Zusammenfassung:Induction motors are critical components in many industrial processes. In spite of their robustness they do occasionally fail and their resulting unplanned downtime can prove very costly. Therefore, condition monitoring of electrical machines has received considerable attention in recent years. A suitable model enables motor faults to be simulated and the change in corresponding parameters to be predicted without physical experimentation. This paper presents a mathematical foundation and theoretical analysis of asymmetric stator faults in induction machines. A three-phase induction motor is simulated with simple differential equations. Experimental verification of excitation current under healthy condition is given.
