The DC brushless motor is widely used, many places have to use it, some friends in the purchase of brushless motor, it is more worried about its service life, in fact, this is also most people are more concerned about, so what are the factors that affect the service life of DC brushless motor?Vacuz briefly give you an introduction to it!

Because DC brushless motor often have to bear a relatively large load and keep running, so its life can be used for how long, roughly from the motor itself, human factors, environmental factors to consider, the following to analyze.

A, brushless DC motor itself factors

1. bearing is an important part of the motor operation, DC brushless motor without carbon brushes, the bearing has become a relatively easy part of the bad, good quality bearings will generally have a higher life.

2. Rotor magnets demagnetization. DC brushless motor use longer, the magnetism on its magnets will gradually disappear.

3. Stator coil problem. Generally speaking, the motor’s coil aging time are more than 10 years, usually in the process of use, pay attention to keep the coil temperature is not too high, and ensure good heat dissipation to increase the service life of the coil.

Second, human operation factors

Due to the motor in the process of use, the operation of the motor of different technical levels of personnel, resulting in motor misoperation. For example, the motor just started and stopped; overload start; and start when the fault, these will damage the brushless motor and affect its service life.

Third, environmental factors

Brushless motor should be used in a ventilated, dry, non-corrosive gas and normal air temperature and pressure environment. If there are corrosive gases and high humidity in the harsh environment, it is easy to be affected by the environment, which will damage the electrical and mechanical properties of the motor.

As DC brushless motors often have to withstand relatively large loads and keep running, so its life can be used for how long, roughly from the motor itself, human factors, environmental factors to consider, the following to analyze.
