Phase converter for elevator

[olc]

Elevator in a building with 240V-1Ph:
The simple answer is use a single phase elevator.

But to explore the options for the architect:
1. Has anyone successfully used a phase converter or VFD to convert from 240V-1Ph to 208V-3Ph for an elevator?

2. Does it matter if the elevator is a regenerative type?

Is this for a new elevator?

Most single phase elevators use a vfd to convert to three phase for the motor. I had a building that was three phase, they put in a single phase elevator! It had a vfd. I had to upsize my feed to it because it drawed more current, and of course, it was on the far end of the building from the service.

2- AFAIK you can't regen back to the line through most (any?) VFDs unless they're explicitly built for it.

I'd expect the elevator mfg has a lot to say about VFD vs rotary phase converter vs just-get-a-single-phase-elevator .

This company makes phase converters that are supposedly suitable for at least some elevators. You'd have to ask the company whether their phase converters can handle elevators with regeneration. I've no experience with their products.
