There are no internal circuit boards in the KISS.
There are no internal brushes in the KISS. The machine consists of magnets rotating inside stator coils generating three-phase wild ac. I am told that the generator bearings give very little trouble. The azimuth bearings are crap. Ill fitting and of poor design they allow the unit to rattle around on the mast. I changed them to a pair of boat trailer roller bearings and a seal at great expense for the machine shop work to make the required parts. If the unit's design would be changed slightly the expense would be slight. The two bearings and a seal are less than $15, but the machine shop work was $300 per unit. If I had know that it would be that much, I would have changed the design. The standard unit has a string on the tail that allows the unit no more than three turns until the owner must unwrap the unit again. The (optional) slip rings are mercury-wetted conveyer drive three-phase units are of high quality (and expense) that the installer wires into the feed lines hanging down in the mast after they exit the generator. This eliminates the string routine. The three-phase ac is rectified in an external control box that has a switch to short the output of the generator to stop it from spinning in low and moderate wind speeds. This switch in ineffective in high winds so I use another technique to stop the spinners then.

Bearings and brushes are the same no matter the design. Brush size is a function of brush holder size determined by the amount of current. I have on occasion had to flat file one side of new brushes that did not fit exactly into very old brush holders. Any good motor shop should be able to cross reference bearings from their master catalog. Shaft OD and press fit hole ID and bearing width are pretty standard. Anybody who can use a caliper or micrometer should be able to figure that one out. -----Original Message----- Subject: Re: [Liveaboard] repair old wind gennys KISS wind generators produced three phase wild ac that is rectified in an external box.

Thanks, Ken Pearce Ken, there is one brand which definitely uses automotive pieces right from an AC Delco catalog. Other than that most of the brands are really alternators, that rectify the AC to DC internally, so your friends advise was quite appropriate. Carl Hibbard Start the year off right. Easy ways to stay in shape in the new year.
