Do brushed electric drills and brushless electric drills work on the same principle?

The main difference between a cordless brush drill and a cordless brushless drill is the structure and working principle of the motor.

There are carbon brushes and commutators inside the motor of a brush electric drill. When the motor rotates, friction will occur between the carbon brushes and the commutator, resulting in sparks and noise. For this reason, a picture is specially provided to help you understand more intuitively. different. There are no carbon brushes and commutators inside the brushless electric drill's motor. Instead, an electronic commutator is used to control the rotation of the motor. Therefore, the brushless electric drill has higher efficiency, longer life, and lower noise.

In addition, brushless electric drills are usually lighter and more compact than brushed electric drills because they do not require mechanical components such as carbon brushes and commutators. Take Westul's CDD-30N-B and CDD45N-BL as examples. It is obvious that The latter is seen to be more compact and beautiful. Brushless drills also have higher speeds and more torque, making them better suited for jobs that require high power and efficiency.

In general, brushless drills are more advanced, more efficient, and quieter than brushed drills, but they are also more expensive.
