What is dc brushed motor

Dec 26, 2017

Brush DC motor is a DC motor, brush motor has a fixed stator mounted on the main pole and brush, rotor mounted armature windings and commutators.

DC power through the brush and commutator into the armature winding power, resulting in armature current, armature current generated magnetic field interaction with the main magnetic field to produce electromagnetic torque, so that the motor rotating load. Due to the existence of brushes and commutators, brushed motor has complex structure, poor reliability, many faults, large maintenance workload, short service life and easy to produce electromagnetic interference due to commutation sparks.
