There is no advantage to oversizing the VFD. Buy the 1 hp model.

You will get plenty of advice on building a phase converter. Forget it.
The advantages inherent in having variable speed completely outweigh the
possibly lower costs of a homebrew phase converter. Most of the top of the
line tool room lathes have a mechanism for infinitely variable speed
control on the fly. Once you get it, you will know why.

I only have 220 single phase in my shop. I got a super deal on
an Emco compact 10 lathe-mill that has 3 phase 220 3/4 horse
motors on both spindles.

In reading the threads on the rotary and static converters it
appears that the cost to rig something is about as much as
getting a 220 single phase powered VFD with 3 phase output.

I am looking at Teco-Westinghouse unit. and will most likely sped
the few dollars additional for the 2 HP/7.5 amp rated unit.
1 hp/4.5 amp 182$ +SH
2 hp/7.5 amp 246$ +SH

Anyone deal with them? Anyone have experience with the
Teco-Westinghouse VFD converters?

Thanks in advance for your advice or war/sea stories.
