do you have any 2 that are the same? |
No, I don't. So far I've retrieved 3 of the steppers from 3 of the printers...I have a large, medium, and small.
The largest is a 100 oz-in stepper, a Minibea Astrosyn 23LM-C701-01. 5.2V/phase, 1.4A/phase.
The medium is unknown so far (still google searching), a Minibea Astrosyn 23LM-S047-G1. 4.2V/phase, 1.2A/phase. Considering the almost insignificant difference between it and the first one, I expect that they're pretty close in capacity. It's 20% less voltage...maybe 80 oz-in? It's a guess, but not an entirely unreasonable one, assuming that it's a linear function.
Both of these are 1.8 deg per step, so 200 steps per revolution.
The smallest is by the same company, but has an IBM part number...thankfully it also has another number, 23LQ-C202-G2V. It has no voltage or amperage specs on it, as well as having no deg/step data. IBM didn't like their motors to be well documented, apparently. By using that number, I was able to find out it has 2/3 the torque of the 100 oz-in one, so it's around 66 oz-in, and get all the voltage and amperage specs. It's around here, somewhere.
I believe you should have 2 of the same stepper for your X and Y axis. |
Well, I've still got 1 or 2 more printers, so there's still a chance! :-)
Do you have a picture of the motors? Im just curious to see them. |
I'll see what I can do...I've got a digital camera, but incandescent light isn't the best stuff for photos. It's an older model...doesn't have white balance.
...
Well, they seemed to come out acceptably. Now, to figure out how to post them. Hopefully it'll show, below.
If those steppers came out of regular bubble jet prints I dont think they are going to be powerful enough to run your machine. |
Big ancient LASER printers...the biggest one came from a gigantic HP laserjet III commercial grade printer. Sadly, the other printers, while heavy duty, are apparently designed for home use and have lighter duty components. Not much lighter...but lighter nonetheless.
