Need help identifying a couple servo motors

[praetor]

Can anyone help me with the specs of this type of DC servo motor (atleast, I think it's a servo motor)

the numbers on the labels are as follows:

NMB UNIVERSAL MAGNETICS, INC.
AN NMB COMPANY
10211-301-000
ME21026017 8540

I tried googling the numbers for data sheet search but came up with bupkiss...can anyone help?

The brushes indicate a DC servo motor fitted with an encoder on the rear.
No data on it though.

Yeah, I knew they could be servo (yeah, I forgot to mention the encoders, also) but I have really never messed around with servos but have seen many bench top machines with similar servos, which had me thinking of using these on a lathe, but there in lies the problem, I haven't the specs to work with...but again, Al. thanks for confirming.

Looks like the servomotors out of a plotter that once had! Will look around and see if I have any specs.

If it's like the servomotors I've dealt with ,the only significant part of the part number is probably the 10211. The -301-000 would be a tie to the customer's specs (i.e. modification of the base part like the custom shaft etc.) and would be just a sequential number (i.e. the 301st variation of the basic part), the ME21026017 would be the customer's internal part number and the 8540 would be a datecode (40th week of 1985).

Not that that helps, because the -301-000 might also specify a custom winding.

For the encoder, just pull off the endcap and look at it. It will be a standard part (likely from US Digital)

Edit: Here's a post by Al The Man on determining the characteristics of a DC/servomotor. /edit

Bubba, it sounds like you had the same plotter that this guy had. I hope you can help praetor.

The plotter company I worked for (Zeta Graphics, formerly Bruning Computer Graphics, formerly Nicolet Zeta, formerly Zeta Research) tended to use Clifton servomotors.

I want to thank you guys for helping me with these motors. Bubba they are from a plotter I don't remember the name of the machine, I just grabbed the motors, but any help would be greatly appreciated, again thanks

I have two of those also. came from a calcomp plotter I looked over a year ago and never found anything on them

[Bubba]

I haven't found anything yet, but yes mine are from a calcomp that got hit by lightning about 15 years ago! I thought about using them when I cnc'd my mill drill back about 2002, so hopefully, I can still find the info I had. If not, maybe we can figure it out from some formulas that were sent to me by Mariss!

[kevin swan]

you can have mine if you want them Bubba

[Bubba]

Thanks, but no thanks! I figured looking at them they were way to small for doing my mill/drill and now lay on a bench or shelf some place:})

I have some that are heavy enough, that I could probably direct couple on my lathe and still break things. That is the next project that I am working on.

One of these days, will stop making machines and make "stuff":})

I understand that it may be hard to tell by just looking at the pics, but it seems you all have more experience with motors and their technical aspects than I do, but at best guess does anyone think these can function properly (mostly fast) attached to a homemade lathe and mill that range between the sizes of sherline and X2 mini-lathes and mills? looks very similar to a Levin toolroom lathe and mill only 1x or 2x bigger.
I'd like to attach these motors (which were removed from a large plotter) to my machines
I am going to be working with wood, 1/4" plexi, 1/4 -1/2 alum and Ren board 5008, all within 24" x 24". would the motors possibly be strong enough to do this, on a smaller scale?:

I understand the difference between the size of the machine in the video and the machine(s) I want to attach it to (apples and oranges and what not) but again, can I achieve something similar or close to that of the video (hell, even half the speed or less would be ok) with my motors but on a much smaller scale? (rough esitmated shape...around...4"x4" minimum to possibly 9 inch square, max?
