Production Quality Related Propagating Faults of Induction Machines

This paper presents a study of ten identical induction motor. Due to the wide usage of induction machines in different industries, the maintenance and reliability of such devices is getting a great importance. The main failures of induction motors are listed, as well as the reasons for these failures have been pointed out. A special attention has been paid to manufacturing faults, which usually are not taken into consideration, but can evolve during the motor operation and lead to undesirable consequences.
