peogress on the oddball generator

[pepa]

This is a few pictures of things I have been working on while waiting on parts for the petter and boiler. The stator and rotor are cut from corian counter top material which is a very strong, hard plastic material that will not warp or bend out of shape (RodgerAS came up with this idea). These pieces are prototypes for testing and making moulds if they work out as I thank they will. I threw in a picture of a new batch or vegy oil being strained and air dried by circulating between two tanks, before being processed in the cooker. pepa

save your files with a .jpg extension before you upload.

thanks allen, i have built multi-million dollar projects easier than learning to post pictures. i brought up four pictures with no spacing in title. three came up on preview and a warning that b something was not allowed on the preview. i checked everthing and only two came up the second preview. then a nessage to post new story and none came up. i,ll leave the pictures out for now. thanks again, pepa

Pepa,

Don't freak about the .jpg thing. It's easy. First of all look at my files. You'll notice the .gif and .jpg extensions to the file name. Think of it sortta like the .com or .net thing. When you save your photos onto your computer make sure these extensions are added to the file name. Make sure they're in the actual format you tag them as.

Here are your picts of the Corian work. I was suggesting the stator be machined to accept the coils. Way to think outside the box on that C magnet thing. Hmmmm?

If you want go and get these files off my section and save them again. Their tagged now.

Want me to transpose the other images so this board can view 'em?

thanks Rodger, I would like that. the design may not work but if it does it will elininate a lot of problems that i see come up in post here. magmetic flux must move in a magnetic circuit and this design is the best way to consentrate the magnet flux in a air gap between two magnets in a circuit with very little flux loss. the shaft extention that dan made for me arrived today and i will go back to work on the petter. how are the controls for your diesel coming? pepa.

That will work fine but the flux leakage will not be less than the conventional 2 disc approach.

With your arrangement you could make the gap area less than the magnet area and push more flux through smaller coils of low resistance and that may result in the better use of magnets at the cost of a heavier machine, but with equal areas as shown I see no advantage.

Flux concentrator designs have been used to some advantage with the low field of ceramic magnets but I have not seen anyone report a benefit with neo.

With the conventional dual rotor the magnets are as close to the air gap as you can get them and that gives the lowest possible leakage, the magnetic circuit is completed except for the air gap.

The conventional arrangement is restricted to gap flux densities below Br for the magnet and so is your arrangement as you show it.

As I said, it will work fine, be interested to see your final results.

Looking thru my old electric books and manuals, shows magnetic fields and transformer theory with the magnet pasing thru the gap of the "C" laminations where the coil is wound around.  I think you would get the best results with your magnets mounted on the rotor and many laminated transformer "C"s where your coils are wound.  Anyway I would like to see someone try this.

Its even been manufactured. Magnito comes to mind, there were others. They cog, a lot!

I made a tiny one or 2, 1 coil, 1 magnet (made of 2). More of a radial design. It was a total flop, but mine could have been improved some.

I don't think the theory is any different than a conversion. The coils are in a tad different place.

hi flux, i have held off replying to your comments because i respect your knowledge in a field that i am very new at compared to most of the members here. i follow your comments to others snd have learned a lot from your post. i build most of these machines just for fun and have given several to frends and neighbors that are being put to good use. one of my favorite pastimes is to try to eleminate problems before they develope in the final project. even after much research and experimenting, a lot of my work ends up in the (stupid idea-didn't work) pile. someone, somewhere has already tried this but i could not fine the right place to look, so i did some testing and so for, it looks good but will need a full stator and coil to test, and i am going to give it a shot. the benefits as i see them- 1- a single rotor moving both magnets will not have a air gap that changes once it is set. 2-the generator can be safely built without the powerful magnets waiting for your first mistake in handling (no heavy thick metal plates with opposing magnet pull that can come crashing together) you could still have a problem if you put a large magnet in each front pocket for safekeeping. 3- use of all weather proof materials in the stator will prevent water penetration problems. 4-rotor and stator can be easily replaced without trouble if damaged. 5- total weight will be less. 6- not having blades attached by jacking screws will prevent the blades from worping the air gap during stress periods. (blade arbor will be attached to shaft without contact to the rotor, while turning rotor on the same shaft). 7- the main reason for this project, heat disipation and longer coil life before meltdown. (you will have twelve fan blades rotating over each side and one edge of the coils moving air). 8- by adding more magnets to the stack you can increase the consertration of the flux. and possibly by adding more serface to the air gap, a wider coil leg can be used. 9.the best reason of all working with something that takes a lot of thought, keeps me from thanking about destroyed lungs and one foot slipping. pepa.

you could possibly get rid of the cogging by slanting the cores and face milling the gap straight at the angle of the slant (I hope that makes sense!).

If you assemble from the laminations the you can add the slant as you stack the individual sheets.

thanks for the info jacquesm, i am using lams from transformers. pepa.
