ECN Forum Forums General Topics of the Trade General Discussion Area Rotary Phase Converter for elevator

Are we still on topic?
An existing building with 240V-1Ph. The new elevator is 208/240V-3ph.
American Rotary and Phase-a-matic are two manufacturers of rotary phase converters.

Someone mentioned a VFD. Can a variable frequency drive be used?

I have yet to meet a elevator manufacturer who would install anything on the line side of their equipment (like a transformer).
