Motor/Generator Repair & Maintenance
Electrical maintenance programs are designed to increase equipment promptness and uptime while decreasing capital operating cost. Electric Motor Testing is usually the first thing to be sacrificed when cutting back on operational expenses.
Motor/Generator Repair & Maintenance
Full overhaul, winding repair and planned maintenance for low and high voltage motors and generators in service.
Overhaul
- De-coupling of the motor
- Dismantling of all removable cabling
- Thorough cleaning of stator and rotor
- Varnishing of stator and rotor windings
- Bearing replacement
- Fitment, assembly and re-coupling
- Post-overhaul testing before return to service
Planned maintenance
- Scheduled inspection and written condition reporting
- Bearing condition monitoring through vibration analysis
- Insulation resistance and polarisation index trending
- Thermographic survey of terminations and enclosures
- Terminal box, cable and earthing inspection
- Cooling system and fan cowl cleaning
Repair driven by diagnosis
Because bearing failure and electrical faults are the two dominant failure modes, a repair that addresses only the symptom tends to be a repair you do twice. Testing establishes what actually failed and why before any work is quoted, which is the difference between replacing a bearing and finding the misalignment that destroyed it.
