One of my favorite types of motors is the brushless motor. A brushless motor is a type of DC motor that does not use brushes and commutators to convert current into a coil, but instead uses an electronic controller that senses the position of the rotor and adjusts accordingly. Controls the current. Brushless motors have many advantages over brushed motors, such as higher efficiency, higher power-to-weight ratio, lower noise, longer life, and better controllability.
