If you've got the money, there are companies making solid state phase
converters. I know of a wood shop using one for shapers, planers, wide
belt sander; and it works much better, and more efficently, than
his previous motor/phase converter did. His old equipment gained
more power with just that switch, with lower power usage.
He went to a solid state version, because the motorized version
would not work with the motors in some new equipment he
wanted to use.
I have
one. It's actually a motor-generator pair. *Extremely*
inefficient, but I think I might be able to pull it off.
You've got a nice one. :) Most phase converters tend to look like this:

The interesting property of this kind is that as the load increases, the
more balanced the phases become.
