True to our will to master all the techniques of our business, and further to investments in equipment and training, YVROUD now carries out maintenance of electric motors in its workshop!

After sandblasting and painting the outer frame, internal actions are as follows:

  • Disassembly of the motor
  • Cleaning mechanical parts
  • Refurbishment of grease lubrication systems
  • Replacement of bearings and greasing
  • Replacement of screws and bolts
  • Refurbishment of the cables’ insulation, if needed
  • Impregnation of the winding
  • Electrical tests:
    – Resistance of windings measurement
    – Insulation resistance measurement
    – Polarisation index
    – Gradual test of dielectric strength
    – Impulse test or shock test
  • Tests on our electric bench
  • Vibration measurement by spectral analysis
  • Dynamic balancing
  • Detailed intervention report

The first customer to benefit from this new service is APRR.
