I have not had a chance to look at everything but from what I can tell so far these are the motors in order of wattage:
- 4 - Old CIM (340W)
- 2 - New CIM (270W)
- 2 - Fisher Price motors (170W)
- 1 - Bosch Motor (70W - based on old 12V specs of 35N-m stall & 75RPM Free)
- 2 - Globe Motors (50W)
- 2 - Denso Motors (25W)
- 1 - Mabuchi Motor (15W)
Am I missing any? I suppose there is the servos that are probably more powerful that 1W*, but they are harder to get continuous power out of since they don't automatically keep putting out work, they only do continous work if your program does some fancy footwork to keep the things moving (winding a mechanism or something I suppose is possible, but probably not worth the bother).
There is an very nice, rich set of motors for teams to pick from. Well done FIRST.
By the way, I am in the process of evaluation
THESE MOTOR/GEARBOXES from BaneBots.com. For about $40 you can get gearboxes that the Fisher-Price and the Mabuchim motors will just bolt to. They come in a variety of ratios (5:1, 16:1, 20:1, 25:1, 64:1, 100:1, 256:1). The gearboxes have nice mounting points and long, easy to access (and support) D'ed shafts. And I just talked to them yesterday, they have 1000's in stock. Look for my recommendation or my non-recommendation early next week. I have no connection to these guys at all, I just found them on ebay a while back while looking for stuff for Robotic Amusements.

P.S. By the way, I have just found a table in
this document that I believe is in error. It has the peak power of the FP motor over 300 Watts. This does not match the specs in the spec sheets or even the specs in the rest of the table in the same document. I believe my numbers are correct. Also, the Bosch and the Globe are listed as non-12V specs you have to scale the power ratings accordingly to get apples to apples comparisons.
*this message was written before I had corrected an error in converting g-cm's to N-m . I had the Mabuchi at 1W, when the motor is actually 15W or so. I have since went to the
hitecrdc spec site for the 323HD servo. If I have not made another calc error, the servo motors are able to put out about .5W or so if you can load them at their 6V peak power point -- not exactly what you would call a real workhorse.
