[mls]

Hello I am buying a vf-2 20 hp standard 7500 rpm and standard 1000 rapids
I have been reading and some people are saying its actually a 10 hp motor
and they rate them at 200 percent I will get a phase perfect unit they sell a 10 hp 20 hp 30 hp can I use the 10 hp or do I have to get the 20 hp
Thanks Mike

I have a true 10hp VMC running on a 10hp Phase Perfect. I have a true 20 hp turning center running on a 20hp Phase perfect and a 15 Haas power SL10 running on a 20hp Phase Perfect.
I'm going to think a 10hp one will be just fine. But....read the max current draw on the plate on the back of the machine and size your Phase Perfect accordingly
