Re: pic: Concept 6x rs545 planetary gearbox
As hinted above, this isn't a planetary gearbox, but simply a multi-motor single stage gearbox. Using this design to stack up 6 small motors is probably a waste of resources (easier and cheaper to do with a single larger motor), but with a bit of scaling up and a larger output shaft, this would be an elegant way to feed 6 CIMs into a single PTO drive train. You could get the output stall torque of two CIMs while drawing ~23A per CIM (assuming a 95% efficiency) - and achieve output speeds at that torque of around 2000 rpm.
Anyone know off the top of your head how long you can pull 130A (guessing 15A hotel load) from an FRC battery before you hit roboRIO brownout?
