Hi in an earlier post on my Emcomat 17S I got a lot of excellent advice and help, Thanks! I have now got to the next step - getting it to work. A summary, the lathe is modern and is all wired internally and I do not wish to alter any of the machines wiring. It has a plug for 415V 3 phase fitted, the machine using L1 L2 L3 and PE. By moving bridge strips in the lathe's electrical cabinet the machine will run on 230V 3~, 415V 3~, or 460V 3~. It is currently set up for 415V 3~. I want a plug and play box rated to drive the 4HP main motor with the capacity to drive the integral suds pump ( about 1/2 HP). It would also be nice to put a 415V main into the workshop since I have a couple of other machines powered from an old static converter. (the other machines are single voltage 415 3~)
It seems in the UK there are three makers of rotary converters (one SMP seeming to be a bit more modern than the other two in its design) This would be the old fashioned way on doing it. The other route seems to be a plug and play inverter but they all seem to have features that I do not want (soft start, variable speeds, jog etc) I can see this is useful if it is attached to a single machine but is not needed if one is going to use multiple machines. The other important fact is the workshop has a 35A supply that would cost quite a lot to uprate since the workshop is a good 50m from the house consumer unit. Any advice is most appreciated, regards, workwright.
