The brushed DC motor is a common type of motor that is widely used in various devices and systems. Its working principle is based on the interaction between the magnetic field generated by the DC current passing through the motor's coils and the permanent magnets.
brushed DC motor is a DC motor. The stator of a brushed motor is equipped with fixed main magnetic poles and brushes, and the rotor is equipped with armature windings and commutators. The electric energy of the DC power supply enters the armature winding through the brushes and commutator, generating armature current. The magnetic field generated by the armature current interacts with the main magnetic field to generate electromagnetic torque, causing the motor to rotate and drive the load. Due to the existence of brushes and commutators, brushed motors have complex structures, poor reliability, many faults, large maintenance workload, short life, and commutation sparks are prone to electromagnetic interference.
