STEPPERONLINE High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router

STEPPERONLINE High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router

Q: Is there an adapter available to fit the 11mm input shaft of a 20:1 speed reducer nmrv030?

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?

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.

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.

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
