12mm Small DC Gear Motor N20 micro DC brushed motor 3V-12V horizontal gear reducer for shared bicycle smart lock
The motor is made of precious metal brushed DC motor and precision metal reducer. Worm gear size optional solutions, gear reduction ratios are: 1:21 1:42 1:118 1:236 1:302 1:399 1:515 1:603 1:798 1:1030, according to your speed and torque Requires selection of the right motor for the application
N20 motor outer diameter is 12, flat 10, motor length is 15mm (gearbox can also be adapted to N10 N30 050 motor), gear box length is 18mm, the output shaft of the motor has a conventional production shaft diameter of 3mm, D2.5mm, and the length of the output shaft can be adjusted according to Customized according to your installation needs, you can also customize matching spur gears and bevel gears according to your installation needs
Due to its mature technology, low price and simple drive control, DC motors are widely used in cameras, copiers, door locks, optical drives, precision instruments, cameras and other fields.
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.

SPECIAL IMPORTANT NOTES!!!
The components of the basic construction (see follow picture)of a DC brush motor include the stator, rotor, brushes and commutator. The interaction of the stator and rotor magnetic fields drives the motor to rotate.
Therefore, when this type of motor starts and runs, sparks are generated at the brush part, and it cannot be used in special occasions.
Please pay attention when selecting it. In addition, the relative movement of the brush and the commutator is easy to wear, so the life of the DC brush motor with ordinary structure is generally not very long, generally 200~2000 hours, and it is carefully selected in places with strict life requirements.
