Air-Cooled Chiller Compressor Motor Repair – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we provide professional compressor motor repair services for air-cooled chillers, ensuring reliable, energy-efficient operation of your cooling system. The compressor motor is the driving force behind the entire refrigeration cycle, and any malfunction—such as winding failure, insulation breakdown, or electrical imbalance—can cause significant performance loss or complete system shutdown.

Why Compressor Motor Repair Is Important

• Restores cooling performance and system operation

• Prevents full compressor replacement and extended downtime

• Reduces energy consumption and overheating risks

• Ensures safe, compliant operation of electrical systems

• Extends the lifespan of the chiller unit

Common Compressor Motor Issues We Repair

• Burnt or shorted windings

• Grounded or open motor leads

• Insulation failure

• Phase loss or imbalance

• Stator or rotor damage

• Faulty start/run capacitors or relays (for single-phase motors)

Our Compressor Motor Repair Process

Comprehensive Motor Diagnosis
We begin with detailed electrical and mechanical testing using:

• Megohmmeters for insulation resistance

• Multimeters and clamp meters for voltage and current checks

• Thermal imaging to detect overheating or phase imbalance

• Motor winding and continuity tests

Disassembly and Fault Isolation
We remove and inspect the motor assembly for internal faults, including burned windings, broken terminals, and mechanical wear.

Motor Repair or Rewinding
Based on the damage severity, we carry out:

• Motor rewinding with high-temperature-rated copper wire

• Stator and rotor reconditioning or replacement

• Repair of terminals, lead wires, and internal insulation

Reassembly and Testing
The motor is reassembled, realigned, and tested under load to verify:

• Proper voltage and current draw

• Balanced phase loading

• Smooth, vibration-free operation

• Compatibility with compressor cycle and control systems

System Recommissioning
Once reinstalled, we test the entire chiller system to confirm:

• Full compressor functionality

• Optimal pressure and cooling performance

• Stable motor operation during start-up and load

Benefits of Compressor Motor Repair
