Evaluating Motor Health
Motor Circuit Evaluation (MCE) is a type of off-line testing that yields indicators for motor health. Motor testing is an essential part of maintenance. Motors that sustain core damage cannot perform optimally — if they continue to work at all. Identifying problems early with motor circuit evaluation prevents permanent damage and has many benefits, including:
Motor circuit evaluation can also diagnose insulation system health, eccentricity, broken or faulty rotor bars, and defective motor connections. Motor testing with RTS includes polarization indexing and a standard AC motor test.
Polarization indexing tests the integrity of a motor stator’s insulation system. This de-energized test plots and trends resistance to ground readings. The data generates a ratio measuring the insulation system’s ability to prevent charge from leaking to ground. The results can indicate whether the motor should undergo an overhaul cycle.
Standard AC Motor Test
A standard AC motor test with RTS assesses capacitance to ground, resistive balancing, resistance to ground, and motor winding balancing. The test looks at key indicators of overall motor health and cleanliness. Paired with polarization indexing, the motor test takes a clear snapshot of insulation system conditions and motor stator winding.
