So at the moment, we have a hood mech that can run on two 200RPM motors. We currently have it running on four 200rpms for the next comp tomorrow, and it has worked well so far. How would we go about making it faster? I want to put 600RPMs on it, but we tested it and they just don’t have the torque. Any suggestions? pictures below.
there’s likely too much friction in one of the stages, leading to the 2 blue motors being unable to accelerate,
check all the stages for excess friction, and then if its not that, maybe there’s too much contact from flex wheel to ring, as that can also strain the motors heavily
it looks like there is too big of a space between the 1st row of flex wheels (going up from your pre roller) and 2nd row
that bit was intentional, as we are planning to use that as a reversal mech into an arm. thank you both for the advice though, I’m working on a redesign that uses ball bearings since we have them.
You have too much friction somewhere we had a similar issue and it was that, no need for bearings when that isn’t necessarily the problem. Before we could only run for 1 min and now it goes for around 5 with an even faster rpm than you.
well, it may be a friction problem, and the intake can go for porbably around 10 minutes before overheating, I’m just using the bearings because I have them, so why not, and I would like to justify buying them in the first place.
As everyone else said, its probably friction problems. You can solve this by removing a little bit of spacers in each of your rollers. maybe just 0.0625 inches. This can give the axel more space to spin. Also if its spinning too slow, you can always gear it to spin really fast

is the hood or the pre hood part the problem, also if it is the hood could we get a clearer picture of the actual hood portion.
it’s a bit of both, but let’s stick with the hood bit because we have already figured out how to fix the conveyor
