My understanding is he only has single phase as Polaraligned mentions.polaraligned wrote: ↑Sun Aug 01, 2021 12:11 pm He is in a residential neighborhood, so I am sure there is not 3 phase available other than a rotary converter which I believe Mark is using to power this machine. I would drop the 3 phase, but to each their own. I run my 16x60 lathe on a rotary converter and I hate hearing it running.
The machine would certainly be more valuable on resale if it ran on single phase.
I am not sure how he got his voltage output if only 2 of the 3 primaries were connected.
Mark what is the voltage phase to phase and phase to ground on the PRIMARY (LINE) side of the transformer.
As I previously mentioned, I would jettison that 3 phase transformer and the current bridge rectifier and replace them with new ones.
If each core of that transformer is supplying the voltage to a 3 phase rectifier, because we do not know the specs of the transformer, will it be enough to drive all 3 current axis and possibly a future 4th?
Not worth the headache and chances to me....going to do it, do it right. New electronics all the way.
