what does brushless mean in power tools - EXTOL

Brushless refers to a type of motor used in power tools. It is also called a brushless DC motor. Compared to the traditional brushed motor,  you may know little about brushless power tools.

This article covers the concepts and applications of brushless motors, as well as comparisons with brushed motors, to help you have a deeper understanding of these two types of power tools and help you make a wise purchasing decision. 

Brushless Technology Explained

Brushless motors, as their name implies, operate without the brushes and commutators found in traditional motors. These brushes are part of a system that delivers power to the motor’s spinning part, or armature. In a brushless motor, an electronic controller replaces the function of the brushes, providing energy to the motor windings.

In this design, the permanent magnets are attached to the rotor (the spinning part), and the electromagnets are stationary within the stator. The electronic controller rapidly switches the magnetic field in the stator to attract and repel the permanent magnets on the rotor, causing it to turn.

The elimination of brushes means there’s no physical contact that would cause friction and wear. This results in a motor that’s more responsive and can adjust its speed and power to match the task without the limitations of a brush-commutator system.

Brushless vs Brushed Motors 

So, what are the differences between brushed and brushless motors? Here is a summary. 

Pros and Cons of Brushless Motors 

As a new technology, a brushless motor has both advantages and disadvantages.

Pros of Brushless Motors
