## Description

This type is miniature Worm Gear DC Motor, which can change shaft rotation direction while the wiring positive andnegative be changed . It is also have addition two characteristics: 1. With self-locking, the output shaft can not rotation when switch off, that is self-locking.2. Gearbox output shaft and motor shaft are come to be a rectangle, it is widely used in various of occasions that require special install size.Apply to robot, display cabinets, electric door, electric curtains, electric racks, barbecue machine, barbecue pits, electric toys,hands-on DIY, etc. And if you need other voltage and rpm, pls contact us, there are many other models of this motor in store.The standard torque of the motor is 10kg.cm. If the belt wheel is used for transmission, the belt wheel has a radius of 1cm, and the output tension of the belt is 10kg. If the belt radius is 2cm, the output tension of the belt is 5kg, and so on.

Review: Great buy
Review: I've purchased a few of these gear motors and will continue to do so, they are decent. I bought 3 of the motor speed controllers also, and one arrived dead and the other 2 went up in smoke after just a few minutes of use. I didn't do a post mortem on the dead controllers, but it seems from the extreme heat that the 7805 regulator is what burned up, or maybe the control chip itself shorted and then the regulator went next. With the damaged controllers, the motor still runs and can reverse, but only at full speed. The biggest thing I don't like about these controllers is that the control chip itself is not a standard, servicable part. The little 8-dip IC is actually an 8-bit microcontroller with custom programming, so if (when) it dies, you can't just swap in another. Competitors' products use an op-amp or 555 instead, which are easily replaced parts. Maybe there is some benefit to this custom chip, but it seems like overkill and it makes the thing end-user non-repairable. Sure, $13 is not a lot of money to replace the whole board, but a $0.70 IC is still a lot cheaper.

## Questions & Answers

**Q: Will it work with ac adapter 12v 3.0 a?**
A: This is a DC motor. So the input voltage must be DC voltage. AC volatge can not work. This motor needs DC 12V volatge to work normally.

**Q: Is this motor strong enough for an electric wheelchair?**
A: strong enough yes but i don't think it would last very long. plus it is very slow, 12 revolutions per minute . i would want my wheelchair to be a lot faster than that.

**Q: Will these work for combat robot**
A: I'm not sure. It has lots of torque. At 16rpm, I'm not sure if it is fast enough for the combat you have in mind. Also, I have not used it enough to determine how reliable or durable it is. The same manufacturer has 32rpm and higher versions. I would buy one of each and test them. I'm pleased with it so far. I've purchased 4 of them.

**Q: el motor reductor de 12 volt y 80 rpm, cual es el torque real?**
A: The torque of 12V 80rpm is about 15kg.cm. Torque means that when the radius of the contact area between the motor shaft and the load is 1cm, the maximum weight that the motor can load is 15kg. When the radius of the contact area is 2cm, the maximum weight that the motor can load is 7.5kg. And so on.
