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.


Are you implying that an induction motor can be used as a generator?

You'd be way better off to saw out the copper...

Well , yeah. That won't work? No magnets?

No magnets. If I recall, you can use an induction generator to *add*
power, but you need another generator running to provide the excitation.
Not true with 3 phase motor.

So, how would you use a three phase motor as a generator?

i
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.
