We have a motor on a machine built for 480V and it is in a building that has only 208/120. It's European but the motor in question is rated for 60hz.
On the nameplate it states 480Y 277 Delta. It's a new one on me, usually I see motors that are wired one way (Y) for high voltage typically 480 and
the other way (Delta) for the low voltage 208. It's a 6 lead motor same as other IEC motors I have worked with. I was asked if this could be wired to run
on 208 and I said to buy a transformer. How can you get 3 phase to phase 277V without using neutral or ground? It's not my job but I am curious about
this one.
