Well ive spent the last two nights trying to figure out what i need for current limiting resistors for our router build and im throwing in the towl and asking for help
We are building a jgro style router with a 97" long (in Y) table and using nema 34 framed motors
spec sheet's here http://www.kelinginc.net/KL34H280-45-8A.pdf
The powersupply we are going to go with is giving us 36v DC with more than enough avaiable amps (borrowed it from an old 3axis cnc with massive ac servo's and built a rectifier for it)
Now from my math, i think i need 3.28ohm 330watt resistors or if split them up and run two resistors per motor (wired unipoler) i can go with 6.5ohm 165watt resistors
Is this correct? or am i wrong?
And either way, what do i need and where can i buy them? Digikey is showing $80 for resistors large enough by math, im hoping im wrong
Thanks
