Does this mean I have grossly underestimated the total current necessary?
the mosfets (520) become hot.
Sorry, I am inexperienced and don't know exactly what parameter to look for in this data sheet http://www.datasheetcatalog.org/datasheet/fairchild/IRF520.pdf. Would you please advise whether it is a "logic level" mosfet? The motors were salvaged from office equipment. I will try to locate a data sheet.
Drain to Source On Resistance (Note 2) rDS(ON) I D = 5.6A, VGS = 10V (Figure 8, 9) - 0.25 0.27 ?
Drain to Source On Resistance (Note 2) rDS(ON) I D = 30A, VGS = 5V, Figure 9 - - 0.047 ?
Thanks for the quick response. That must be the problem. The motor is drawing .17 amps at max efficiency and 1.06, stall so an 8 amp supply would seem more than sufficient to run three, plus the servos, and steppers? Do you think a tip31http://www.datasheetcatalog.org/datasheet/boca/TIP32C.pdf would be a better choice?
