MOTOR CURRENT SIGNATURE ANALYSIS

MOTOR CURRENT SIGNATURE ANALYSIS

Motor Current Signature Analysis (MCSA) is a condition monitoring technique used to diagnose problems in induction motors. MCSA is simply the process by which motor current readings are recorded and analyzed in the frequency domain. It is rapidly gaining acceptance in industry today. Tests are performed online without interrupting production with motor running under the load at normal operating conditions.





MCSA is used to detect the following defects in Motors.

• Static/Dynamic Air-Gap irregularities
• Broken rotor bar or cracked rotor end-rings
• Stator Faults (Opening or shorting of one coilor more of a stator phase winding)
• Abnormal connection of the stator windings.
