
