Does anyone have the specs for this stepper? Such as RPM, Torque etc...

I'm trying to figure out how to gear it for a cnc plasma table.

What other specs do you need besides the ones he posted? Did you look at the pdf he provided a link to?

Do you see RPM, Torque in that pdf? Nopt :nono:


Here is more info for this motor. http://www.automationtechnologiesinc...100-50-4BT.pdf

[ger21]

Probably a similar curve to the 5 amp motor, only the torque will fall off even faster. It's probably only good for maybe 350-400rpm max.
Just a guess, though.

Keep in mind that unless you use the exact same voltage, drives and microstep settings that are used for the chart, you may see very different results.

I'm going to try it with a 3:1 gearhead and see how it works.

The torque is given both in the title and the body of the post. It's 570 oz-in. The only two things missing is the voltage and current "you" intend on using. Once you have that, you can use an online calculator to find out what kind of RPM's you're going to get out of the motor. For instance:

Yes the "holding torque" of 570 oz-in, but I want torque while in motion as in the pdf I posted.

Thanks for the stepper motor calc I'll check it out.

[wendtmk]

The torque is going to change over the range of RPM, depending on how much current and voltage you provide. Without knowing what you are going to provide, all the manufacturer can provide is a single torque curve based on the voltage and current they provide.

That's why they provide holding torque, rather than torque in motion most times.

[modelaratrod]

That makes sense. Looking @ the calc you linked to what's the "mH" on the imput "L" ?

[ger21]

Inductance, which appears to be 6.4mH.
Unless you keep the rpm under 300 or so, I don;t think this motor will work well with a 3:1 reduction.
You'll be spinning it 3x faster, where it has 1/3 the torque.

[modelaratrod]

Maybe this stepper would be better suited? http://www.automationtechnologiesinc...2100-50-8B.pdf
It shows 2.7mH ?

As for the gear reduction the gearhead is 3:1 and it will be turning a 14-1/2 Degree Spur Gear, 24 Pitch, 21 Teeth, .875" Pitch Diameter, 3/8" Bore so I'm not sure what the final reduction will be, is there a calculator for that?

I can also run one these spur gears to find the sweet spot.
teeth pitch dia bore

Yes, but you'll need a drive capable of supplying 5 amps. The motor in this thread was designed to work with lower power drives.

[modelaratrod]

I'm going to be using this drive. STR8 | Stepper Drives | Applied Motion It puts out 2.35 to 8 amps

[ger21]

WHy not use one of these for half the price?

I'm currently using applied motion drivers and have been 110% satisfied with there performance and support. I'm just looking to upgrade for more ipm to cut thinner steel.

[modelaratrod]

There's also the fact that Applied Motion is "Made in the USA"!!! @ least it all was up until a few years ago.

You can use around 80 volts max with that motor 6.4mh squared x32 = 80 volts

[cybot]

3 to 1 will give you 3 time the tork. for my self I am looking at the KL8070D to run the 570oz/in Motors with the 60 volt 20 amp unregulated power supply so if I want to up grade the motors to nema 34 later.
So i don't have to buy new drivers later. You are building a plasma table and the gantry is the only thing that has to have a large motor on it. Nema 34 940oz/in or1200oz/in will run off the KL8070D so I would say it is more upgradeable than the KL5056D or KL8056D
