Full overhaul of 132KW 2 Pole IP23 WEG Electric Motor

Motor Details: WEG 132KW 2 Pole 2970 RPM IP23 280S/M-02  

JJ Loughran were recently requested to rewind and overhaul a compressor motor for a critical operation in a food processing factory. The WEG motor in question ran an important compressor application for the factory. At JJ Loughran we believe in the importance of being able to not only supply new motors, gearboxes and drives, but also to repair and maintain equipment to original OEM standards. With our state-of-the-art equipment including an IRD balancing machine and advanced test equipment, we can ensure all repairs are carried out to the highest standards.

It is not always cost effective or sustainable to replace all failed electric motors, for this reason, the JJ Loughran engineering workshop endeavours to ensure that the solutions offered to our customers are always cost effective and environmentally conscientious. 

The full rewind and overhaul process of the WEG 132KW 2 Pole Motor was completed in just under 1 working week, delivering a much faster outcome than replacing the unit in question.

JJ Loughran stock a large range of electric motor spare parts, including SKF bearings, seals, terminal blocks, rewind copper etc. We also have a machining department which can manufacture, new shafts, coupling, fans and other critical electric motor parts as required, thus enabling our engineers to carry out quick turnarounds on mission critical pieces of equipment.

The work carried out on the WEG 132KW 2 Pole 2970 RPM IP23 280S/M-02   was as follows: -

  1. Mechanically dismantling motor into individual parts
  2. Electrically Inspect unit
  3. Measure mechanical dimensions on front & back endcaps to ensure within machine tolerances
  4. Clean all individual parts
  5. Complete rewind of stator
  6. Varnish and stove stator
  7. Dynamically balance rotor
  8. Replace bearings with new SKF units
  9. Reassemble & test run motor
  10. Clean & respray unit back to original OEM paint specification
  11. Deliver equipment back to site.

We utilised our advanced test equipment,  to carry out the following tests before and after the overhaul to ensure the quality of the repair and to verify that all motor parameters were nominal and within manufactures tolerances. This gave our customer confidence that the Electric Motor was overhauled to the highest standard. See attached balancing report and Electrical test report, in which the following tests were conducted.

  • Resistance
  • Meg-Ohm
  • Surge
  • DC continuous ramped
  • Step-voltage
  • Polarization index (PI)
  • Dielectric analysis
