Re: Intake wheel motors

One of the mistakes teams commonly make is under powering intakes. If you've got an intake or conveyor belt, you want to put as much power on it as you can get away with.

Yes, the Mini CIM might be overkill -- but can you put a "price" on having a "Touch-It, Own-It" intake?

When I designed my first ever intake+conveyor mechanism in 2009, I asked one of my wiser friends for advice. He just told me: "The only trick as far as I can tell, is to throw power at it." I've never looked back...

I also agree that using a modular planetary gearbox is a good idea for this application. I can't count the number of times I've screwed up a gear ratio ("wow... this seems really slow!" or "hmmm... is it supposed to stall this easily?") and been saved by adjusting the planetary used in the design. This versatility will allow you to swap in different ratios (or motors) to tweak your design.

Your Mileage May Vary,
John
