I run my lathe from a Transwave static inverter, it is OK but I wish I had spent the money and gone the rotary route.

I would go for a rotary converter , though they can be noisy though it was made by a "cottage industry " one man band though a rotary from a major manufacture may be quieter,I got over the noise irritation by mounting the motor in the converter set up in the shed next door to my workshop,so the set up on my elliott 00 omnimill is vertical head driven by Newton Tesla inverter and the suds pump,table feed ,and 2 hp horizontal spindle driven by the rotary converter. The reason I do not drive the the vertical head was that the mill (a gift) came with a very rough 3000 rpm single phase motor which quickly failed so I had to replace the motor ,so it was a choice of a new 3 phase motor which can expensive if a decent one is required or pay out some extra cash for an inverter drive,which considering i did not pay for the mill was still a good deal. So your Adcock and Shipley should run ok on a rotary converter.The rotary is also used to power a Meddings drill ,cutter grinder and large bandsaw without any problems. Now I also have a lathe with 5 hp 3 phase motor plus suds pump, as it was too large for my 4 hp rotary I aquired a Transwave static from a which was about to go into a skip, now this converter drives the lathe ok though I feel from previous experience of years past that I do not get the full power from the motor, the suds pump only workd when main motor runs. So a static inverterwould no doubt work ok provided the smaller motors for feed and lubrication only run when the main motor is running, if funds permit I would go for a rotary with a decent amount of extra capacity,you never know you may buy at a later stage a larger machine, I got things wrong and bought a larger Colchester triumph 2000 with 7 hp motor ,so bought another cheepo static converter which I converted to a rotary by adding a 3 phase slave motor. I did find a problem with the larger converter in that the surface finish was at times poor,initially I put this down to" Oh dear " perhaps in stronger language are the spindle bearings worn, waited until I had a job on the lathe where there was a slightly wavy finish and I mean slight but annoying so I bodged up a drive using a 3 hp single phase motor and the lathe turned perfectly ,so the fault was the converty electric supply ths is when I added the slave motor the finish improved and further improved when I changed the motor from one with an aluminium casing to one with a cast iron casing which made the finish better so I managed with this arrangement . So buy a converter from a decent up market manufacturer,( eg Transwave) preferably a rotary. Some friends who ran a steel fabrication busines some years ago bought an electronic converter but this was expensive though the cost was a justifiable expense.

I have the same milling machine, with a vertical head. You can run the coolant pump from a single phase supply with the addition of a capacitor. I ripped out the electrics from around the back of the machine, fitted an electrical enclosure, and installed a VFD. This is the cheapest and most flexible option.

I use a transwave static for my small 3 phase, Big stuff I use the diesel Genny. No messing with star to Delta and problems with switch gear Etc. Just plug and play ! Noel.
