Five major problems of air compressor motor

Overheating is the most common cause of motor failures in air compressors. In theory, the service life of the winding insulation will decrease every time the heat is increased by 10°C. Therefore, it is important to ensure that the motor of the air compressor operates at a suitable temperature.

Of course, various floating particles in the air will enter the inside of the air compressor motor and cause various injuries inside. Corrosion particles are likely to damage components, and conductive particles are likely to interfere with component currents. Once the particles block the cooling channel, they will accelerate the overheating. When purchasing the motor of the air compressor, select the appropriate IP protection level.

Harmonic currents caused by high-frequency switching and pulse width adjustment may cause distortion of the operating voltage and current, load and overheating. In turn, the service life of motors and components is shortened, and the cost of long-term machinery and equipment is increased. In addition, the surge itself can cause the operating voltage to be too high or too low. To deal with this problem, we must focus on the power supply situation.

Moist air will corrode the components of the air compressor motor. Of course, there is water in the air, that is, air humidity. When the damp and cold air is mixed with particulate matter, it will also cause fatal damage to the air compressor motor, which will further reduce the service life.

The lubrication of air compressors is a big problem. Too much lubrication or insufficient lubrication will cause damage to the motor. In addition, you must also pay attention to the choice of lubricants, do not use poor quality lubricants, and lubricants of different standards cannot be mixed.
