What is the difference between brushed and brushless Dewalt Tools?

Brushed and brushless Dewalt Tools differ in terms of their motor construction. Brushed tools use a traditional brushed motor, which relies on carbon brushes to deliver electrical current to the motor's commutator, generating the necessary rotational power. In contrast, brushless tools feature an electronically controlled motor without brushes. Instead, they employ permanent magnets on the rotor and electronically switch the current on the stator to promote rotation. This design eliminates the need for brushes, resulting in several advantages. Brushless tools usually offer increased efficiency, longer runtime, and improved overall performance compared to their brushed counterparts. They also tend to be more durable and require less maintenance due to the absence of brushes that wear down over time. Consequently, brushless Dewalt Tools are often favored for professional and heavy-duty applications.
