The AM motor in question is the AM-2161, AKA the 775-5. Plenty of power for what we're using it for, but the driving design factor was actually speed. The 775-5 has a free speed of 5700rpm...and that's attached to a 100:1 VersaPlanetary with an 18t gear on it, driving a 24t gear which drives an 18t pulley which drives a 60t pulley...total reduction of 444:1. Didn't want to go with something with a 16000 rpm free speed.
And yes, we are aware of the torque ratings for the versaplanetary and are well within limits.
