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.

Lead 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?
