Thread: 300A VESC in the works, feature suggestions wanted

  1. #41
    On the subject of weight, how heavy is too heavy? I am thinking under 800g each would be good. Although for my bot lighter is obviously better. So I maybe could offer them with several different types/weights of heatsink for different power levels?

    So for example you would have just a flat plate heatsink on to start with and bolt holes for optional bits to go on. Such as a finned heatsink for use with a fan or for light load with convection cooling while being fairly small and lightweight. Then another which is just a big chunk of aluminium to let you run high power for a length of time at the expense of weight. Or you could even just make your own cooling solution that uses the bolt holes to attach a watercooler or something to let you push it to its limits around 1000A if you can keep it cool enough to not explode.

    This would make it more appealing more to different markets without much additional time spent.

    Excellent idea!

    I'd make sure there's a sizable safety factor in your heat calculations. Many an esc has had a premature end thanks to too much heat.

    I would think most are not designed to be in an airtight metal box covered in foam with a massive motor breathing fire on it while being shot with 5 sniper rifles. lol

    Know somewhere with some 50cals in the UK? (Or do I just borrow carbide)

    First boards are ordered so we shall see what happens! Although it will likely take several revisions to get it right.
