## 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.
