Motor Current Signature Analysis is the online analysis of current to detect faults in a single/three phase induction motor drive while it is still operational and in service.
The possible defects caused in motor current signature is Broken Rotor Bar, Numerous Broken Bar, Stator Core and Winding Damage, Broken and Damaged Bars and Core Damage due to excessive heating,
Abnormal Airgap Eccentricity and certain mechanical problems train characteristics.
Problems of Motor Current
Broken/Cracked Rotor Bars
Loose Rotor Bar Joints
Faults of Eccentric Rotor
Stator Eccentricity,Soft Foot Shorted Stator Laminations
Grounding Fault or Tuning Fault
