You might consider the Dewalt 24v brushed motor. Good power, cheap and proven on the battlefield.

Sam, is that the motor you used to power NST's bar?
If so then i will look into that. Where did you get yours from?
Just found it on robot market place, and it looks ideal. Would i need a gearbox?
Sorry for all the questions and thanks for the suggestions.

Yes you will need a gearbox. You can also purchase those on RBMP

It's one of the best brushed motors around, maybe that some high end brushed RC motors can push more power, but you'll pay a premium then.

Yes. Even if only to protect the motor from the full brunt of the hits. The motoraxle is rather slim compared to what we see as needed on disks and drums.

I think these are the drills with those good motor's/gearboxes that NST uses.

They occasionally come up very cheap on ebay.

just going back to the wheels.
I got some of the red 100mm robochallange wheels if you would need them later in your project just send me a pm
And join me with my adventures to find a powerful brushless motor.
99% utter junk :/

Thanks for the replies, i will get some of those motors soon. Anyone got it's dimentions, as i will probrably have to make the base plate bigger for 2 of the motors. Archie i have a suggestion for a very powerful brushless motor:http://www.scorpionsystem.com/catalo...0/HK_7050_340/

I'm not sure why you would ask me but ok.
that motor seemed quite bit costly and overpowerfull.
why don't you try hobby king and search hy outrunner weight.
they have motors less than 200kv
I think the more winds you put into a motor the more tourque it has so more winds = more weight
I think that's why heavier motors have lower rpm (usually)
