Alternator inspection and disassembly instructions
« on: May 14, 2009, 05:27:25 PM »
Hello all --

In our Wind Turbine User's Manual, we tell readers to contact us for details on how to fabricate the jacking screws and safely remove the front magnet rotor. Of course if you built your turbine from scratch you already have the tools and know how to do this, but some folks buy the completed turbine 'kit' from us and never had to go through this (somewhat) tricky and dangerous procedure.


So, DanB recently wrote a page that describes the procedure in detail for the un-initiated. It does have some good, new information about what to look for during inspection and maintenance, even if you already know how to take your alternator apart.

The new page is here:

Have fun with the wind --

Looks good, don't see anything about setting the air gap right though? Seems pretty critical to me ..

"shouldn't EVERY get your fingers between the magnets"?


Otherwise a great job.  (Really ought to have a section on adjusting the gap.  Not just for mechanicals but also for cutin and stalling.)

Dan B wrote it. Dan F does NOT make typos like that one pointed out!


I'll take a look and see if I can expand on the airgap issue a bit for the revision.


Thanks all -- DAN F

Modified assembly and disassembly instructions

Dan(s),


I would like to propose a slightly modifed approach to installing/removing the outer rotor that you have in your manual


As you have noted in your instructions "If it gets too crooked (cattywampus) it will bind up and damage the threaded rod".


To absolutely keep this to a minimum you can put nuts on three of the studs, if you are installing the rotor turn these nuts so that they are always near the outside rotor surface. If removing the rotor back them slightly away from the rotor as you are turning the jacking screws.


I used the technique this weekend and it made it far easier to control the rotor and would highly recommend it!
