ok, so it might be a mistake, but i did it anyway, i ordered my electronics for to build the drivers, l297's and l298's and some diodes... and then just now i ordered my motors.. i got 3 nema 23 500oz-in 4 wire bipolars for $175... so how'd i do??
the way i figure it, ill spend the weekend building the driver boards, then early next week the motors will get here from california and i can test both them and the drivers... pluss then i can see what the no load speed of the motors is, and that will give me some kind of an idea as to what i need as for the rest of the drive train...
I did have this thought... what if i mount one of the motors onto something solid, and then mount a large set of fan blades.. i know theres not really a way to measure the amount of load, but it would allow me to see how much the rpm's fall off and or if it starts cogging, and give me some idea as to what kind of ramp up to play with.... Ideas? suggestions??
