Five Killer Of Electric Motor Breakdown

1.Overheat

The most of motor breakdown reason is overheat.Theoretically, for every 10°C increase in heat, the life of the winding insulation is halved.Therefore, ensuring that the motor operates at the right temperature is the best way to extend its life.


2.Dust and Pollution

Various types of suspended particles in the air can enter the interior of the motor and cause various hazards. Corrosive particles can wear parts and conductive particles can interfere with component currents. Once the particles block the cooling channel, they will accelerate overheating. Obviously, choosing the right IP protection level can alleviate this problem to some extent.


3.Power Supply

Harmonic currents caused by high-frequency switching and pulse width modulation can cause voltage and current distortion, overload, and overheating. This shortens the life of motors and components and increases long-term equipment costs. In addition, the surge itself will cause the voltage to be too high and too low. To solve this problem, we must continue to pay attention to and check the power supply status.


4.Humidity

Humidity itself will erode motor parts. When the moisture and airborne particulate contaminants mix, it is fatal to the motor, further reducing the life of the pump.


5.Improper lubrication

Excessive lubrication or insufficient lubrication can cause harm. In addition, we must pay attention to the problem of contamination in the lubricant and whether the lubricant used is suitable for the task at hand.
