Five major factors leading to motor failure

Update:2018-01-15

A number of factors lead to motor failures, and five of the most common reasons are listed below. However, if the motor is properly used and maintained and the environment is properly managed, these problems can be prevented.
1. Overheating
Overheating is the biggest cause of motor failure. In fact, the other four reasons listed in this article are on the list, partly because they produce heat. In theory, the life of the insulation of the winding will be halved by each increase of 10 C heat. Therefore, it is the best way to prolong the life of the motor at the right temperature.
2. Improper lubrication is a problem of one degree. Excessive lubrication or insufficient lubrication can cause harm. In addition, we should also pay attention to the pollution problems in the lubricants, and whether the lubricant used is suitable for the task at hand.
3. Power supply problem
The harmonic current caused by high frequency switch and pulse width modulation may lead to voltage and current distortion, overload and overheating. Thus, the life of motor and components can be shortened, and the cost of long term equipment is increased. In addition, the surge itself can cause high and low voltage. To solve this problem, we must continue to pay attention to and check the status of power supply.
4, humid
Moisture itself will corrode the motor parts. When the particle pollutants in the air are mixed together, it is a fatal injury to the motor and further shortens the life of the pump.
5, the dust and all kinds of suspended particles in the polluted air will enter the motor and produce various kinds of harm. Corrosive particles may wear parts, and conductive particles may interfere with the component current. Once the particles block the cooling channel, it will accelerate the overheating. Obviously, the choice of the right IP protection level can alleviate the problem to a certain extent.
These problems are interrelated, and it is difficult to deal with one of them alone. At the same time, these problems also have a common point: if the motor is properly used and maintained and the environment is properly managed, these problems can be prevented.
