best way for cooling motors and ESC's

**mattsdragons** · 13th March 2011, 08:32

i see most people use small fans built in over the esc's to keep them cool and the same over some motors that dont come with build in cooling, but...

were do you get these things from? they appear to be basic fans you would find in a PC. my new bot will be running with 2 9.6v batteries in series if that help on what voltage they will run at

thanks

you can get them in maplins i think.

many places, maplins, ebay etc

I wouldn't rely on fans for cooling, one piece of shrapnel or a large impact and the fan will bugger itself over. I prefer to over rate everything electronically.

I would encase the fan with a thin layer of Ali to protect it

then how would the fan be able to blow air then?

you drill holes in the ali

if you really want to do it properly you could get a small electronics box and put a fan on one side that blows cooler air into the box and so the speedo,and another fan other side that removes the hot air
