Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems. It is the case of corrosion and reduce the equipment lifetime. Therefore usually the additional air treatment equipment, like air dryer are used to avoid the accumulation of moisture in the pneumatic system.

We all want to operate a reliable, efficient and trouble-free compressed air system. Following the equipment manufacturer's daily and weekly maintenance checks can help you to deal with this problem. After all, prevention is better than cure! For many companies, compressed air is considered to be very important for plant operations. Air compressors are high-value machines if it is not well maintained, resulting in high energy costs, the machine can get unexpected incidents affecting the production schedule and even damage the product.

How to detect failures of  air compressor motor

 Currently, Most air compressor using 3-phase asyncronous motor( high capacity air compressor)  and air compressor using 1 phase electric motor( low capacity air compressor). Druring using and operating time , there are many incidents due to electric motor failure such as: Short circuit, electric motor fire, clogged motor, low load, excessive vibration and quick-heated machine. When you connect to  the power supply, the protective equipments are reacted immediately ( Contactor is broken. Engine runs with sufficient speed but 3 phase electric current is unbalanced ...In order to help you earlier detect symptoms, causes and remedies, this article is recommended.

Air compressor motor 

1.Some common failure of 3 phase asyncronous motor.  
 

1.1 Motor is quickly overheated, groaning and unable to start when connecting to power supply ( slowly spin or not spin).

- Causes :
+Power supply  loses 1 phase
+ Inner phase of stator is broken 
+ Bearing is worn out so  rotor is clogged 
- Remedies 
+ Check and repair 
power supply wiring, fuses, contactor, main switch
+Measure and check each phase and repair brokren position. 
+ Check the loose of bearing. Repair or replace bearing 

1.2 The protective equipment are reacted immediately after power connection

- Cause 
+ Stator is short-circuited
- Remedies :
+ Check and repair the short-circuited phase. 

1.3 Engine runs with insuffcient speed, strong vibration, quickly -overheated.  
- Causes 

+  Short circuit in Inner coil  
+
The engine is destroyed
- Remedies:
+ Check wirings by Gronha , if it is internaly short-circuited , wrap it. 
+ Recalibrate or replace new bearing .

1.4 Mechanical sound, current is abnomal increase.
- Causes 
+ The cap is not well-fixed to the machine
+Bearing is worn out, shaft is curvied.
- Remedies :
+ Repair and correct mechanical parts.
+ Replace bearing 

1.5 Engine runs with sufficient speed but 3 phase electric current is unbalanced (deviation more than 10% in each phase)
-Causes 
+ Short circuited phases 
- Remesies:
+ Check source voltage  điện áp nguồn
+ Check short-circuited position.
1.6 
The load current is not too high Io> 50% Iđm
- Cause 
+ Poor quality circuit
+ Many winding is shorted-circuit 
- Remedies 
+
Enhance drying. If there is a change, it can be useD, If not it  must be corrected
1.7 Engine can not start while loading 
- Causes 
+ Heavy load 
+ Decrease sourse voltage 
+ Phase loss
- Remedies 
+ Decrease load 
+ Check the sourse voltage 
+ Check power supply
