European machinery (230/400v 50hz) operating on US 208/480v 60hz distribution?
(OP)
I have recently been assigned to a local manufacturing company that is purchasing European milling machines which are designed to operate at 230/400v 50hz. One of these machines control system is designed (and wired) for 230v (L1-N). The company has wired it up for 3-phase 208 and although the motor runs, the control system doesn't operate. I have tried to explain that with 208-N you will only have +/- 118vac available for the control circuitry, and that they would need to have 400v-N to have 230v for the machine to operate as designed. The voltage distribution system within this facility is a typical 3-phase 480 panel, or 3-phase 208. My question is this: How does operating these European machines at voltages/frequency different than design specs affect the performance of the machine (i.e. speed)? My goal is to motivate the customer to purchase a large 480d/230wye transformer, and have a dedicated 230v distribution panel installed for these Euro machines. Any suggestions greatly appreciated.

Don't worry about having posted your question in this forum, most of us read both.
