DC Brushed Motors rely upon a mechanical system in which brush orientation on the stator or in relationship to the rotor's bar segments determines current flow. Within that process, the commutator, which reverses current direction to keep the motor turning, is especially important. The DC brushed motor's wound armature is attached to the center with a permanent magnet bonded to a steel ring around the rotor. As brushes contact the commutator, the current then moves through coils in the armature. The mechanical system thus manages the current flow and maintenance.
DC Brushed Motors generally provide greater power than AC motors and deliver flat torque over a wider speed range. DC brushed motors offer simple and easy-to-use speed control with a low up-front cost. This has allowed such motors to remain important in a variety of contexts, from steel mills to paper-making machines and automotive accessories.
