Mind me asking why exactly the 282's are the best choice? besides the 25% their rated voltage puts it at my 48V supply and a linear torque curve the 387's have a very similar response but with added beefiness at slower feeds cuz who really needs full torque at rapid speed anyways?
Im an electrician and have some friends at wholesalers keeping their eyes out for cheep 120V:60V or 120V:120V dual coil isolation transformers in the 600-1000VA range but sofar Finding anything above the 24V and less than 120V in a standard transformer is hard.
I would order one from a few electrical/electronics component places but after shipping the prices get ridicules. Who knows when I get to the point where I need good power I will probably just build my own power supply, lots of mosfets out there that can handle >200V and 20A continuous with a crap load of filtering a 60V/20A system off a cheep 120V transformer is possible.
A little off topic, my Vexta 265's are bipoler 2.6A and in Mach3 they are set up as 100ppr and their very accurate even though their only 68ozin. With the 282's in bipoler stepper what should the ppr be? I notice all the rated charts are 2,000-20,000ppr but im nowhere near that...  |
