A brushless motor is a kind of motor that uses an electronic commutator to control the speed and torque of the motor, it does not have carbon brushes and a commutator, so it has the advantages of high efficiency, low noise, low maintenance, and long service life, etc. Therefore, it is widely used in many fields, such as aviation, industry, and automobile. Therefore, brushless motors are widely used in many fields, such as aviation, industry, automobile, etc. Therefore, its performance test and reliability are especially important.

I. Brushless motor failures:

Brushless motors are the best tools that can be used for a wide variety of applications, but brushless motors are subject to a variety of malfunctions, as follows:

■ Hall failure

■ Controller damage

■ Motor wire contact failure

■ Out of phase

■ Motor winding overload

■ Loose winding

■ Dirty commutator

■ Bad bearing

■ Degradation of winding insulation breakdown

■ Motor bearing failure

■ Excessive vibration or noise

Ⅱ. Brushless motor test

A brushless motor performance test is very important, it determines the quality of the motor test, AIP has been focusing on brushless motor tests for many years, and now we have some perfect BLDC motor testers.
