I've purchased the Modern Robotics Inc (RBI) new modules from their website as well as 4 of the new Matrix 12V gear-motors. We used the 9V motors for our previous mecanum platform with good success and want to test these. Matrix has yet to publish specs for their 12V motors. There's a lot of information on the AndyMark and Tetrix motors and I want to evaluate and compare the Matrix option.
I've modeled the motor with OnShape (my first use of this CAD software). The model is "public" and may be viewed and copied by anyone with an OnShape account :

I'm setting up a test rig and will publish torque/RPM/power data next week. From what I've tested so far, the motor has the following:
- 52:1 planetary gear set
- Approximately 200 rpm no load speed
The shaft end dimensions are identical to last years 9V motor. Specs here:
