David,
?
The Felder machine/motor is still spec according to the EU grid system (230V), you can see that the motor sticker says it design to work with 230V.
The only different is the way the motor is wired (and some minor electrical component that were changed) , in delta configuration, it expects 230V between phases and in star 400V.
The motor is also running at 20% higher rate given the higher phase (60Hz vs 50Hz)
Something else is wrong here.? 230v is an old designation, just as 220 is for even older machines.? Any new 3 phase machine sourced to the US will run on either 208 or 240v.? 230 is sometimes used to reference?a machine that will run on either.? Since US voltage varies +- from 240, there is no way running at 238-242 is going to cause problems, and no way would a new machine need a buck transformer to operate in this market.
How is the machine misbehaving?? I've bought machines with a starter that had an incorrect coil, a faulty transformer, or wiring labeled incorrectly.? Spending to adjust the incoming voltage seems like high risk low reward compared to the more common problems.
