Brushed DC motors are electric motors that use direct current (DC) to generate motion. They consist of a rotor, stator, and brushes that make contact with a commutator. The brushes supply electrical current to the rotor, creating a magnetic field that causes it to spin. This design allows for simple control of speed and direction. These motors are commonly used in various applications, including toys, power tools, and automotive systems. Their straightforward construction makes them easy to manufacture and maintain, although they may require more frequent maintenance due to brush wear over time.
