Need Information About Used Steppers
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

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.

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.

what can I expect from these vexta 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
