At Stanley Black & Decker we take great pride in the quality of all of our consumer products, and with our professional tool division of DEWALT launching brushless power tools to lead the way, B&D has now begun the use of brushless technology with the LST540 String Trimmer and you can expect more as we move into the future.

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.  

With a brushless motor, however, we do away with the commutator and brushes, and thus, the friction generated on a more common motor. This design allows for a more efficient, cooler motor and less wear and tear.

So the more noticeable benefits of the brushless design will be

• Less maintenance (no brushes that need to be replaced)
• Longer motor life (due to cooler operation)
• More Power
• Longer Runtime from the same battery
