According to DeWalt’s support forum, “A brushed motor uses brushes and a commutator to supply electricity to the magnetic coils of the armature. This can create friction, heat, and loss of energy at the point of contact.”


In contrast, brushless motors eliminate the need for brushes and the commutator, minimizing friction commonly found in traditional brushed motors. This advanced design causes a cooler, more efficient motor, reducing the wear and tear you see on brushed motors.


While brushed motors have been the most popular design for tools and power equipment by providing professionals with fast-paced and efficient work performance, the fundamental difference between brushed and brushless motors lies in their operational mechanisms.

Brushed Motor Key Points

  • Relies on mechanical action, with permanent magnets in the stator and electromagnets in the rotor.

  • Carbon brushes maintain contact with the commutator, transferring electrical voltage to create an electromagnetic field in the rotor.

  • Continuous polarity switching through the commutator generates the motor's spinning motion.

Joerg Zellerhoff, group product manager at DeWalt, said, "Increased runtime is one of the biggest benefits of brushless motors in cordless tools. DEWALT coupled brushless motors with high-capacity batteries to deliver EXTREME RUNTIME to our users," Zellerhoff also said "The push to higher voltage like 12V to 14.4V and 18V gave cordless tools more power in the late 90s. Lithium-ion battery technology has provided a lightweight battery option, with no memory effect, for cordless tools during the last six years. Brushless motors are now improving the runtime of cordless tools compared to standard brushed motors and make them desirable to contractors."

Notable Advantages of Brushless Motors

  • Decreased motor maintenance, as there are no brushes to replace.

  • Extended motor lifespan due to operating at a cooler temperature.

  • Increased power.

  • Fewer battery changes or charging as brushless motors extend battery runtime.
