An electric power motor breaks down

THE CONTEXT

The policyholder was asked to overhaul a 1350-hp electric motor used at the production site of a leading tyre manufacturer.
Repairs to one of the parts of the motor were partially subcontracted because the company did not have the highly specific welding technology expertise.

GM CONSULTANT INTERVENTION

The joint appraisal of the parts of the damaged motor carried out by the GM Consultant loss adjusters made it possible to pinpoint the source of the damage. The quality of the welding connecting the winding mechanism of the rotor to the rotary collector was inadequate.

The welding involved specific technology and had been subcontracted. The subcontractor acknowledged that the work had been assigned to an unsupervised apprentice.

The motor was repaired.
