Valuable predictive maintenance tool for recording and analyzing motor current readings in the frequency domain to detect electrical and mechanical faults.

Motor current signature analysis (MCSA) has proven to be a highly valuable predictive maintenance tool. Although it is a relatively young, rarely utilized technology, it is rapidly gaining acceptance in industry today.

MCSA is simply the process by which motor current readings are recorded and analyzed in the frequency domain. It has been around since 1985 and proven itself well over the years in locating rotor faults and air gap problems in motors.

  • Mechanical faults related to belts, couplers, alignment and more are easily found through the use of a demodulated current spectrum.

Identifying core and structural anomalies within electrical motors.

  • Static and/or dynamic air-gap irregularities
  • Broken rotor bar or cracked rotor end-rings

New construction works in built-up urban areas or adjacent to sensitive buildings require strict compliance and safety measures.

  • Specifying vibration limits as part of contracts
  • Providing peace of mind and ensuring vicinity safety

Pinpointing mechanical friction, structural rubbing, and component degradation.

  • Bent shaft (akin to dynamic eccentricity) causing rubs between rotor and stator
  • Bearing and gearbox failures
