How to identify DC brushless motors and brush motors

1. The difference between a brushless DC motor and a brush DC motor. Generally, the drawing of the motor can be seen. The rotor of the brushless motor does not require an external power supply, so there is no due to the lead of the king; The power supply, so there are two power cords (DC). The leading line on the stator cannot see the difference.

2. Compared to the brush motor, the continuous working time of the brushless motor will be long, because the brushless motor does not need to change the carbon brush; the carbon brush of the brush motor will wear It is necessary to replace it to ensure that the normal turtle shrinks of the sensor. So their continuous working time is large.

3. Note: The length of the continuous working time is not to represent the service life of the motor! The continuous working time of the theory is not to say that the life of the motor is long! Normally use time. For example, the quality of the winding process of a brushless motor is not high, so the first bad motor is a brushless motor, not a brush motor.
