After helping VexU teams in designing custom motor cartridges based on my previous releases, I have realized that the configurable parts I produced in inventor ( 400rpm, 1200rpm, 3600rpm release
and Internal Gearing Release ) ultimately were lacking in their ease of use for creating custom motor cartridges. To rectify this issue, I have now developed a google sheet document that provides all the possible cartridge combinations between 100rpm and 3600rpm.
This sheet can be found at: Vex Custom Cart Combinations
Included in the sheet are the gear sizes, quantity, and spacing needed for each stage of the planetary gearsets in the v5 motor cartridges. In my original calculations in Inventor, I discovered an error making not all combinations optimized in spacing. In this google sheet, these results are now optimized so all combinations are balanced in spacing.
If a team successfully makes any of these carts, I will allow the team to name the cartridge in the name column.
