Servo motors, if you can get the full spec sheet, usually have 2 ratings
for torque, a continuous rating and a peak rating. So, your motors
had a 430 Oz-In peak rating, at 20 Amps. If you can find a servo
amp to supply such a peak rating, you'll GET 430 Oz-In directly out
of the motor. Now, if the continuous rating is for 10 A, that would
come out around 215 Oz-in. But, you still have that peak torque
available anytime it is actually needed (as long as it is not so often
that the motor or amp overheat).
