In article , Eric R Snow says...

So what is better? Using a well balanced RPC and all 3 phase motors or
using single phase motors with no balancing caps. As far as the
electric bill goes. With power being metered without the power factor
being metered.

Because the majority of power is spend doing mechanical work,
I would say that when you are said and done, they will be
the same, within five percent.
