How do you measure the goodness of a DC brushless motor? What are the common methods?

The application of DC brushless motor is more and more widely used, the market model is also more and more, the price is also gradually reduced, of course, there must be bad products mixed in, some of them can not be used for a long time on the strike, then how to correctly measure the good and bad DC brushless motor? What are the common methods?

Generally speaking, to measure the good and bad DC brushless motor, these methods can go to try to rule out:

1. Rotation test: manually rotate the motor shaft, pay attention to any abnormal sound or resistance. If the motor rotation difficulty or hissing sound, may indicate that the motor has a problem. 2.

2. Current test: Use a multimeter to measure the motor’s operating current at a given voltage. If the current is high, it may indicate an internal short or high voltage in the motor.

3. Insulation Test: Measure the insulation resistance of the motor with a multimeter or insulation tester. If the resistance is too low, it indicates that the motor has internal leakage and needs to be repaired or replaced.

4. Magnetic Pole Test: Use a multimeter or Hall effect sensor to test the motor’s magnetic poles to see if they are normal. If the electrodes fail or the motor position sensor does not work, the motor will not work properly.

In summary, careful testing and diagnosis of the motor will reveal any problems within the motor to determine if the motor needs to be repaired or replaced.
