28mm NEMA 11 Low Noise DC Brush Gear Motor 24V 167 Rpm 0.12A
Construction of Brushed DC motor
It typically consists of a pair of permanent magnets named as the stator and a motor coil named as the rotor connected to a commutator. In this motor, armature winding is on rotar and permanent magnets are always on the stator.
Conductors always locates on the turning part. practically, these conductors get power from direct current power source. It uses metallic brushes (which rotate along with the rotor) to transfer the current to the coil. Though these motors are quite efficient but they require periodic maintenance of brushes.
