However, induction motors are susceptible to many types of fault in industrial applications. A motor failure that is not identified in an initial stage may become catastrophic and the induction motor may suffer severe damage. Thus, undetected motor faults may cascade into motor failure, which in turn may cause production shutdowns.

Such shutdowns are costly in terms of lost production time, maintenance costs, and wasted raw materials. The motor faults are due to mechanical and electrical stresses. Mechanical stresses are caused by overloads and abrupt load changes, which can produce bearing faults and rotor bar breakage. On the other hand, electrical stresses are usually associated with the power supply. Induction motors can be energized from constant frequency sinusoidal power supplies or from adjustable speed ac drives. However, induction motors are more susceptible to fault when supplied by ac drives. This is due to the extra voltagestress on the stator windings, the high frequency stator current components, and the
induced bearing currents, caused by ac drives. In addition, motor over voltages can occur because of the length of cable connections between a motor and an ac drive. This last effect is caused by reflected wave transient voltages [1]. Such electrical stresses may produce stator winding short circuits and result in a complete motor failure.
