A brushed DC motor is a DC motor, assembling main magnetic pole and brush on the stator and assembling the winding coil and commutator assembled on the rotor. The electric energy from the dc power supply enters the armature winding through the brush and commutator, generating the armature current. The magnetic field generated by the armature current interacts with the main magnetic field to generate the electromagnetic torque, making the motor rotate to drive the load.
