Electrical tests include winding resistance, insulation resistance and polarization index, surge comparison, high-potential testing, core-loss and hot-spot detection using high-capacity core-loss test equipment, and partial-discharge screening on medium and high voltage windings.
Mechanical and operational tests cover no-load solo runs up to 4,000 kW, vibration analysis and spectrum diagnosis, bearing temperature trending, shaft run-out and full dimensional inspection with calibrated Mitutoyo instruments.
Motor Current Signature Analysis (MCSA) and online condition monitoring detect rotor-bar, eccentricity and bearing faults in machines that are still in service, so maintenance can be planned instead of forced.
What is included
AC / DC motor solo runs
No-load running tests up to 4,000 kW with current, vibration and temperature recording.
Core-loss & hot-spot testing
Loop testing of stator cores before and after stripping to protect the lamination stack.
Electric winding analysis
Resistance, insulation, polarization index, surge and hi-pot with certified reports.
Motor current signature analysis (MCSA)
Non-intrusive detection of rotor and bearing defects on running machines.
Vibration analysis
Spectrum and phase analysis, imbalance, misalignment and looseness diagnosis.
Mechanical dimensional inspection & profiling
Shaft, housing, bearing-fit and air-gap measurements against OEM tolerances.
