What is DC Brushed Motors
DC brush motor is a rotating motor with brush device to convert DC electric energy into mechanical energy (DC motor) or mechanical energy into DC electric energy (DC generator). Different from DC brushless motor, brush device is used to introduce or lead in DC voltage and DC current. DC brush motor is the basis of all motors. It has the characteristics of fast start, timely braking, smooth speed regulation in a large range, relatively simple control circuit and so on.

Composition classification of DC Brushed Motors
The components of the basic structure of DC brush motor include stator, rotor, brush and commutator. The interaction of stator and rotor magnetic fields drives the motor to rotate. The type of Brushless DC motor is divided according to the generation mode of magnetic field in motor stator or shell. Depending on the type of Brushless DC motor, the stator magnetic field can be generated by permanent magnets or windings in the stator. In the latter case, the stator winding and rotor winding can be connected in parallel, serial or mixed mode. These three kinds of Brushless DC motors are called parallel motor, series motor and compound motor respectively.
Principle of DC Brushed Motors
The stator generates a static magnetic field. This static magnetic field surrounds the armature (or rotor). The external power supply excites the armature magnetic field. There are also two arc-shaped copper sheets on the motor shaft of DC brush motor, which are called commutator. When the motor rotates, the carbon brush slides on the commutator. In this way, a rotating magnetic field attracted by the static magnetic field of the stator can be generated. The current in the armature and stator windings is supplied by batteries or other DC power sources (permanent magnet DC brushless motor has no stator winding). The battery (or DC power supply) provides a constant DC voltage. The voltage amplitude determines the speed of the motor, so the battery or DC power supply is a linear excitation source. The most effective way to change the speed of DC brushless motor is to use pulse width modulation (PWM) technology. PWM technology switches constant voltage source with fixed frequency. Changing the pulse width of PWM signal can adjust the speed of motor. The ratio between high and low levels of pulse is called the duty cycle of PWM signal. The amplitude of DC battery level is equal to the average amplitude of PWM signal
