Re: Equivilant Motor Output

That's one heckuva spreadsheet John. I've played with numbers and setups and gear ratios for a couple of hours now. I've taken the 'super motor' over to the 1 and 2-speed drive train tabs and played with numbers there until I had a satisfactory quantity of torque values which I could take and play with back over in the super motor calculator.

Conclusion: when geared for 12 fps (bot weight = ~148lbs), if this experimental drive train even approaches stall, those window motors are toast haha. The bot would have to be less than ~85 lbs overall in order for the motors to be within safe tolerances to survive a full competition season. Even if the models are 20% off (which is the range of error I gave this experiment), I at least have a bigger picture.

Thanks alot for the help guys. I'm on vacation for the next four days so I'll have plenty of time to think of reworks and time to calculate the minimum torque needed by a worm gear setup for the drive train to perform its key maneuvers. I'll get a sketch up some time next week and a CAD later in the fall.
