Rewire 3 phase electric motor (OLI MVE 1700/15N-60AO) from a closed thread

If using from a VFD it would be possible, because the VFD could be programmed to provide 50Hz at 230V. But without the VFD, the motor would see 60Hz at 230V and the V/Hz ratio would be incorrect. Instead of getting the 4.6V/Hz it was designed for, it will get only 3.83V/Hz, so the motor will not produce full torque and likely run hot under the same load, shortening it's life.

What is the reason for supplying 50hz to a 60hz motor? At 230V instead of 460V the only difference (AFAIK) is the current drawn, and therefor some loss in efficiency.
