Electric Motor Services
Our services range from standard inspections and overhauls to complete rewinds. In addition, our engineers are capable of re-engineering and upgrading electric motors to be more efficient and durable.
A repair or overhaul of an electric motor generally consists of an Inspection, Repair/Modification and a final Report.
Inspection
The first step when repairing an electric motor is the inspection. Our electrical test facilities perform an ”In Test” that includes unloaded electrical tests and vibration measurements.
- Visual inspection
- Disassembly + visual inspection of parts
- Dimensional measurements
- Check of probes and sensors (if present)
- Oil sampling & check
- In test
- Electrical (without load)
- Vibration measurement
- Megger test
When the inspection is finished, an inspection report is drawn up with recommendations for repair.
Execution of works
After approval of the recommendations for repair, the execution of the repair / overhaul works begins. The scope of work may vary, but can include:
- Cleaning, steaming and drying
- Sandblasting
- Preparation of technical drawings for machining by in-house engineering team
- Rewinding
- Stator
- Rotor
- Electric brakes
- In-situ Rewinding
- Machining of parts (bearing housings, rotors, motor feet, …)
- If necessary
- Welding of rotors, stators, frames, shaft locks, … with support of engineering team for welding procedures, material analyses and NDT
- Balancing of rotating parts
- Assembly
- Coating of exterior
- Final testing
Final report
The final report is written after testing and includes measurements from before and after the repair. When possible, recommendations for operating, inspecting and maintenance are also included, resulting in more reliable operations and less unforeseen breakdowns.
