I have a 20 inch planer that has a 5 hp, 3Ph, 230/460v motor in it. I
was supposed to receive a single phase, but there was a mixup, and
since I am in a 3rd world country, exchange is difficult at best.
Is it possible to rewire this to run off of a single phase? I have done
wiring before, just need instructions on doing this, if possible.
No, unless you can find someone to replace the field coil with one which
will work on single phase power, can find the correct start and run
capacitors, and can find the switch that disables the start capacitor.
Doing all that would cost far more than a single phase capacitor start
capacitor run motor.

Where would you find a 5hp single phase motor anyway ?
Change the motor, or use a rotary converter (NB - not static). Good
explanations of motors and rotary conversion can be found in the
electricals FAQ at http://www.owwm.com/FAQ /
Leeson. I put one on my air compressor, not knowing the difference
between "compressor duty" and the real thing. Was about three or
four hundred dollars for a TEFC motor. I'm trying to supress the
memory of the exact amount and seem to have succeeded.
I can find no modern furniture that is as well designed and emotionally
satisfying as that made by the Arts and Crafts movement in the early years
You'll need a phase converter or switch out to a single phase motor.
The phase converter ain't real cheap, but probably a little cheaper than
a 5hp single phase. Depending on where you are, neither may be all that
easy to procure, can't even guess on that...
BUILDING A PHASE CONVERTER
Buy a phase converter $550
Buy a single phase motor $350
(check rpm, hopefully the planer is belt driven & you can change
have mfr switch out the motor or buy a single phase & sell the 3 phase
