I bought a 3ph machine, one is 3HP and I'm considering another that is 10hp.

So, could basic questions. Do I buy VFD's with the identical HP ratings?

These are basic machines, without anything digital going on. One is a mortising machine (Felder 250) and the other is a planer. Anything I should be concerned about?

I'm considering one more machine later on, which is a big big jointer, I'd like to use the 10HP setup for both machines (not at the same time of course), is this possible?

I can manage with electric but I'm not an electrical engineer so talk slowly and loudly

Cheers
