Study on the Life Prediction of Induction Motors Based on Accelerated Degradation Testing Method
Induction motors are widely used in industry, and usually have a long life. To predict the life and reliability of the motors within a reasonable time, a simple and available accelerated degradation testing method is presented. To simulate the unbalanced load on the motor, the lamina with circular holes is mounted on the shaft of the motor eccentrically, and different unbalanced loads are obtained by changing the mounted places of the lamina. A motor accelerated test with three kinds of stress is applied, and the Orbit Areas are used to reveal the performance degradation index of motor. The life and reliability of the motor is finally predicted and evaluated with a balanced lamina mounted on the shaft as its normal working condition. The accelerated degradation testing approach has been proven to be practical to predict the life of the motors.
