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.
