Advantages and common faults of brushless motors and brushed motors

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

Advantages of brushless motors:

1. Efficient and energy-saving: Brushless motors use electronic commutation instead of traditional mechanical commutation, making the motor more efficient and consuming less energy.
2. Long lifespan: Due to the simple structure of brushless motors, mechanical wear is reduced, resulting in a longer lifespan.
3. Low noise: The operation noise of brushless motors is relatively small, making the usage environment quieter.
4. Good speed regulation performance: Brushless motors can achieve precise speed regulation through electronic control, suitable for situations that require precise speed control.

Common faults of brushless motors:
1. Controller malfunction: The controller of the brushless motor may have malfunctioned, causing the motor to malfunction.
2. Hall element damage: Hall elements in brushless motors may be damaged due to overload or high temperature, affecting the normal operation of the motor.

Advantages of brushed motors:
1. Simple structure: Brushed motors have a relatively simple structure and lower manufacturing costs.
2. Easy maintenance: Brushed motors are relatively easy to maintain because their mechanical parts are more easily accessible.
3. High starting torque: Brushed motors have a large torque when starting, making them suitable for situations that require a large starting force.

Common faults of brushed motors:
1. Brush wear: The brushes in brushed motors will gradually wear out with use and need to be replaced regularly.
2. Commutator erosion: The commutator in brushed motors may experience erosion, affecting the normal operation of the motor.
