High-Speed DC Gear Motor N20 Gearbox Motor Speed Ratio Can Be Selected
This is a N20 DC motor with a 10*12 gearbox.
The N20 DC motor is also a brushed DC motor and has a no-load speed
of about 15,000 RPM for a single motor.
When the motor is connected to a gear box, it will run slower and
the torque will be higher.
Customers can choose the gear ratio according to their needs. The
gear ratios available for gearboxes are: 2:1, 5:1, 10:1, 15:1,
20:1, 30:1, 36:1 , 50:1, 63:1, 67:1, 89:1, 100:1, 110:1, 120:1,
150:1, 172:1, 210:1, 250:1, 275:1, 298 :1, 380:1, 420:1, 500:1,
600:1, 1000:1.
Gear ratios below 420:1 (including 420:1) have a gearbox length of
9mm.
Gear ratios over 420:1 have a gearbox length of 12 mm.

DC brushed motor is the most commonly used motor in the market.
The DC motor has brushes inside, l positive and negative pins (+
and -).
The speed of a DC motor can be controlled with different gear
ratios or with PWM (Pulse Width Modulation)
With the torque boost of the gearbox, the DC motor can reach higher
torque compared to the original torque of the motor.

Customers pay for shipping cost. We will quote you shipping cost.
If you think you have cheaper/more convenient shipping method, we
can use you shipping account.
5.What’s you MOQ? Can I order one motor?
We don’t have MOQ, and you can order only one piece sample.
But we recommend you to order a little bit more, just in case the
motor is damaged during your testing, and you can have a back-up.
6.We are developing a new project, do you provide customization
service? Can we sign a NDA contract?
We have over 20 years of experience in stepper motor industry.
We have developed many projects, we can provide full set
customization from design drawing to production.
We are confident we can give you few advice/suggestions for your
stepper motor project.
If you are worrying about confidential issues, yes, we can sign a
NDA contract.
7.Do you sell drivers? Do you produce them?
Yes, we do sell drivers. They are only suitable for temporary
sample test, not suitable for mass production.
We do not produce drivers, we only produce stepper motors
