Air-gap eccentricity is a fault that mainly affects large induction motors. In the worst case an eccentricity fault can result in a stator rotor rub thereby causing severe damage to the motor. As a result eccentricity fault detection has gained considerable significance. Of all detection schemes for this fault, Motor Current Signature Analysis (MCSA) is the most widely used technique. This scheme...
Induction motors are most popularly used in modern day industrial drives. Under operating stresses and ageing, both stator and rotor of an induction motor undergoes degradation. It is necessary to properly assess the condition of motors on operation for reliable performance. Popularly employed technique for motor condition monitoring is the motor current signature analysis (MCSA) that deals with frequency...
