Awl--
I acquired this incredible Engleberg 4" pedestal belt sander, but w/ shot motor, shot driveshaft, on which I've posted elsewhere.
The replacement motor is proving to be a problem. Direct replacment is possible, but expensive. (Cast iron finned, 1700 rpm, 143 frame). Rewinding is expensive.
But I've been finding possible motors, but w/ 3450 rpm, 3 ph, 1 hp.
Would this motor on a VFD be a viable solution? As a direct drive unit, I don't have the luxury of mixing pulley ratios, so would torque be a problem, at dialed-down speeds--actually, 50% speed? Would the higher speeds be any advantage for some materials??
What are people paying for these sized VFDs? TIA!
