N20 is a DC gear motor made of precious metal brushed DC motor with
precision metal reducer. The outer dimensions are oblate, outer
diameter 12, flat 10, motor length 15mm, the length of the gearbox
is
18MM, DC motor because of mature technology, low price, simple
drive control and widely used in cameras, copiers, door locks,
optical drives, precision instruments, cameras and other fields.
After supporting the gearbox, the torque is greatly increased, the
speed is reduced, and it is easy to control.
For the gearbox, we have different gearbox for you to choose from,
regular gearbox and worm gearbox. For regular geabox, output shaft
and motor shaft are on the same direction. For worm gearbox, output
shaft is vertical to motor shaft.
Our gearboxes are processed and assembled by imported machine tools
to ensure that the accuracy of each gear is higher than other
manufacturers in the same industry, so the gearbox is stable in
transmission, low in noise, high in efficiency, reliable in
structure, long in life and quality.
There is a encoder attached at the bottom of the motor. It is a
magnetic encoder with hall component. A hall component can test the
position of a magnet ring. Therefore, when a motor rotates a turn,
there will be several signal pulses generated (Pulse number depends
on magnet poles on magnet ring). In this case, the motor will
provide feedback signal, and users can tell how many turns the
motor rotates based on encoder signal.
Our team has more than 10 years of experience in micro-motor
design, development and production, so we can achieve product
development and auxiliary design according to the special needs of
customers!

About DC motor structure
The above diagram shows the basic structure of a DC brushed motor.
This type of DC motor is composed of a stator, rotor, brushes and
commutator. The mutual driving of the stator and rotor magnetic
fields drive the motor to rotate. When they start and run, the
brush part generates sparks and is not suitable for use in special
applications.
The relative movement of brushes and commutator is easy to wear,
and the life time of DC brushed motor with common structure is
generally not very long, usually 200~2000 hours. For customers who
have strict life time requirement for motor, it is recommended to
choose stepper motor.
