E-Max Motor Testing

Comments (0) Services

Advantage Reliability Services, Inc. provides EMAX Motor Testing as a non-intrusive diagnostic technology for electric motors.  This allows assessment of rotor condition in induction motors as tested under normal operating conditions — without shutting down the equipment.

Specifically, spectral analysis is performed at the first and fifth harmonics of the frequency, yielding current imbalance expressed a percentage under load and impedence imbalance as a trendable measure of stator condition.  Process analysis with motor current analysis, along with voltage, power, and efficiency data are measured, allowing for the testing and monitoring of five major fault zones:

  • Stator
  • Rotor
  • Air Gap
  • Power Quality
  • Power Circuit

Each motor fault zone is categorized after each test, and analysis allows for the definition of problems and isolation of root causes. Production will not suffer downtime for testing, and root cause analysis will provide a proactive approach to maintenance, ultimately saving both time and money.
