Honda E1500 generator stator replacement or repair

 

I have a Honda E1500K generator that has an open stator.  What are my
chances of finding replacement parts?  Repair?

If I don't repair this, I have a great gas engine.  I am thinking of
fitting a 12 volt alternator and using this to charge batteries.  (The
generator does not work for 12 volts either, but this seems to be the
diodes.

Thanks

 

I have a similar situation but my engine is only a Tecumseh 10 HP.  I'm
thinking along the lines of putting a big pulley on the engine shaft
(assuming I can get a pulley on a tapered shaft) and driving the alternator
at about a 4:1 ratio.  I figure this way I can run the engine at a much
lower speed and I think I'll have enough power to drive the alternator with
10 HP.  I expect to be able to put an ammeter on it and adjust the engine
speed to get the desired current output.  I ran the engine with no load at
3600 rpm and it ran about 50 minutes with one quart of gasoline so I expect
it will run about 8 hours with one gallon of gas at around 1500-1800 rpm.  I
also think the engine will last a lot longer, require less frequent oil
changes, and be quieter at lower rpms.  I'm thinking I only need about 25 or
so amps so I've been looking into the GM type one-wire alternators with a
built-in voltage regulator maybe in the 60-90 amp range.  Presumably a more
powerful alternator will produce more current at a lower speed but I imagine
it will still use as much gas as a smaller alternator to produce any given
current.  I may even rig up some kind of circuit to shut off the engine once
the batteries are fully charged.


Any comments, criticisms, suggestions?

I got some info here: http://theepicenter.com/tow02077.html  but I think my
10 HP idea would be better in many ways.

Any other links for more info in this kind of project?



An authorized Honda generator sales/service center might be able to get you
the stator coils.  I know it's available for my Coleman Pulse 1850.
I found a replacement for my Homelite stator from John Deere for about $300
plus shipping.  No thanks.

 

Are you sure it is the stator and just not needing " flashing" of the
armature . Did it sit for months unused?  It is a common problem on
units left unused for 6 months or more to loose residual magnetism , and
the repairman gets an easy job with a big bill. I dont know if your
Honda had an exciter circuit but my Generac doesn`t .  It is worth a
test rather than betting on a replacement. Even with a exciter, the
exciter circuit could be bad , and it could loose residual magnetism.

 

Thanks for the tip, but I'm sure the stator is bad.  The wires melted and
had little globs of molten copper on the ends.

Good point though.  Probably lotsa folks aren't aware of re-exciting the
armature (?).

LOL.  I _think_ that's a clue that might even catch my attention :-)
