Source of brushed DC motors

D.P. · 19 Aug 2006 at 16:39

I'm looking to buy a couple of DC motors for a robotics project but I'm having a lot of difficulties finding a source of DC motors that have enough power and torque. The motors ideally need to be 12v gearhead motors with around 30kg/cm torque at something like 120RPM.

The best I have found give 8.87kg/cm torque, which will result in a very slow robot.

Anyone have any ideas or links? Please only post links if you are sure they are not competitors.

Have to see if i still have the contacts I had when we made a robot for robot wars. I'll try and find out for you.

cool. Motors as used in robot wars style robots should be perfect. Just needs to carry a 6-8kg robot at a reasonable pace, doesn't need the speed or power of robot wars robots. cheers

I'm really not sure, but I have a feeling that the type of motors you are after are similar to the ones they use in electric wheelchairs.

This is the most powerful DC motor I could find: http://www.robotmarketplace.com/marketplace_etek.html. Its 60v and 10KW. Magmotors are also good as they have a very high power to weight ratio.
