Not sure where to find a 60 to 120 rpm AC motor
My problem is that is takes 10 minutes or so to grind enough coffee for two people. I'd like to put a motor on it. I tried spinning it with a battery powered drill, but the RPMs were too high. The burr spun faster than coffee beans could feed. I'd like a motor in the 60 to 120 rpm range. I still need to determine the torque required. Additionally, I'd like to plug this right in to a 110 outlet. Does anyone have a suggestion on an appliance I could scavenge or the type of motor I should look to buy?
