Help, what are these steppers?

[ljogwin]

I have 7 stepper motors that are 2.25" diameter and 3.25 inch long. They are 1/4 inch shaft and marked: SIGMA INSTRUMENTS, INC.
MODEL
20-2235D200-E3.7

These steppers have 6 wires; org/blk/white white/red orange red black yellow. The body color is green. Nice heavy steppers that I would like to put on a xy table. Any help appreciated. Is there any way I can determine current / voltage to use on these?

Also have a Step-Syn by Sanyo Denki 103G718-0243 5ohm, 24vdc 1.8deg .8a I am trying to find info on. Does the 24vdc mean the supply is 24vdc?

Any help will be appreciated.

Thanks
Ogg
