Motors

John Board

G'day,

I'm building a robot for some International Competitions, and I need some motors... some really good motors... The specs are below:

Torque: 2.5nm
Speed: 512 rpm
Size: Unknown... About 3cm diameter though (I think), I'll update when I know for sure.

I was looking into getting motors from Maxon Motors (http://www.maxonmotor.com.au/maxon/view/content/index) (who, may I add supply motors the NASA's Mars Rover project), but, as expected, were quite expensive, clocking in at about $500 / motor, excluding the drivers, which bumps the price up to about $700 / motor, which is quite a bit too expensive. So I'm wondering if anyone knows of good quality, decently priced, easy to use, reliable motors, to the above specifications. When I say decently priced, I'm talking $250 ea, however, if you find anything under $500, post it anyway, I would be interested to look at it.

Thanks guys,

John

Ebay might have something that is pulled from equipment and far more reasonalble. I was looking at 6 German motors with optical encoders for less that $125 earlier this year. Maxon may have gotten the Mars Rover as an American supplier, but there are German, Swiss, and Japanese suppliers that provide equally excellent quality. And of course, if you can buy surplus pulls rather than brand new - the price is a lot more reasonable.

Do you really require nice and shiny new?

You might try Faulhaber minimotors.

Thanks for responding, will look into it.

Just as a quick note, Maxon is an international company, they make the gearboxes in Switzerland, the motors in Germany, and put everything together in America.
