A brushless motor is a type of electric motor widely used in radio-controlled (RC) airplanes, drones, and multirotor aircraft. Unlike traditional brushed motors that rely on mechanical carbon brushes to transfer current, brushless motors use electronic commutation—an Electronic Speed Controller (ESC) switches the current to the motor coils, creating a rotating magnetic field that drives the rotor. This design eliminates physical brush contact, resulting in significantly higher power-to-weight ratios and superior efficiency
