Suction Machine Motor Winding Burn Issue (Real Case + Solution Guide)

 

🔧 Introduction

In the biomedical field, even new machines can sometimes develop serious faults. In this blog, I am sharing a real case involving a suction machine that failed within just two months of use.

⚙️ Case Description

I was called to inspect a suction machine in a hospital. The machine was almost new, only around two months old.

During the initial inspection, the suction performance was unstable and not working properly.

After further checking, I found that the motor winding had burned, which is a major internal fault.

❗ Problem Analysis

There can be several reasons for motor winding failure:

Manufacturing defect

Voltage fluctuations

Overloading or continuous usage

Internal component failure

Since the machine was very new, the most likely cause in this case was a manufacturing defect.

✅ Solution & Recommendation

In this situation, I advised the hospital staff clearly:

Do not proceed with repair ❌

Check the warranty status ✔

As the machine was under warranty, the best approach was:

Contact the manufacturer

Claim warranty support

Request replacement instead of repair

💡 Key Learning

This case highlights an important lesson:

Not every problem should be fixed by repair

Always check warranty before taking action

A biomedical engineer must make smart and cost-effective decisions

🏥 Conclusion

A suction machine is a critical life-saving device, and faults should never be ignored. If the equipment is under warranty, replacement is often the safest and most reliable solution.
