goverment will never let that hapen

[LaenPvP]

Why are there all these weird comments that say "Your Video Is Very Useful Sharing 14 perm.."

they go on to say verbatim what's in the description or title.

Something's fishy on those comments from cenedywong and lupabuatchannel. They seem like automated messages, i've seen their exact same posts on other magnet videos and they say "I really like" then copy the title or description....

62 comments, 200,000 views, someone paid for views/comments from a third-party =)

[DanFrederiksen]

@LaenPvP yeah the comments did seem a little odd. I figured they were just chinese. but I certainly didn't pay for views. I figure the view count is a result of how all important the thumbnail is for a video's appeal here on youtube

[slider2732]

@LaenPvP I've wondered about that too, especially on energy videos..good to know the video uploader isn't the perpetrator. You get such rubbish comments in forums too...normally with a link that goes to cheap knockoff shoes.

Maybe they're just so thick that they don't know the spam links won't show up.

Nice Video That You Share , So Very Nice Thanks You Iron free permanent magnet disc motor illustration

[DanFrederiksen]

@fitnesus how did you find it? just click here on youtube?

[lupabuatchannel]

I Really Like The Video From Your Iron free permanent magnet disc motor illustration

[DanFrederiksen]

@lupabuatchannel thank you :)

[cenedywong]

Your Video Is Very Useful Sharing 14 permanent strong magnets in the rotor alternating north and south pole and 21 3-phase field coils

[KyleCarrington]

Dan, if your magnet are so big, in comparison to the hole, (center part of each coil) can the voltage ever reach zero, as to create a magnetic field/effect, in the first place? I thought they'd have to be slightly smaller than the hole.. itself. If I'm making any sense lol

[DanFrederiksen]

@KyleCarrington yeah the voltage will always cross past zero because the magnets alternate between north and south (up/down) but I don't know the finer points of motor design to say exactly what design is best. I think it's a decent design but it's quite possible it could be better. I'm still learning about magnetism. it's surprisingly complex

[KyleCarrington]

@DanFrederiksen Yeah me too. You are right about ironless, though - there is no doubts there - that is the principle behind Hugh Piggotts design, of wood... Have you got his pdf? Google search "Hugh Piggott 2003 pdf" Excellent read. A friend of mine has a 2.3 kW unit made from this exact book.

[KyleCarrington]

@KyleCarrington Of course, Hugh has used an iron axle, bearing, because his units are VERY large and require huge strength. But, as you've pointed out, his stators have no iron, only coils, resin, and wood. Less cogging. We're making current, not electromagnets LOL

[KyleCarrington]

@KyleCarrington People confuse a car alternator with a permanent magnet alternator, a car alternator requires the iron, because they have no magnets! Electricity energizes the coils, with their cores as to have a magnet... at all...

[CayleyBeiseker]

I am so tired of these morons on the internet posting all this anti-physics stuff. They should be shot, not tolerated since they refuse even the simplest education in physics.

[DanFrederiksen]

@CayleyBeiseker let he who is without sin cast the first stone : )

but I share your frustration

[RattleheadGR]

@CayleyBeiseker not understanding physics is not such a huge mistake... I think that some of these "inventors" are... cute lol. They look so happy finding something almost on their own, I can't badmouth them. On the other hand there are these scammers who are actually selling bullshit stuff. Yeah, the last ones should be shot.

[TrueNevose]

It will work but will ridiculously inefficient. The simple placement of the iron core allows the coils to react more. The iron is permeable and guides the magnetic fields through the coils so they react more. If it was better this way, we'd have done it by now.

[DanFrederiksen]

@TrueNevose it was designed to be more efficient because there is no cogging and iron losses. and your premise that it would have been done before if it was good is equally flawed

[TrueNevose]

@DanFrederiksen please take a course or two in physics and read up on magnetic fields and alternating current before you respond. The flaws in this are magnetic shielding, iron core or a small lining of iron on the insides of the coils. If there is another substance that can do the job then cool beans. In this case if you do not understand that the magnetic fields will reach too far and will stimulate the coils less, go to school.

[DanFrederiksen]

@TrueNevose take a look youtube. com/watch?v=j53FIHP3bPw

between you and me I'm guessing I'm the only one who has taken actual university physics lessons

[TrueNevose]

@DanFrederiksen If that is truly so, you'd understand the flaws immediately then and not argue about factors that have to be met to make something 'highly efficient'. Yes this will create a phase and be lighter. The iron core acts as a guide for the fields. If you use iron in the coils the magnetic reaction will be more intense.

[DanFrederiksen]

@TrueNevose try to understand the difference between maximizing magnetic strength and maximizing energy efficiency. you confuse the two

[Wulfcry]

This is how some of ye old floppy drive worked.

[designine]

i like your idea a lot but a real challenge with future concern, is to have a unit not using copper at all, since we are running out that precious metal.

[jimrojas62]

The best way I think to build this device is by using Lexan and sandwich the coils and the magnets with 2 pieces each to make the unit serviceable.

[DanFrederiksen]

@jimrojas62 you need fiber or it will fly apart

[ihjmobile]

@DanFrederiksen Could i ask what program you use to make the video... It looks amazing!

