I was hoping the speed controller would allow me to use direct drive.Belts and pulleys?
Im making one from scratch based on the Triminator.photos of your tumbler setup would help (if you have one).
now - are you wanting to modify an existing tumbler or make a new one from scratch ?
what will the drum be made of ?
It depends on the load. How much current you will need. On the motor it should give you a FLA number or current requirement. Your controller should have overcurrent protection. Could be a fuse. You could play around with it and see.I was hoping the speed controller would allow me to use direct drive.
It tumbles dry cannabis buds. They weigh very little.I am not sure what the tumbler is supposed to tumble, but anyways, first you need to estimate what speed you want it to spin at. I will guess that to be 300 RPM max.
Next we look at what speed your motor can run. My guess is full speed is in neighborhood of 3000 RPM . The nameplate on the motor should tell you.
So you need about a 10:1 speed reduction, not direct drive.
I think thats a PMDC motor. At very low voltage/speed, I don't think that motor will have much torque available to tumble what is in there.
A gearbox would be ideal. But that would be pretty expensive.
Next best would be belt and pulleys as suggested in the first reply. But you will have difficulty achieving more than 2.5 or 3:1 reduction.
Sorry missed your reply.OK, so then I am guessing that you want it turning at something like 20-60 RPM
That helps to define how much ratio you need. I still would guess that motor runs at about 2000-3000 RPM at full rated voltage.
What is your plan to support the barrel that will be turning ?
I need to collect the material that falls out and it’s sticky.Throw your cannabis buds in a cloth bag, and toss them in your clothes dryer on tumble dry, no heat.
