Sažetak

Under normal operating conditions, induction motors reach a higher temperature value than the initial operating temperature. The higher this temperature value is, the more the losses in the motor increase, negatively affecting the performance of the motor. The increased heat needs to be removed from the motor. There are several ways to do this, the most commonly used of which are the use of fans, fins in the stator frame and fins in the rotor end ring. In this study, the cooling fins in the stator frame of an induction motor were spiraled to create a faulty motor frame. The focus of the study is to experimentally obtain the effects of thermal analysis on the faulty motor body. In addition, performance analyses, vibration analyses and air flow analyses of the motor were performed. These four analyses obtained from the faulty motor were compared with the healthy motor. In order to obtain the data, the motor was tested in no-load, short circuit and loaded operation. The data obtained showed that the temperature values in the faulty motor casing were 6.22% higher in short-circuit operation and 7.95% higher in loaded operation compared to the healthy motor, and accordingly, the performance was adversely affected. The absence of stator fins in the faulty motor caused an asymmetrical distribution of airflow and the difference between inlet and outlet airflow speed decreased by 43%. In addition, it was determined that the faulty motor operated with 1.5-2 times more vibration.
