Related to your ESC-
a. Why you need heatsink at all? - So I can use it for almost any application, and stress it all I want, without it complaining. b. How much power you need to dissipate? -Easily 2000watts peak handling c. What temperature range of the ESC and FET's you would like to have?- Does this mean ambient temp? Or the operating temp? I would like to keep the FET's under 30F above ambient. "How much power you think you dumping on ESC?"-Is this power output? Or heat output? Related to future ESC- a. What temperature range of the ESC and FET's you would like to have? (copy of "c")-Again, less than 30F above ambient b. How long you would like your ESC to work continuous at 25%/50%/75%/100% load?- 25% Continuous, 50% Continuous, 75% 5 mins, 100% 1 min "What kind of Amp ratings you would like to have from ESC and why?"- Psshh, 200 amps? I don't really want to draw any more than 100 amps, but the FET's will not be stressed, thus no need for heavy cooling. |

HEHE, what can I say, the questions aren't that understandable! :whistle:

MambaMax FET's driver has troubles driving my new FET board, so I will make new board with built-in drivers...
I will check my math again as well. Brains side and FET's side |
Wow, that looks better than some 'proper' escs do. Do my eyes deceive me, or are there only 6 giant fets on that?...
|
It looks very nice. Those FETs are really tough. I hope it works out. What are the specs on the FETs? What will the specs be after you are done?

Nice work, you can tell its designed for high currents- the copper traces are massive compared to the gaps between them; its usally the other way around whenever I get bored and di-sect some broken electronic device before I throw it in the bin.... Here's hoping this one works better than the last one, Im sure it will though.

While waiting on parts from Digikey, decided to play with Schulze.
Prototype works alright, no problems so far. I'll try to dress it up and check on the truck. |
Cool work Artur!
why not use a mamba 25 as a controller-board? |

$80.00 for 25A looks expensive for me when you can get 100A for $135.00 and I can re-use parts from MambaMax, not sure about mamba 25. But I don't see any problems with using Mamba 25 brains with my power boards. Once I make it to work with MambaMax it would work with all Castle family, I hope :) |
great!, good to hear.
What's the current limit on these proto-types? |
Artur,
On the Schulze controller, I see the small SMT resistors next to were the MOSFET goes. If I wanted to make extra powerboars, would thee work with the same resistance or would I have to use different resistance for everything to work ok? The reason I'm asking is because I see a few controllers that stack powerboards to up the AMP rating. |
