Hi there, this is my first time posting on here and I have (nearly) zero knowledge about motors, but I’m looking for some guidance on a project I’ve started.
I’m trying to convert my current manual coffee burr grinder into an electric/automatic grinder. I recently bought a small electric motor on Amazon (37mm, 6mm shaft, 12V, 60 rpm, 0.02 A no load, using 12V 2A power supply, and a 6mm to 6mm coupler) without much knowledge for the amount of power I would need. This motor actually almost grinds the beans, it just gets stuck too easily. So as to my next solution, I’m currently looking at Pololu’s 37D Metal Gearmotors. They seem to offer much higher torque, amperage, wattage, etc; all the fancy specs that look good. I need something that will grind the beans fairly slow, so maybe the 100:1, 131:1, or 150:1 gear ratio model.
Does anyone have any insight as to whether or not this should work? What are some things I should look out for? Also, if this is a dumb idea, please let me know why. Thanks!
