Need Information About Used Steppers

[Mr.Chips]

I Have purchased a batch of 5 steppers at EBAY, four are bipolar and one unipolar. I plan to use the bipolar ones in my first machine.
Since they are used steppers I don't have a spec sheet and not all the information I think I need is on the motors.
I have measured the resistance of the two coils and identified those. I don't know which wire is 1 or 2 or 3 or 4. I understand I must know this before connecting.
Also don't know the volts and step angle on some. If someone could help me out I would appreciate it.
I have it in a spread sheet and will try to attach it or display it in a picture format so you can see the information.

Regards,
Hager

Save as jpg instead of bitmap, the file size will be much smaller.

Thanks,
The image file was too big.

Retiredhh,

I can tell you about the Vexta wire color codes as they are what I have.

Black--------|A+
|
|
Yellow-------|Center Tap
|
|
Green--------|A-


Red----------|B+
|
|
White--------|Center Tap
|
|
Blue---------|B-

I hooked the power up to the White and Yellow. The phases were Black, Green, Red and Blue in that order. Of course that was for my unipolar driver. I guess you eliminate the two center taps for bipolar use.

PS The ascii graphics didn't come out very well. I do have the origional spec sheet. It doesn't give much more valuable info than that though. If you want I can scan it for you. Let me know.

[Mr.Chips]

Thanks for the information Chris. Don't think I need any more information on this stepper.
I baught all 5 in one sale on EBAY on one bid, plan to use the Bipolar steppers.

Hello,

New to the forum, hope I'm doing this right.

I have 4 motors: vextra 2-phase DC 16V 0.53A 1.8Degree stepper...6 wires coming out of the thing.

What kind of torque/speed can I expect out of these, and what kind of drive would I need to drive all four of these motors simultaneously?

Thanks in advance,

Kevn Lambson
