Evaluation of the stray load losses for a three-phase induction motor

Nagornyy, Aleksandr S. 13 June 2003 (has links)
The evaluation of the stray-load losses in induction motors is an important part of the efficiency estimation process. However, stray-load losses have several components which are difficult to isolate and calculate. Consequently, they are more readily determined by test. IEEE Standard 112-1996 recommends the testing of electrical induction motors at a rated mode (nominal frequency and voltage). Thus, the IEEE 112 test does not provide us with information about the motor efficiency and stray load losses at supply frequencies which are different from the rated value. At the same time, this information is very important for the correct evaluation of the efficiency of the motors, controlled by the Adjustable Speed Drives (ASDs). This work is dedicated to the investigation of the relation between the motor efficiency, stray-load loss and the supply frequency. The voltages to be applied for the specific values of the frequency were chosen to keep the value of the relative slip constant at 100% load torque. After performing the series of load tests, it was found that the SLL is proportional to the square of the load and the dependency between SLL and frequency for different load levels is close to linear. The comparison of the efficiency values obtained by the methods IEEE 112 B and 112 E has shown a good correlation of the results. / Graduation date: 2004
