Does anyone know the particular output they have, and what advantages they have over Bosch 750s, LEM130s and S28-400s?
Just curious. :)

I think I need a bit more info. As any AME motor I find on the robotcombat website gives that the best they can do isnt even close to a Bosch 750.

Oeps, Thanks Woody.
1240A stall..... Hawker Genesis and Albright relais.... nothing else will supply that inside a reasonable weight and pricetag.
Using a 3S6P pack of A123s (10.2Volts) per motor, you would get around 1600 Watts out of them, so similar to a Bosch 750 at 36V.
The problem is that the stall current would still be around 600 Amps, and getting a speed controller to handle that would be tricky.
So probably easier to stick with Boschs at 36V (stall current around 170 Amps at 36V, including 10S2P A123s in the circuit)
Advantages are (or were) cheap, robust, proven. Survives high power levels. Low diameter.
Disadvantages. Low voltage (well below optimal for either solid state or contactors), high current wiring. Low torque constant, limited efficiency. Long. No cooling.
Low efficiency means you may need to spend slightly more mass on batteries to get the same effect.
Low efficiency means ...toasty motors.:)
