Well that is, if it is fixable. 7.5 HP Baldor Industrial Motor 110 to
440V 1725 rpm free !

The shaft won't turn all the way around by hand, but it has grease
zerts. This should be big enough for generating power for the whole
property minus the washer and dryer. Plus could switch for my
imaginary 330 and 440 machines in the future. Now for the small diesel
and learn bio-fuel aka veggy oil.

Just got it, any good sites on procedures, never took apart one this
size before. I think I have one puller to my name so I'm thinking this
might be a project. Hopefully it doesn't have obvious magic smoke loss
on the inside.

Seems like every year we have high winds and the power is off for
days. Last time I fixed and set up two houses for other people before
I did mine. The main concern is running a 2 HP 220V well pump from
300' away. Or if I had to set it up by the main power feed. Yes I know
about back feed consideration, but what if the power goes out for
weeks?

Just take it apart and see, it should be easy and is likeyl fixable.

No magnets. If I recall, you can use an induction generator to *add*
power, but you need another generator running to provide the excitation.

An induction motor can be used as a generator. Now it isn't designed
for that, so it has some limitations.

Search on Google for " induction motor generator " and you will find
lots of information, more than I want to type.

It's TOAST. Bummer

My puller could be modified to get the bearings off, hopefully they
are the same size cause I'm off to see if someone has a bigger puller.
Suppose ya have to press the stator off to get the shaft for other
uses.

It wouldn't turn cause of the 3/32" copper beads in the bottom.

Yeah, like the worst load regulation known to man.

Yes, they can be excited externally, and then made to generate power.
But unless you want to run resistive loads only, and then with around 15%
load regulation, they're not effective.

Besides, with that motor he had, he'd have blown a few hundred watts just
in excitation losses.

NOT an effective approach, especially for someone who knows nothing about
motors.

Most definitely CAN be used as a generator. Needs a few good caps -
and it needs to be a 3 phase motor to do it relatively easily.

You put motor run (AC) capacitors accross 2 phases and take power off
the third.. You need to run it just over nameplate RPM, start it with
no load, and it automatically shuts down if overloaded.

On a single Phase motor you put the caps across the load.

So, would the same idea work on a 3-phase motor, with 3 identical
capacitors, one per winding, and get 3-phase out?

That _would_ be cool. :-)

I don't like the load regulation deal, but I'm already thinking about
some kind of regulation circuit - a shunt regulator could probably be
made with a bridge and a mongo pass element, but that's terribly
inefficient...

ROI would be long, long, long. One guy is installing 10Kw units for
$25k. Even at 25 cents per KwH, payback takes over a decade, longer
if you have any maintenance whatsoever. But, you're doing something
green (spending them) and helping save the old grid. Go for it, guys!
