For my upcoming project(no hints, but cardboard is a material) I need 2 12v dc motors to be run off the h-bridge in the store, which means the max motor amperage is 2.5Amps.
Size isn't big but the robot will be mid-sized. 5 pounds or so of torque per motor if possible.
If it could have a wheel that would be awesome!
Anyone who can link me to some motors will be put on the credits list for the future bot.
Thanks guys!
I don't know if any of these will work, but this site is reasonably priced.

You might look at this one.

Danger!, the rpm on the motor in the second link is way lower than I can deal with. Thanks for the link though.
What does everyone think of this motor and wheel?

Actually, now that I look at that one again, it is pretty slow. There are others though.
(edit our last two messages crossed)

The one that you are looking at would probably do the trick. The description mentions robots, so I would guess that it is not made just for racing cars. You wouldn't have to buy tires, anyway.
Your latest link could work, its just about trying to find a wheel.
Remember to figure the circumference of the wheel you're attaching it to. Circumference=3.14 {or pi} X diameter. The circumference is the distance traveled per revolution. Divide your revolutions per minute by 60 to get turns per second. Say for instance you have a 3" wheel and a geared motor going 120 rpm. 120/60 is 2. The circumference is 9.42. So 2 revolutions of 9.42 is 18.82" per second. Kinda zippy. Granted that the rpm rating is when not under load but you can get a better picture of how fast it may go.
ok so seeing as I'm so tired I didn't understand that what do you think is better? 300rpm with 2kg of torque or 200(152)rpm with 2.8kg of torque?
