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!
Servocity.com has a few gearmotors. See if any will work for you.

Cheaper but lower torque ones are here since you're probably going to be light weight.
Consider getting a Roomba "for parts" , it will come with a couple of drive motors rated at 12volts.
Robot-doc, would they be enough?
Troy, I like the site but I priced the stuff needed and it's almost $100.
Any other sources are appreciated.
Will these work Robot-Doc? Are these what you talking about? www.ebay.ca/itm/Roomba-Discovery-Primary-Drive-Wheel-Assembly-/380235547224?pt=LH_DefaultDomain_0&hash=item5887ce0258
Or this? www.ebay.ca/itm/Roomba-500-Series-Left-Wheel-and-Motor-510-530-540-/200754973319?pt=LH_DefaultDomain_0&hash=item2ebdedca87
I found this motor: www.ebay.ca/itm/300rpm-Playmobile-Assembled-Tire-Driving-W-37GARH-DC12V-Electric-Speed-Motor-/161096782513?pt=LH_DefaultDomain_0&hash=item25821dd2b1
Will it work? I plan to pwm it down if I get 2. Has enough torque. 2 motors =9 pounds of torque. Plenty!
@Technopro Those will work, but 300rpm is a tad fast I would think... If you pwm down it won't have any torque left... It is a motor definitely meant for high speed.. I like motors of around 100rpm on the output shaft... A Roomba is close to that (100rpm or so) or even possible a little less...
Still to fast? Rated speed under load is 152Rpm with 2.8kg(6 pounds) of torque. Which leaves me a little space to pwm it down a little.

@Technopro, No problem. I know it can be pricey.
