Advantages and Common Faults of Brushless Motor and Brush Motor

Author:


Brushless motors and brushed motors have their own unique advantages, but there may also be some common faults.

Brushless motor advantages:

1. High efficiency and energy saving: The brushless motor uses electronic commutation instead of traditional mechanical commutation, which makes the motor more efficient and consumes less energy.

2. Long life: Due to the simple structure of the brushless motor, the mechanical wear is reduced, so the life is longer.

Low noise: the operation of the brushless motor noise is relatively small, making the use of the environment more quiet.

4. Good speed regulation performance: Brushless motor can realize precise speed regulation through electronic control, which is suitable for occasions that require precise speed control.

brushless motor common fault:

1. Controller failure: The controller of the brushless motor may fail, causing the motor to fail to work normally.

2. Hall element damage: The Hall element in the brushless motor may be damaged due to overload or high temperature, which affects the normal operation of the motor.

Brush motor advantages:

1. Simple structure: The structure of the brush motor is relatively simple and the manufacturing cost is low.

2. Convenient maintenance: The maintenance of the brushed motor is relatively convenient because its mechanical parts are easier to access.

3. Large starting torque: Brush motor has a large torque when starting, which is suitable for occasions requiring large starting power.

brush motor common fault:

1. Brush wear: The brushes in the brush motor will gradually wear out with use and need to be replaced regularly.

2. The commutator ablation: brush motor in the commutator may appear ablation phenomenon, affecting the normal operation of the motor.
