Electric Motors Inspection

When motors malfunction due to attrition or overheat, it will compromise the performance of the entire production line.Thermal imaging cameras can be used to efficiently and reliably inspect motors malfunctions.


Customer’s Challenge

Electrical motors plays an important role in automation production line, the heart of modern mechanical manufacturing industry. The motors in automation lines usually operate 24/7.


When motors malfunction due to attrition or overheat, it will compromise the performance of the entire production line. And, according to maintenance data statistics, the electric motors lifetime will be reduced half, by its surface temperature raised 10 °C.


While, traditional maintenance methods such as vibration analysis or thermal probing are either inefficient or unreliable.


The Solution

Thermal imaging cameras can be used to efficiently and reliably inspect motors malfunctions. Most issues of a motor system, including lubrication issues, misalignments, overload, aging, mechanical damage, attrition, overheat and circuit shortcut, will manifest themselves in the form of temperature abnormality.


Advanced handheld thermal camera FOTRIC 348A/346A/326M with 40mk of sensitivity, can not only measure surface temperature accurately, but also record historic thermal distribution image data, to perform trend analysis, therefore determine if and when the system requires maintain or replacement.



The Result

Firstly, by using FOTRIC non-contact thermal inspection method, engineers do not need to stop production during maintenance, and can quickly get analysis result by one shot.

Normally, After those faults are detected, engineers will use more professional test tools for deeper diagnose.


With more efficient and reliable periodically maintenance, factory automation line’s production rate are highly improved, and therefore brings more financial returns to users.
