Electric Motor Rewinding
DKSB Engineering (M) Sdn Bhd provides professional electric motor rewinding to restore performance, reduce overheating, and help your motor run smoothly again. We support motors for pumps, fans, blowers, compressors, and general industrial equipment across Kuala Lumpur and Selangor.
What is included in electric motor rewinding?
Motor rewinding replaces damaged copper windings and repairs insulation inside the motor. It is a reliable option when a motor trips, overheats, smells burnt, or fails insulation tests. The outcome is a safer motor restart and more stable operation.
- Initial inspection and condition check (burn marks, loose connections, moisture signs)
- Winding removal and slot cleaning
- Rewinding with suitable copper wire (matched to motor specification)
- Insulation and varnish treatment (to protect against heat and moisture)
- Bearing check and replacement (if worn or noisy)
- Reassembly and basic functional checks
- Service reporting (findings + recommendations)
To speed up quotation: share motor kW/HP, voltage, phase (1P/3P), RPM, nameplate photo, and what happened before it failed.
Why do electric motors burn or trip?
Many motor failures are predictable. Early action prevents repeated trips, production stoppage, and damage to connected equipment.
Overheating
Blocked ventilation, high load, or poor cooling can overheat windings.
Power issues
Voltage imbalance, loose terminals, or unstable supply can damage insulation.
Moisture & dirt
Water ingress and dust reduce insulation strength and cause short circuits.
Bearing problems
Noisy or tight bearings increase load and heat, leading to winding damage.
Common warning signs: burning smell, repeated tripping, motor too hot to touch, humming without starting, low torque, or unusual noise.
How DKSB performs electric motor rewinding
We follow a clear, documented workflow to help ensure the rewind is done correctly and the motor is safe to return to service. You receive a straightforward report that helps maintenance teams plan the next steps.
Assessment
Check the motor condition and confirm likely cause (heat, power, moisture, bearing).
Rewinding work
Remove old windings, clean slots, rewind with suitable wire, and secure properly.
Insulation protection
Apply insulation treatment and varnish to improve durability against heat and moisture.
Testing & handover
Reassemble, check running condition, and share findings with recommendations.
What you receive after service
- Findings summary (probable cause + observed damage)
- Recommendations to prevent repeat failure (cooling, power checks, environment)
- Before/after notes to support preventive maintenance planning
Practical tip: A rewound motor may still fail again if the root cause remains (for example: poor ventilation, water ingress, or unstable power). We highlight these risks clearly in the report.
Typical scope and downtime for motor rewinding
Downtime depends on motor size, condition, parts availability (bearings, fan cover, terminal parts), and workload. We aim for safe, stable operation after return to service.
| Scope Item | Purpose | Notes |
|---|---|---|
| Winding replacement | Restore electrical performance and reduce overheating risk | Must match motor specification |
| Insulation & varnish | Protect windings from heat, moisture, and dirt | Helps improve durability |
| Bearing check/replacement | Reduce noise and load on the motor | Common cause of overheating |
| Test run | Confirm stable operation before handover | Verifies basic running condition |
For critical equipment, ask about standby planning (swap motor strategy) to reduce downtime.
