Motor choice for low speed very high inertia ceiling fan
Go easy on me, I’m a mechanical engineer and electric motors are a little magic to me. I want to construct a ceiling fan to turn a large diameter (10 foot), very high rotating inertia and heavy fan (about 80 lbs). I’m fuzzy on how to find a motor that can handle the rotating inertia to start the fan turning and run slow speed (probably 60-120 rpm). I’m hoping to run single phase 120 V to it, but could run 240 if needed. Looking to buy off the shelf motor with I assume a gear reduction box on it. I’ve thought about treadmill motors or lower end VFD pool pumps but I’m not sure any of those turn slow enough. Tips appreciated!
