At EKG (Malaysia) Sdn Bhd, we provide precise and professional motor vibration testing services for air-cooled chillers, ensuring your motor-driven components operate smoothly, efficiently, and without risk of mechanical failure. The motor is a critical part of the chiller system, and abnormal vibration can indicate issues such as imbalance, misalignment, electrical faults, or bearing wear—all of which can impact performance and lead to costly breakdowns.
Detects early signs of motor wear or failure
Prevents unexpected shutdowns and equipment damage
Enhances energy efficiency and system reliability
Supports predictive maintenance strategies
Extends the lifespan of motors and connected components
Motor Rotor and Shaft Balance
Motor-to-Compressor or Fan Coupling Alignment
Bearing Condition and Housing Stability
Electrical Motor-Related Vibration Harmonics
Mounting Base Integrity and Looseness
Visual and Mechanical Inspection
We begin with a full assessment of the motor housing, mounts, shaft, and couplings to check for visible wear or instability.
Sensor-Based Testing
We install triaxial accelerometers and vibration sensors on key points of the motor to measure vibration amplitude and frequency across multiple axes.
Data Analysis
Using tools like FFT (Fast Fourier Transform) and time waveform analysis, we identify:
Shaft misalignment or imbalance
Bearing wear or friction
Electrical resonance or unbalance (especially in VFD-driven motors)
Mechanical looseness or mount degradation
Reporting and Recommendations
You receive a detailed report that includes:
Measured vibration levels and severity
Root cause of any detected issues
Recommended corrective actions such as alignment, bearing replacement, rebalancing, or mount adjustments
Reduces operational risk and energy waste
Prevents motor burnout and mechanical breakdowns
Enhances system performance and cooling consistency
Allows timely maintenance planning
Ensures compliance with HVAC reliability standards
HVAC experts specializing in vibration diagnostics for motors and rotating systems
