Ok i am really getting sick of every motor i make melting after like 5 minutes of use! Any motor from an xspeed, iwaver pluses, mini4wd, to custom wound motors melt in my cars/trucks! Even with a ventilated bb can, carbon brushes the motors melt!
I have lithium ions and a home-made forward only drag-racing turbo(about as effiecient as a woah nelly 1.3 so it puts a lot strain on the motor...
But i have finallly solved the problem...i had heard about the big/fat commutators and decided to try them out.
They completely solved the problem! no more broken brushes or sanding down comms because of melted plastic!

Miniz-work-shop sells them on armatures but if you e-mail them they will sell them to you individually(really cheap $1 for copper or $1.50 platinum)
these commutators are very reliable for high voltage and/or hot motors

Has anybody had this problem also and what else has helped you?

Thanks for your purchase, I will give one additional platinum commutator to you for your testing FREE.

I've made a custom 21turns hand pattern wound motor, are you interested?

actually i have figured out how to hand-wind motors over a lot of trial and error...it is good to see a higher winding motor with some thicker wire used in your motors, though. the platinum is definately good, it seems like the bigger commutators actually do increase the efficiency of any motor...i swapped one of them into an iwaver xspeed plus and it made it estremely torquey and fast...of course i also put it into atomic can which equals one of my fastest motors!
