[QUOTE="robertlaurenson, post: 498338, member: 31721"] It is for personal use at first but my plan is to set up a business which this will be the workshop, So i guess you could say it is for business use, This for sure wont by my only 3 phase machine and rather than sell it i think where i need to look is forward and how to get a converted 3 phase supply from what i have. I will most likely in the future have a press brake, guillotine, mill, and possibly many other things, so a converter of some sort will be required, a VFD isnt going to be an option for the bigger machines so i need to look at full workshop options going forward. As far as i can see the 3 realistic options for a full workshop are 1, Rotary Converter (either buy or build) 2, Drives Direct digital converter 3, Unique 3 Phase transformer option - just found this and reading up on it and considering buying the book to make it but not sure if it will work, any suggestions welcome. As mentioned above, if any of you have any idea or opinion which is the right way for me to go then please let me know. Drives direct are probably the one i would choose if it werent for the high cost And to be honest if it works, looking at the Unique 3 phase option seems like it could be the cheapest to make and the cheapest to run overall so not sure what to do Thanks Robert [/QUOTE]
