Single phase mains

Single phase mains.

I have been running a five horse Top Well mill (5 VK I think they call it) with an Anilam 1100 controller and I have always had a problem with the bearings in the variable speed unit. (replaced
twice) So I am searching for a way around the problem and hopefully I can convert to an electronic variable speed system. I would appreciate very much hearing form someone who has taken this route
and knows the pitfalls.

These single to three phase variable frequency control units do not seem to be available in the five horse variety so I was wondering if I could down size to a three horse arrangement (I never do any
heavy duty hogging and believe that I would be much better off with a less powerful motor that could run about twice the speed of this unit that tops out at 3K rpm. Additionally I would dearly love
to do away with having to run a rotophase.

The last query that I have is about how the hookup between the VFD and my controller is done. Can it only be done by an expert, or could I do it myself??

Thanks in advance
