I would like to use AC motors 1/4 to 5 HP to operate tumblers, grinders, polishers etc etc.
I'm in the process of making a large tumbler sometime in 2018, stay tuned..
Using a 1/3 HP 3 phase motor and a Sumitomo single phase 220 to 3PH 220 inverter 50 to 400Hz.. Currently looking for a low cost worm gearbox..
I got my motor from a local rewind shop for under a hundred.
