My next problem is that I have discovered that the steppers on this
machine are 5 phase. Granted, These are very precise German made
stepper motors but I don't think I will be able to find a low cost
controller to drive them.
If you put any filtering in the way of caps on the supply you are
going to get about 1.41 times the AC voltage...
I'm in a similar situation: years ago I bid (on ebay) for some servo
motors that turned out to be steppers.
German made, 4 nm. 205 V and pretty good frequency response ... oh
I think if I were to stick with the 5 phase motors I would go the extra yard
and program
a micro with the step sequence so that all that was needed is a step and
direction interface.
I was just reading this web page about how much better 5 phase steppers
are..
