"Brushless" refers to a type of electric motor that operates without brushes, which are components that traditionally transfer electricity to the motor's rotating part. In brushless motors, magnets and electronic controllers replace brushes, leading to increased efficiency, reduced maintenance, and longer lifespan. This technology is commonly used in various applications, including drones, electric vehicles, and power tools. The absence of brushes in these motors minimizes friction and heat generation, allowing for smoother operation and better performance. Brushless motors are often more compact and lightweight compared to their brushed counterparts, making them ideal for applications where space and weight are critical factors.
