MER Division deals with revisions, repair, refurbishment, up-grade and any intervention on any kind of electric machine, regardless the origin, using the same standards and engineering practice as for new motors manufacturing.
Quality system is notified by INSEMEX Petrosani with care for designing, manufacturing and repair off electric motors for hazardous locations.
Range of operations specific for electric machines:
- stator and rotor coil manufacturing
- windings
- vacuum and pressure impregnations
- test and rehabilitation of magnetic cores
- rehabilitation of structural parts (frames, shafts, endshields)
- repair or replacement of commutators, slip rings, brush-holders, dynamic balancing
- bearings replacement
- non-distructive tests
- complete electric tests
Interventions range:
- from minor operations up to complete refurbishment and up-grade of machines
Up-grades include, but not limited to:
- placing thermal sensors in winding and bearings (Platinum RTD’s or PTC thermistors, associate the RTD’s with transmitters)
- modifications of the cooling system
- bearing insulation
- mounting space heaters
- vibrations sensors
