What is the Difference Between Brushed Motors vs Brushless Motors?

The goal of this article is to inform people on the general idea of the difference between brushed motors and brushless motors. If you are looking for more details on the topic, then this article is not for you. To keep things simple, the motors that we are discussing in this article are going to be DC motors. As far as pros and cons go, each has their own fair share of pros and cons.

Brushed Motors

Brushed motors have a simple design when compared to brushless motors. It contains brushes in its design that can be replaced. Brushed motors are great for dealing with rough environments. Due to its simplicity, they are easily replaced should problems ever occur. Fewer circuitry and additional components are not needed for it to operate due to most of these motors boasting a fixed speed design.

Because brushed motors are simple in design, they are also less expensive compared to brushless motors. In terms of overall lifespan, it will be lower compared to brushless motors due to the fact that its brushes and commutators will wear out over time. Again, brushes can be replaced.

Brushless Motors

Brushless motors are designed in a way where its rotor is surrounded by several permanent magnets. For those of you who don't know, the rotor is the thing in the middle that spins which you connect or attach items to that you want to get spinning. What this means is the rotor requires no power (no connections, etc.)

To determine where the rotor's position is, an extra sensor(s) such as hall effects are required along with extra circuitry.

Brushless motors tend to be more efficient and longer lasting due to the fact that they don't have brushes to wear out or to replace which makes maintenance easy.


Brushed motors are simpler in design when compared to brushless motors. They last longer and are usually fixed in speed. Brushless motors are more complex but its position can be determined through the use of extra sensors. Which one to use? That ultimately depends on your application.
