Hi folks, I need to drive eight brushless DC motors (on board a robot) and deliver a lot of power to them (100-200W each). I also need to decide the wiring topology (e.g. some sort of bus would be nice from a cable run point of view, while a star seems better for other reasons). Can you recommend a good reference text on motor drives or power electronics or something like that? I feel like I understand the basic principles but not the potential "gotchas" involved in cramming this much current through cables. thanks --Jim -- jmorash@mit.edu Research Engineer - MIT AUV Lab - http://auvlab.mit.edu -- http://www.piclist.com#nomail Going offline?
