Gasp! The continuous voltage rating is 12 V (at stall) and 52 V peak
(at stall).
The continuous current rating is 40 A, peak is 200 A. So, the motor can
dissipate
40 * 12 = 480 W of heat at stall. I think you will have performance
problems
with a Gecko 320 or 340 drive. The biggest Rutex sounds better, but you
can barely
meet the continuous rating of the motor.

100 Lb-Ft ?!!? This isn't a servo motor, it is a TRACTION motor! You could
drive a small car with that!
