Why Does a Blower Still Vibrate After Dynamic Balancing? It is a common and frustrating situation in industrial maintenance. Your blower wheel has passed dynamic balancing on the balancing machine. The balancing report shows an acceptable residual unbalance, yet after installation, excessive vibration is still present. So, what went wrong? The answer is that dynamic […]

Bearing Failure Is Often the Symptom, Not the Root Cause Replacing the Bearing Does Not Solve Every Bearing Problem Bearing replacement is one of the most common repair activities in rotating equipment. However, replacing the failed bearing without identifying the actual cause often results in repeated failures. A proper Root Cause Analysis (RCA) investigates the

Why Insulation Resistance and Winding Resistance Tests Cannot Detect Every Motor Winding Defect Not Every Winding Defect Causes Immediate Failure Insulation Resistance (IR) and Winding Resistance tests are essential electrical tests performed during motor maintenance. However, many people assume that if a motor passes both tests, the winding is completely healthy. Unfortunately, this is not

Can a Motor Perform at Its Original Efficiency After Rewinding? A common question in industrial maintenance is:“Can a rewound motor still perform at its original efficiency?” With Malaysia’s MEPS 2027 efficiency standards approaching, understanding how rewinding affects performance is essential for both compliance and cost savings. What Happens During Rewinding? Rewinding involves removing damaged coils

Why Electric Motors Sometimes Encounter Random Tripping That’s Hard to Recognize Unexpected or “random” tripping of an electric motor can be one of the most frustrating issues in industrial operation. It often occurs without clear symptoms — the motor restarts and runs fine for hours or days before it happens again. These intermittent faults are

Common Electric Motor Failures — And How We Overcome Them 1. Overheating and Insulation Breakdown Root Cause: Continuous overloading, poor ventilation, or unbalanced voltage supply often causes temperature to rise beyond insulation limits.Effect: Insulation hardens and cracks, leading to short circuits or phase-to-phase faults.Our Solution:At TE Teras Tech, we perform Motor Circuit Analysis (MCA) to
