dc.description.abstractAsynchronous motors are frequently used in many industrial applications, especially pumps andfans. Placement, bearing and coupling faults are common faults in these types of engines.Misalignment error is a common type of error that is seen very often among these errors. This errormay cause efficiency decrease in a short run and vibration may cause short circuit and wear inmoving parts in the stator windings in a long run. Early diagnosis of such faults is important interms of machine health and productivity. In this study, loose connection and angular imbalanceof the asynchronous machine were investigated. In the experimental works, a 1 Phase 0.75 KWpower asynchronous motor, Y-0036-024A Electromagnetic Brake and SKF Microlog vibrationmeter were used during the measurements. The Frequency components of motor caused by thesettlement errors were investigated under the different loads. A loose assembly error and angularimbalance were investigated from the misalignment errors. The engine was run idle and withoutany positioning errors and measurements were taken from different points with the accelerometerand the frequency spectrum examined. Measurements are repeated when the misalignment errorsare occurred on purpose and the FFT frequency components were compared under the load of12.50Nm using magnetic brake. The results show that the FFT frequency components areexamined and the placement error can be determined with high success and accuracy. It has beenfound that harmonic components are formed in the frequency spectrum at 25Hz Coefficients. Afterthe settlement error is generated it is seen that, undesired frequency components that are unloadedare lowered under load when the frequency spectra is examined. In this study, theoretical andexperimental comparisons of settlement errors are made. Although many errors in this subject areexamined in the same publication in general, only the results of the settlement errors are examinedspecifically as a contribution to the literature. The results and graphs are presented comparativelyto the reader's knowledge.
