Making an esc better?

[suicideneil]

Would it be possible two wire to esc' in parallel to a motor?.... or is that just crazy talk. I was thinking connect the battery to both esc', then both esc' to a single BL motor. I'm guessing it would result in a puff of smoke & flames, but it would be interesting to try with a couple of those cheapo Bl systems you see on ebay- or try modding them both together to work as a more powerful system = experiment on them rather than a good MM...... [/crazy idea]

Griffin,

What is the result of running two output stages in parallel? Would I get roughly double the voltage and current tolerances? Perhaps I should send you two MMs.

Brian correct I was also thinking about replacing output stage with something more heavy-duty, like Direct-FET or D2-Pak 7...
Custom PCB and hopefully MM can drive them, otherwise custom driver as well, which can be done with ir2101/ir2102 or simular.

Double the current, same voltage...

Thats the rating...no where in hell will any brushed motor really pull that without turning into a metal glob though. I believe the Novak GTX supports like 760 amps (or so they say...).

lol, pretty much redesigning everything except the brains. If the power board is running at higher voltage, won't the feedback pulses be too high for the controller? Or do you somehow clamp them down?

OK, this is getting WAY over my head. All I want (and I don't think I'm asking much) is a controller that will handle up to 6S, though I can live with 5S, and a decent current handling capability that doesn't suffer from heat problems and is smooth at low throttle.

lol, aangel dont worry I think brian and arthur are talking over almost everyones heads.

AAngel, that would be a Quark, besides the heat problem, though that can be cured with the RCM heatsink. It handles 5S (says 6S, but it doesn't really like 6S) and is very smooth.

I agree. Aside from the heat and no solid 6s issues, it truly is a winner IMO. I really think that the heat issue has to do with how it is programmed. It is just so much smoother than the MM even though it uses the same FETs and number of them. I think they sacrifice a little efficiency for a better running ESC, but that's just my theory...

lol, well given the title of the thread, it was bound to get a little technical. :)

Really, all the good ESC manufacturers should get together and make something that really works well. Castle's programmability and versatility (being able to run brushed/brushless), Quark's smoothness and zero cogging, and MGM's high voltage capability (10s/36 cells!!). Throw in a switching BEC built-in and they could market it as an "All Stars" ESC. And while they're at it, add a port to daisy-chain optional power boards for added current capability. :)

so long as schultze was not involved (loose connectors) I'd buy it

That would really be awesome, and then all the companies can just split the earnings between each other.

[BrianG]

I specifically left Schulze out of the list. What would be the point of making the ultimate ESC that suddenly bursts into flames? :)

[gixxer]

lmao, but yet so true. Right now I would just be happy with 6s and the ease of the MM programming. Anything more then that is just a bonus for me.
