Would like some advice from the experts please.
I have 2 options and i have read lots about stepper motors and matching power suppy etc and think i have got this right.
This is for a small/med size router im building.
I have 2 leadshine drivers and 1 gecko both rated at 80vdc max.

So at the moment i have an unregulated power supply with a 800va 50vac tap torriadal transformer which gives me about 71-75vdc output.
Using this i can buy nema 24 430oz in motors 2.8a with 6.8mh inductance.
Buy my calc. Max volts for these motors is 83.5v so my transformer should be good for 3 motors for volts and amps.

Option 2 is nema 24 425oz in 5amp 2.3v motors with 2mh inductance.
But this will mean i have to buy a new transformer which i would rather not.
If i do i can get a 500va 30vac tap transformer which will give me 42vdc and enough amps for 3 motors i think?

So after a long thread start and if my calc are correct because i have enough volts in my existing transformer are the high inductance motors going to be ok or would i be better getting the low induc motors and a new transformer?
I only want to buy once.

Thanks.
