[QUOTE="robertlaurenson, post: 498269, member: 31721"] Hello everyone I have just bought a new lathe, (used) its on its way to me from other end of the country now. I have only just realised i may have an issue. The machine is 3 phase and i was intending to go down the VFD route but because its a dual speed motor im not sure i can. See attached image of motor name plate. It also says its 380 rather than 400v, its an old machine so maybe thats normal? My workshop supply is split phase, 2x100a incomers on a 3 phase cutout, no 3 phase available near me. I have the offer of a little used transwave 5.5kw static converter, but im not sure if itll work either. Any help is much appreciated Thanks Robert [/QUOTE]
