how about 3 cheers to Yamaha for publishing this stuff!!

HOnda is so stingy they want 30 bucks for the service manual (which I
paid .. I know I bitch about this all the time, but I feel no remorse for
scanning that dang thing. It's just lame as hell to withhold information
from someone who's bought three of those things over the years.) Zero
useful manuals for honda are on line from the official site that I could
ever find.

You do mean service manual when you say service manual, right?
Ya, I thought so.

Anyway here's the owners manual to the Honda EU6500isa.

Almost bought this, but got a Miller Bobcat 250 welder instead. Same price,
58% more power, 9500 watts continuous. Better resale.
More noise, less fuel efficient.

Well..a blast from the past. How are things in rec.crafts.metalworking
these days? I haven't seen you since the invasion of Afghanistan. It
was going to be over in six months. Remember that? The true Patriots
started sending me porn. That was supposed to make me see the light.
It did, so I left.

Pete still there?

Pete A? Long gone. Got a nice blog. I should ping him again and talk
sky stuff-- I've picked up a nice used Tak.

John Stevenson -- like John Woodgate in sed, long gone.

Fitch-- long gone.

Electrostatic charges are DC!

And magnetic charges aren't?

Tell me, can you make a continuous (i.e. DC) electrostatic charge without oscillating components? Can you make a continuous electromagnetic charge without parts oscillating (homopolar aside)?

I thought not :)
When they discharge the electron "inertia" usually makes them overshoot the
equalibrium and then over shoot back giving an AC with high frequencies and
lots of RFI.

ready for the RFI coming?

No, RFI has nothing to do with it.

All electrostatic generators require charge transfer, e.g. brushes, spark gaps, etc. These act in the same manner as a commutator.

A Wimshurst machine generates DC from a rotor without a commutator.

Ah, but it has brushes. If it didn't need commutation, it wouldn't need a segmented rotor either -- same purpose.

As far as I know, the homopolar generator is the ONLY generator with a rotating construction, contiguous rotor and DC output.

It's trivial to make DC from a linear motor (cf. railgun), of course, but reality doesn't allow you infinite rails or magnets.

Transformer, as in, line voltage goes to a winding around a core. SMPS don't have a transformer at the input,
they have a bunch of stuff inbetween. Physically, motors are just as transformery as transformers, though it's
certainly a misnomer to be calling them such!

No Tim; only induction motors are transformers, synchronous motors and
brush motors are not like a transformer at all.
Someone should make incredibly cheap VFDs suitable for running shaded pole type motors and legacy transformerized
equipment, then convert the entire house to DC. Way better power factorfor all those SMPS's...

How about redesigning refrigerators and household AC and heat pumps
around VFDs? Let's start where there is some efficiency reward for the
extra design work

That's funny, I thought it was a rotatary mechanical inverter. ;-)

This thread reminded of the old time dynamotors from back in the 1950s
and 1960s when i was growing up. I was about 10 or so and got to see one
running; about 250 VA i think, and not much larger than an overlong
starter of the day.
