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.
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
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)
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
Saves on costly full compressor or motor replacements
Improves system energy efficiency and performance
Minimizes downtime and service disruption
Ensures safe operation and electrical reliability
Supports preventive maintenance and long-term planning
Specialists in chiller motor diagnostics and repair
Equipped with precision tools and certified repair techniques
Experience across scroll, screw, and reciprocating compressors
Familiarity with all major air-cooled chiller motor brands and types
Complete support from fault diagnosis to recommissioning
A failing compressor motor doesn’t mean replacing the whole unit. With EKG M&E Sdn Bhd’s air-cooled chiller compressor motor repair service, you can restore power, efficiency, and peace of mind. Contact us today to book a diagnostic inspection or motor repair service.
