Re: Static Phase Converters

In reading some of the notes on these, I have not found the formula
to calculate the caps needed.

One site says around 70-100uF per hp.

I did find that McMaster lists run caps as continuous duty and start
caps as intermittant. Run caps of 100uF require multiples and can
get pricey.

I have a 3/4 hp for my lathe that I would be interested in trying to
use.

I will be heading out to the local scrap yard in search of caps and
relays (starters) and a potential relay.

Looking at the pdf in the files section under circuits, there is a
schematic that shows the basic idea.
