Known for their superior performance and longevity, these motors have transformed the way professionals and DIY enthusiasts approach various projects. Whether you’re an experienced contractor or a weekend warrior, understanding the workings of DeWalt brushless motors can enhance your tool experience and productivity.
What is a Brushless Motor?
Before delving into the specifics of DeWalt’s brushless motors, it’s essential to understand the definition and functionality of brushless motors in general.
Brushless motors are a type of electric motor that operates without the need for brushes. Traditional DC motors rely on brushes to transfer electrical energy to the rotor, but in brushless designs, this task is handled electronically. This innovation enhances efficiency and reduces wear, thus increasing the motor’s lifespan.
How DeWalt Brushless Motors Operate
The operation of DeWalt brushless motors concerns a few fundamental principles that allow these machines to operate at optimal efficiency:
1. Electronic Commutation
In a traditional brushed motor, electrical current is mechanically switched via brushes and a commutator. However, in the case of DeWalt’s brushless motors, electronic commutation replaces this mechanical process. This setup involves the use of a controller that manages the flow of electricity to the rotor based on the motor’s position.
Key Features of Electronic Commutation Include:
- Enhanced Precision: The absence of brushes allows for exact rotor position tracking.
- Improved Efficiency: Electronic commutation results in less energy loss, allowing for longer run times and more power.
- Reduced Wear and Tear: By eliminating physical brushes and the friction they produce, wear and tear are significantly decreased, prolonging the motor’s lifespan.
2. Rotor and Stator Design
A DeWalt brushless motor consists of both a rotor and a stator, integral components that contribute to its efficiency.
Understanding the rotor and stator:
Rotor: This is the rotating part of the motor, which has permanent magnets embedded within it. With no brushes required, the rotor can spin freely, reducing friction and enabling higher speeds.
Stator: The stator surrounds the rotor and is made up of copper windings that generate a magnetic field when electricity passes through them. The interaction between the magnetic fields of the rotor and the stator is what drives the motor.

What is a brushless motor, and how does it differ from traditional brushed motors?
A brushless motor is an electric motor that uses magnets for its rotor instead of brushes and a commutator like traditional brushed motors. In a brushed motor, physical contact between the brushes and commutator creates friction, leading to energy loss, heat production, and mechanical wear. In contrast, brushless motors rely on electronic sensors to control the movement of the rotor, providing greater efficiency and durability.
The absence of brushes means that brushless motors have a longer lifespan and require less maintenance. They deliver more power while consuming less energy, which is particularly advantageous for power tools like those from DeWalt. This increased efficiency translates to longer run times, making them ideal for demanding applications and environments.
