The COMPACS®-RPE system for electric motors diagnostics

The COMPACS®-RPE system is a modification of the COMPACS® computer monitoring system and is designed for electric motors after-repair health diagnostics.

The system provides vibration parameters control (vibration acceleration, velocity, vibration displacement), measured in front end and tail motor bearing planes in vertical, horizontal and axial directions, useful current, measured in accordance with voltage phases, front end and tail motor bearings temperature and the motor rotor rotation frequency.

The system has a built-in automatic expert system, which allows an automatic detection of the following malfunctions: defects of inner and outer races, separator, rolling elements, rotor and stator contact, weakening of fitting, enlarged clearance, compressed bearings, end shield misalignment, stator windings defect (electrical imbalance), electric motor rotor imbalance and others.

The COMPACS®-RPE allows to diagnose from 1 to 8 electric motors simultaneously and ensures the electric motors commissioning with a maximal potential resource.

The electric motor quality, evaluated according to digital signal processing and measurement results, are displayed as colored pictograms (green – "ACCEPTABLE", yellow – "MEASURES REQUIRED", red – "UNACCEPTABLE") and diagrams with numerical parameters values.

The system carries out a complete analysis of vibration signals by means of fast Fourier transformation, digital filtering and envelope selection.

The tested equipment data can be saved in the system archive.
