Convert three phase 480V 60 Hz to 380V 50 Hz

I am trying to run a European instrument in the United States. The instrument consists of a three phase turbine and a three phase pump, and two heating elements that are single phase. The turbine in the pump is designed to operate on 3-phase 380 V, 50 Hz electricity. The heating elements are wired in such a way that they utilize 220 V, 50 Hz electricity. The problem is that our power in the United States is three phase 480 V, 60 Hz. This machine was built in the 1980s and is not compatible with 60 Hz.

I have been told that I cannot use a three-phase VFD to power the instrument. The feedback from the single phase pumps and the control elements will shut most VFDs down. Are any of your instruments compatible with my application? The total power consumption is slightly less than 4 kW and the maximum current is 16A. I basically need something that will convert 480 V 60 Hz to 380 V 50 Hz, but will also tolerate the single phase heating elements that operate from 220 V 50 Hz.

GoHz 480V 60Hz to 380V 50Hz Converter

GoHz frequency converter can change 480V 60Hz to 380V 50Hz, also can be connected to single phase loads.

If the peaking current is 16amps (especially during starting time), a 15kVA three phase converter will be suitable, rated current at 20.8amps. But we think the price maybe too high for it.

A VFD can be input with 480V 60Hz, output 50Hz, but due to the output of the VFD is not pure sine wave, it will make the motor heating and shorten its service life, and some older motors are not VFD-designed.

affect of frequency 50hz or 60 hz on motor stator and rotor resistance?

Dear All,
Today I changed frequency setting for my motor in danfoss vfd from 50 to 60 hz and after that i noticed increase in stator and rotor resistance by approx 3 ohms, so is it normal?
