Hi All. Has any one out there being able to generate 550VAC 3- phase to run an Hardinge HLV-H lathe from 230VAC single phase? Lots of VFD and inverters out there - unable to locate one for 550V.

James: I generate 240v/3ph and then use transformer for higher voltage.

Hi Don,

Thanks for your comment! What type of vfd/inverter and transformer are you using. Make and model numbers would be very useful.

I've read that with VFD you can't use a transformer to step up or down but with a sine wave inverter you can.

James: i have a capacitor/idler motor system I made some years ago. Search internet for 3 phase systems.
