Re: [CAD_CAM_EDM_DRO] phase converter

For you folks pondering 3-phase converters, I give you here a link to an
article by a machinist/electrical-engineer-wizard who is a member of and
past-president of our local Home Metal[workers'] Shop Club. It is full of
accurate and potentially-useful information. In a previous life, I built
pipe-organs, mostly wood-working, and they generally used 3-phase blowers,
sometimes powered off a single-phase line, using a capacitor-only for the
third phase. All the machinery was 3-phase. So, I kinda got to know a
little about that. In a word: If it is POSSIBLE to do it with a 3-phase
motor, DO IT! When we moved here in '85, with the intent I'd build a "home
shop" with a 1340 lathe and "Bridgeport", plus full woodworking machinery
(yes, a bit ambitious for a home-shop, but, well, it gets used rather
continuously, making pocket-change!) I made sure the local power-company
would hook me up to 3-phase "off the pole", and, to make a long story short,
After a payment of $1550 to enlarge the transformers on that pole, I am the
only "residence" on the block with 3-ph., and I have recently heard they will
now NOT supply 3-ph. for any price to a residence. Guess if iron-lungs run
only on 3-phase, you have to buy funeral insurance... IF the power-company
will supply you with 3-phase, even for $2000, DO it!
