When an HVAC pump motor burns out, the heat from the failure often damages the core laminations and degrades the original copper winding quality. Standard, low-cost rewinding often results in a significant drop in motor efficiency, leading to higher electricity bills and a shorter lifespan. EKG (Malaysia) Sdn Bhd specializes in Energy-Efficient Motor Rewinding, utilizing high-grade materials and precision techniques to restore your motor to its peak performance—sometimes even exceeding its original factory efficiency.

Burnt Smell or Smoke – Indicates a catastrophic failure of the winding insulation.
Frequent Tripping – Short circuits within the coils causing the circuit breaker or overload relay to trigger.
Low Insulation Resistance (Mega Test Failure) – Moisture or heat has compromised the integrity of the internal copper coatings.
Excessive Heat During Operation – Current is leaking between windings, creating localized "hot spots."
Humming Without Starting – A symptom of a single-phase failure or a shorted winding segment.
To remove old windings without damaging the motor's stator core, we use temperature-controlled ovens. Excessive heat during the "burn-off" phase can warp the iron laminations, permanently destroying the motor's efficiency. We ensure the core integrity is preserved.
We use 99.9% pure oxygen-free copper wire with a higher "fill factor" (more copper in the slots) to reduce electrical resistance. We utilize Class H Insulation (rated for 180°C), providing superior thermal protection compared to standard Class F materials.
We use premium resins and specialized varnishing techniques to eliminate air pockets within the windings. This improves heat dissipation and prevents the vibrations that lead to "winding rub" and premature failure.
Before and after rewinding, we can conduct core loss tests to ensure the magnetic properties of the stator have not been compromised. This ensures the motor maintains its IE2 or IE3 efficiency rating.
A rewound motor is only as good as its mechanical assembly. We replace bearings with premium-grade SKF/FAG units and perform dynamic balancing on the rotor to ensure vibration-free operation, which protects the new windings from mechanical fatigue.
Every rewound motor undergoes a comprehensive "Run-Test," measuring Amp draw, voltage balance, and temperature rise to ensure it is ready for the demands of 24/7 HVAC duty.
Efficiency First Approach – We focus on reducing "I²R" losses (copper losses) to keep your energy bills low.
ISO-Certified Quality – Our workshop follows strict international standards for electrical machine repair.
Rapid Turnaround in Selangor – We provide fast collection and delivery to minimize your cooling system's downtime.
Turnkey MEP Capability – We can dismantle the pump, pull the motor, rewind it, and perform laser alignment upon reinstallation.
Don't settle for a sub-standard rewind that costs you more in energy over time. Trust EKG (Malaysia) Sdn Bhd for high-quality, energy-efficient HVAC pump motor rewinding. Our expert team will ensure your motors are restored with the precision and durability required for Malaysia's industrial and commercial environments.
