To start off let me clarify my attempt to explain the function of brushes in an electric motor.
An electric motor works because of alternating magnetic fields between the stator meaning the interaction of the coils that form the outer part of the electric motor and the coils in the inner part of an electric motor.
The brushes are used to contact the commutator which provides charge to the coils in the rotor.
The Rotor is a set of magnetic coils in the inner part of an electric motor the alternating fields cause the rotor to rotate which provides the driving force needed to power whatever is being used, be it an electric drill, a hair dryer or a car.
Now isn’t that just as clear as mud?
Hope to see you on the road.