[DanFrederiksen]

@ihjmobile : ) it's 3d studio max with mental ray renderer although the vray renderer is nicer to use and often produces better results

[ihjmobile]

@DanFrederiksen Thank you. Unfortunately i see on the website that the new 2012 version costs 4.370 Euro`s. That`s too expensive for me.

[DanFrederiksen]

@ihjmobile yes it is ridiculously expensive. I've even done some coding on software of my own because of it. you could always use a pirated version.

another option is using cheaper software like modo 501. I've seen good stuff from that

[ESPkenner48]

2 fallos, las bobinas no están conectadas entre ellas y siendo la base de plastico... no hay inducción, por lo tanto no hay generación, pero bueno "bonito" render.

[Darealwhip]

@ESPkenner48 ...Sabes algo de esto.??..Cuales serian las especificaciones para un generador de 5 kw...???...

[Me102288]

wind gen kits dot com has video's on how to build one of these (encasing the coils in fiberglass resin)

[MrTpengineer]

You can make the parts for the moving and stationary rotor out of plasti-dip which is a plastic that hardens once it is poured out of it's container. Stands high heat and is very easy to use. Btw you never want to use iron for any part of this device since it just makes it heavy and dissipates the magnetic field for it to work.

[DanFrederiksen]

@MrTpengineer I was thinking fiber composite. at high rpm it will need strength that plastic doesn't have.

[MrTpengineer]

@DanFrederiksen Yea that's true.

[Jebus495]

@DanFrederiksen Fiber glass resin with a splash of talcum powder for a little elasticity for areas that get cold in the winter and hot in the summer? :D

[championsanubis]

They call them pancake motors. The have been around for a long time.

Nice animation though.

[HHH100]

Waste of time with this type of generator. You will still need an external force to drive it. This device is nothing more than the committee of 300 technology.

[DanFrederiksen]

@HHH100 what? first of all it's intended as a motor, you know for electric cars. but it could also work as a generator on for instance a wind turbine or as a range extender with a combustion engine. I'm not talking about a free energy device here. I think you got confused.

[LappingMaster]

kron1.eng.ox.ac.uk/media/paper­s/Woolmer_paper_2007a.pdf

[LappingMaster]

This concept is similar:

youtube. com/watch?v=7_0X1kpYhHE

[DanFrederiksen]

@LappingMaster yes presumably but they are masters at being obtuse and getting nothing done. it could be a great design but the bastards want to keep it to themselves and never get anywhere

[GregGibbes]

Great animation Dan, but the magnets have to push the magnetic flux through a lot of air. Usually these kind of machines have solid iron backing disks to carry the flux on the rear side (not the coil side). There is still no cogging force since the stator remains free of iron.

[DanFrederiksen]

@GregGibbes well I haven't fully thought through the physics of such a design but there is such a motor demonstrated here on youtube and it seems to work quite well pushing a prop

youtube. com/watch?v=_TC57GCt37w

doesn't even appear to have tight clearance

[MadHatterTruth]

wow looks real!!

[spotlightman1234]

one problem with your iron free design neodymium magnets are an alloy of neodymium, boron, and IRON but i do get the whole point you could use cobalt samarium magnets those have no iron

[DanFrederiksen]

@spotlightman1234 I know there is iron in the magnets. by ironless is meant no iron in the stator that the magnets can 'stick' to. the idea is for the motor to be able to freewheel spin with minimal loss unlike most motors

[goose2goose2]

@spotlightman1234 miss the point much?

please send along your design for an axial flux gen/motor so we can all what

a genius you...or just shut the fuckup and learn something

[FreeMagneticEnergy2]

Nice CAD. What program did you use as it's exceptionally nice quality? Was it hard to use or can the average laymen use it? However I do have some 25 plus years of graphic software, just not automation software.

You may want to suggest the wiring diagram as well in your next video.

Thanks in advance!

[DanFrederiksen]

@FreeMagneticEnergy2 it's not an engineering program. just 3d. it's max and the renderer is mental ray. I tried mental ray because it's quite fast but I don't like how it works. you have to tweak materials and lighting and exposure a lot for it to be reasonable. a lot of things done wrong in that design. good thing I'm making my own renderer. show em how it's done : )

[YouTooArchives]

Thanks for the reply, but one of my questions still remains. Was it hard to use or can the average laymen use it? The Mental Ray program looks wonderful, but how involved is it to get basic mechanical diagrams animated like you did here? What program would you recommend the layman?

Again, thanks in advance.

[DanFrederiksen]

@YouTooArchives sorry I haven't responded before. well 3dstudio max is in many ways a messy piece of software and incompetently done and if you've never worked with 3d graphics it's probably a learning curve. but it is unfortunately the best around and once learned can be fairly effective. a video tutorial of the basics will be a good help. I found it counter intuitive to learn. with mental ray and similar it's not trivial to do good GI rendering. solidworks might be better for engineering tho.

[doceigen]

@DanFrederiksen 'Blender' works well!, but it is also counter intuitive. The real advantage is... it's FREE.

[DanFrederiksen]

@doceigen I tried it once a couple of years ago. it was just unusable. life is too short for nix

[DanFrederiksen]

@YouTooArchives btw vray plugin renderer for max produces better images and more reliably but is not as fast to work with
