The 40 Motor Drivetrain that could've been

[moore_ryan]

So when reading through the 2023 rules I found a small rule that could’ve made a very stupid design possible. I started work on this design before the Motor Rule Changes for the 2024 Season came out making this project illegal for the 2024 season and beyond.

Overview:

• 40 BAG Motors
• Weighs 52 lbs with no electronics, bumpers, or battery
• 27" x 21" West Coast Drivetrain
• <6" Tall for low COG
• Uses combination of 4" Traction Wheels and 4" DuraOmni wheels

2023 Rule R504

R504 Each power regulating device may control electrical loads per Table 9-2. Unless otherwise noted, each power regulating device shall control 1 and only 1 electrical load.

This rule shows that 2 BAG motors may be connected to 1 motor controller and since the REV PDH has 20 slots this implies that 20 motor controllers each controlling 2 motors is legal.

5 BAG Motor Gearbox

The 1st stage is made with a .5" Hex Bore, 32DP, 85 tooth gear and 5 .125" Round Bore, 32DP, 12 tooth Pinion Gear bored out to fit on the 5mm shaft of the BAG Motor.

The second stage uses a .5" Hex Bore, 20DP, 24 tooth gear and a .5" Hex Bore, 20DP, 43 tooth gear.
Overall with the 4" wheels it should* achieve a free speed of 18.13 ft/s

There’s even space to mount a Rev Through Bore Encoder for maximum precision!
*obviously this drivetrain would not work with the high power draw of using 40 motors for the drivetrain but it was a fun cad project.

Frame

The frame is made out of Rev MaxTube and put together with T gussets and tube plugs for the a strong West Coast Drivetrain.

@Mike_Schreiber This looks like something your sim woulda kicked out

Seems like a good chassis for a T-Shirt cannon… R.I.P. 40 Motor Drive

40 motor drive in a 100m sprint… stick some blue nitrile on there, who would win?

the track, the blue nitrile would be gone in a second
