Get high-quality N20 DC motors with custom encoders from our factory. Find worm gearbox products for all your industrial needs. Shop now for efficient solutions.
This is a DC worm gear motor with N20 encoder.It is also available without encoder.The outer diameter of the N20 motor is 12mm*10mm, the motor length is 15mm, and the length of the gearbox is 18mm (the gearbox can also hold an N10 motor or an N30 motor).The motor consists of a metal brushed DC motor with a precision metal reducer. The worm gear has small size and large gear ratio.The DC motor technology is relatively mature, inexpensive and simple to drive and control. With a gear box, the torque is greatly increased, the speed is reduced, and it is easy to control!The following worm gearbox gear ratios are available.1:21 1:42 1:118 1:236 1:302 1:399 1:515 1:603 1:798 1:1016

When changing the drive voltage, or changing the motor winding parameters, the motor will have different characteristics, this curve is for reference.N20 DC motor can also be matched with GB12 gearbox, 1024GB gearbox， As shown in the figure： 1.N20 DC motor + GB12 gearboxLead time for samples: Standard motors in stock: within 3 daysStandard motors not in stock: within 15 daysCustomized products: About 25~30 days (based on complexity of customization)Lead time for building a new mold: generally about 45 daysLead time for mass production: based on order quantityPackaging:Samples are packed in foam sponge with a paper box, shipped by expressMass production, motors are packed in corrugated cartons with transparent film outside. (shipping by air)If shipped by sea, product will be packed on palletsOn samples and air shipping, we use Fedex/TNT/UPS/DHL. (5~12 days for express service) For sea shipping, we use our shipping agent, and ship from Shanghai port. (45~70 days for sea shipping)1.Are you a manufacturer?Yes, we are a manufacture, and we produces mainly stepper motors.2.Where is your factory location? Can we visit your factory?Our factory is located in Changzhou, Jiangsu. Yes, you are very welcome to visit us.3.Can you provide free samples?No, we don’t provide free samples. Customers won’t treat free samples fairly.4.Who pays for shipping cost? Can I use my shipping account?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 motorsThe 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. 1. Fast speed2. small size3. High efficiency (compared with stepper motor)4. Universal use5. Easy to connect and easy to use6. InexpensiveElectric DC worm gear motors are mainly used in various applications such as windows, household appliances, model cars, model robots, model ships, industrial applications, DIY engines, miniature winches, remote control curtains, miniature door openers, barbecue grills, ovens, garbage disposals, coffee machines, printing presses, etc.2.N20 DC motor + 1024GB gearbox
