Just off the top of my head, I'm sure there's a reason robots don't go that fast. Something about tripping fuses and breakers?
Maybe you can use some Versaplanetary gearboxes to get reduction with nearly no change to the rest of the structure.


No encoders? I'm not a programmer myself, but programming for encoders seems like a good skill to learn.
CIMs (as well as pretty much the rest of our motors) are fairly wimpy when it comes to torque, so while free speed may be high, once you put any load on it at all, the speed drops like a rock. That's why we use gearboxes to trade speed for torque.
