Stepper short list on VM32L Weiss mill advice - low inductance

[JAZZCNC]

also would the 50Vdc make a massive difference compared to a 2 phase with 70-80Vdc driver

Yes it will mostly make a difference to the speed but not by a massive amount, roughly 300rpm, these will give 1200rpm and the others will be 1500rpm.
They are not exactly like a standard stepper system and the encoders come into play so can restrict the speeds.

If I wanted to have excess power and plenty of speed along with AC drives then I'd fit these and sacrifice the smoothness 3phase offers as they are 2 phase.
Nothing gets close to these for power in the Nema 24 range. Again I've fitted plenty.

The wiring is easy enough just shout if you need help.

Not fair!!!!!
Just looked at buying 2 and it wants £90 shipping?????

Jazz. I was wondering if you could clear something up for me. I was looking at these motors and drives you recommended and on the pics it says 20-70v ac. Is that correct or is it 220 ac straight input.

Yes John it's 20-70Vac or 30-100Vdc. The AC option Just saves messing around with Bridge and Caps but still need a transformer to get from 230Vac to 20-70Vac.

Some of the Larger Nema 34's drives like these work direct from 230Vac mains. These are great for larger machines because they spin fast and have loads of torque.
