Re: vexta steppers

Kenneth,

They are the forerunner the the H Series that Mariss mentioned, they
have regular alnico magnets. Don't have that exact model listed in
any of our old catalogues, so expect it was a special for one
particular customer. The part nos: 103-746-1 and 103-746-2 show it
as a 6 lead unipolar 3 stack (4" long) NEMA23 motor. The specs say
the have holding torques of 10.8kg.cm (about 150 oz.in). They should
work fine with the G210/210 but I doubt you will get the same
linearity as the H Series.

That's my 2 Euro's worth ;-)
