I've swapped 575v for 230 and there can be lots to replace.? You need to be sure of the IEC frame size and then see if? 7.5 230v motor can be had in that size and shaft length for a reasonable cost.? If not you are swapping pulleys and belts and modifying the base plate. ? Since the existing set up probably pulls about 10 amps and you are upping it to 17-19, you need to see if the contactor modules need to be upsized as well as the overloads.? You want to check that the internal wiring will handle the increased amp load ( I would guess it will as the machines are probably wired to handle all voltage choices ).? The conveyor motor needs to be checked too as it might run on 575 and need swapping.? I don't know how many or what type of motors are in the machine but my SCMI 24" has three.? 240-575 transformers can be found cheap but the shipping is a killer as most are in Canada or far, far away.?
