## Questions & Answers

**Q: Is there an adapter available to fit the 11mm input shaft of a 20:1 speed reducer nmrv030?**
A: They are researching it here, where the motor is sold. Wish I had an answer, but at least I'm not THAT guy.

**Q: How many RPMs will the motor run before the torque drops in half?**
A: The torque is highest at a slow 10 RPM. The torque drops linearly at the RPM increase. It starts to skip pulses because of low torque at about 200 RPM. I had to add a 100 tooth to 36 tooth xml timing pulleys to increase the torque.

**Q: Where can I get a gear that works with this 10mm shaft? Most of those I've seen are in standard, not metric units.**
A: I've had luck finding pulleys on EBay. I'm not sure about gears but it would be worth a shot if you haven't already looked. Also you could buy something to fit on a 3/8in shaft and drill it out to 10mm.

**Q: What is the maximum power output in Watts? I’m sure it’s higher than the 3W they have listed.**
A: Hello, 

The power is calculated as:
P = V *I* # of coils active, or equivalently 
P = I^2*R* # of coils active
For instance, if only one coil is active,
P=4.2^2*0.9*1 = 15.87 watts
If two coils are active, such as when the motor is holding a position, then the power doubles, which comes down to 31.75 watts. 

Hope this helps,

Hector
