How much time/work do you want to put into this motor/drive setup?
There are no really cheap large servo motor solutions unless you stumble
into a deal on Ebay or a surplus marketplace.
Larger servos generally mean 3 phase inputs. So that becomes an
immediate issue.
If you can live with a VFD, your life will be much simpler to simply get
a single phase input VFD and a suitable motor.
You can find 3 phase gearbox equipped motors on Ebay that can get you
500 rpm max.

Wondering if anyone had any preference/experience/advise to share with
single phase capable larger servos. I'm looking at an application for
a 3 to 5hp motor with a vfd, but if I could just get a servo to fill
in that'd be nice. Gear reduction will be required, but something with
more torque, needing less reduction will make things easier.Say
~500rpm as a goal maximum output.
I see things like Fanuc red cap servos (ai series? pulsecoder encoder)
2.5kw kicking around ebay. Driving something like that would seem to
be the challenge?
Thoughts? Suggestions? Previous experience?
