Brushed DC motors use soft graphite brushes and commutator bars to pass current through the motor rotor. However, as these brushes rub against the commutator, they wear out and must be replaced Brushed motors are also larger and may produce more electrical noise than their brushless counterparts.
Brushless DC motors are also called electronically commutated motors. These use a microcontroller to charge electromagnets on the stator, turning the rotor. Brushless motors typically have a high…
