brushless
Lacks sweeping filaments
Brushless describes motors or devices that operate without carbon brushes—the physical contacts that traditionally transfer electrical current to rotating parts.
Brushless motors use electronic controllers instead, making them more efficient, quieter, and longer-lasting: a brushless drill, brushless DC motor.
The term appears most often in power tools and computer fans.
