Hello, All!

You have worse problems than the three phase requirement. This unit runs on 200V and 400Hz.

You need to find a converter that converts from single phase 230V 50Hz to three phase 200V 400 Hz.

????? Where in the world is the power 200V 400Hz?

400Hz usually means aircraft

In an airplane? Or an army facility? I have worked in some of them,listening to the 3rd harmonic tone going on all day, a radar facility, and air command centre.

... or an IBM mainframe.

Just replace the motor, you're not likely to find a VFD that will go up to 400Hz.

No problemo. Get one of these:

Some shops used 400Hz power internally for a lot of tools. Probably allowed them to be lighter, less iron core needed in motors AFAIK.

Yes, but also the employees couldn't steal them and use them at home!
