Product Q&A
Submit a New Question-
- The power tool comes with a motor that uses electronics to detect position and transfer electrical current into the stator, which is why brushes are not needed.
- Brushless motors use electronic controllers to switch the current direction, which makes them more efficient and reliable than their brushed counterparts.
-
- Brushless motors have fewer moving parts, which reduces the wear and tear and increases their lifespan.
- More efficient due to the absence of brushes that often tend to wear out.
- Run cooler since they create less internal friction and heat.
- Are often lighter and more compact than brushed motors.
- Can more readily allow higher speed or increased torque than a brushed motor, which can result in an improved user experience.
