THE FUN OF CASTING THE PERMANENT MAGNET ROTOR MOMENT WE'VE BEEN WAITING FOR IS HERE.
WE LEARN DISK PREPARATION, MAGNET POLARITY MADE FUN AND SIMPLE, MAGNET SAFETY, MAGNET HANDLING, HOW TO USE THE MAGNET TEMPLATE, PLACING THE MAGNETS, FORMING THE CASTING MOLD WITH ALUMINUM FOIL TAPE, MIXING THE RESIN / HARDENER, POURING THE RESIN, AND A FEW THINGS ABOUT THAT, WHY NOT TO POUR THE RESIN LEVEL ABOVE THE MAGNETS. WHY WE STILL LEAVE A COATING ON THEMAGNETS, AND FINALY.... THE FINISHED MAGNET ROTOR CASTING.
THIS OPERATION RAN SO SMOOTH THAT THE ONLY PROBLEM WE HAD WAS, THE CAMERA RAN OUT OF MEMORY. THIS MAGNET ROTOR IS SWEET. I HOPE YA'LL ENJOT IT AS MUCH AS I DID.
GOD BLESS YA'LL.

@eyetube64
@eyetube64 4 года назад
The friction of magnetic flux gets them warm to hot depending on the speed and the duration. Plus outside weather. When they get hot they have the risk of demagnetizing and then you just have pieces of metal. So keeping cool is a means of optimizing your flux.

I'm a rather unconventional man and I find myself not willing to conform to the ways of others. With that said, I'd like to ask a few questions of you. I have already acquired 56 of the same magnets that you have, giving me enough for 28 sets of magnets. With my unconventional and nonconformist ways,I'm doin things different

Thanks for making such detailed videos, awesome. Still have the rest to watch, but I was thinking of doing a serpentine style rotor. A neighbor does scrapping and he has a bunch of multi stand wound wire where it looks as if it would be equivalent to 14 gauge. then wind it to 3 phase set up. I was also thinking of using a 8-5/8 stainless steel plates 1/8" thick, where the corner of magnets would be about 1/4 apart. Watching your videos I am now wondering if this would work. this set up would fit into a squirrel cage (10-3/4"H X 11-7/8"D weighing maybe 2 pounds) I was going to use for a VAWT design to go on top of my travel trailer. Not being an electrician, and my lack of 100% understanding in this, suggests that what I was going to do would have been a waste of material. Any suggestions or ideas on this. Again thanks for the great in-depth videos.

Great to see this good work. May be advisable to add a mechanical attachment, a dome allen screw or three so as there is thermal expansion & contraction between the GRP resin & magnet & cast steel brake disc, so the disc does not shed the whole set up affer a heavy frost or a very hot day. Or may be some light twine, threaded through the vanes of the disc & across the resin.....dacron or may be dental floss and finish of with a coat of super glue, to fix the knots.

I don't know exactly how it worked, but I do know that the when I looked up the company they did in fact exist and were highly praised and that many of them are still up and fuctional today and are sometimes sold for a lot of money. I wish I could remember the name.

I ask myselfs, when short the coils outputs, can you still turn the magnet disk? normally this get's very heavy to do but now without metal in it how it does then. I had a idea to make one, but a vertcal one, nee a good design for that so I get efficienty as high as possible. Some do use a oil drum other bike wheels, Maybe you now a good one.

Another question Muddy...Like I said, I have 56 of the magnets (28 sets) I'd like to base my PMG on Markp0177's generator. Although, it wont be exactly like his. Rather than have a single magnet per coil like his does, I think the opposing magnet idea is a better one. His has 28 magnets and 28 coils, yet is 2 phase. I'd like mine to be 2 or 3 phase (preferably 3 phase) Have a look at his design and let me know what you think. Be prepared to answer a few more questions.

would like to know, if i measured the stator coil of a static (unpowered) motor, and i get a resistance reading on that, ...... can the resistance be calculated for estimated watt output once plugged in ?
@muddymuddymuddmann
@muddymuddymuddmann 8 лет назад
+Nico Botha good question. Actually it is a nice indicator for power transfer, But there is a lot more to it. You need to know RPMs Per Volt so you can match the prop to the alternator or motor. The size of the prop tells the expected power out that can be absorbed by the wind swept area. if the prop isnt matched, you can expect maybe 1/4 power dues to stalling, or too low rpms. As far as calculations by ohms law ect., You want a low resistance in the stator or your amps will be very limited due to heat dissipation in the stator, and overall total resistance limiting the amps. Also, in transformers, maximum power transfer is achieved when the impedances match. the same goes for power transfers from the genny to the batteries. In other words, the big example: On the ceiling fan wind turbines, The outer set of coils measures somewhere around 90 ohms, the inner set around 60 to 70 ohms. The battery is somewhere around .6 or .06ohms of internal resistance. A very bad match. all of the current from the stator and the battery should be the same because the total circle is the same. Thus where there is resistance and current, there is heat. Wasted watts being dissipated in heat watts in the stator. so maybe one amp trickle charger that works for most battery bank voltage plug and play. So to sum it up and make sense, The Closer the stator resistance is to matching the battery's internal resistance, the better. MUDDy

@kevinanderson9243
@kevinanderson9243 8 лет назад
Question....what would the output be , ballpark, if this were a single rotor and not dual? The ceiling fan wind turbines could be called single since they don't have magnets opposing them and wired properly they put out about 2 amps. Would a single rotor and stator, the way you have made your coils, generate 10-12 amps?
@muddymuddymuddmann
@muddymuddymuddmann 8 лет назад
the coils will still be able to handle the same amps, But it would take more RPMs to do the same voltage, and the same torque to achieve the amps. Although when the RPMs needed to achieve the charging voltage is reached, And amperage is drawn, The voltage drops, and requires even more RPMs. These RPMs will be under more torque. The main goal with two rotors is to lower the RPMs needed to reach charging voltage in lower winds. Otherwise it would take higher winds to even start charging. Lower winds are more common. If you used a prop around 1/2 length, That would cure the RPM problem, BUT, at a cost of 75% of your total power lost. I hope this helps. MUDDy
@paverop
@paverop 11 лет назад
Continued...I plan on, rather than making a flat stator,one that is a ring with the coils standing on edge. The magnets will be on opposing sides of this ring, standing on edge.Now I have to ask you. Should I make 28 coils? If so, how far apart should these magnets be? Meaning that with 28 magnets standing on end there would be 1 inch between the north and south ones around the circumference of this ring. With that config. how big should the coils be in relation to the magnet size?
@offgridd
@offgridd 10 лет назад
Hi scott, I really like your pragmatic approach on your project and also the sound of the wind blowing at the background ;-) Can you give me some info about the power you want to create with your setup? I an thinking of making a diesel engine powered generator ( not enough wind here...) and would like to learn how to calculate things like windings, rpms magnet field strength etc etc. Regards Paul
@muddymuddymuddmann
@muddymuddymuddmann 9 лет назад
The voltage is a parameter that can change with rpms. so using an engine will allow you to achieve the voltage desired so long as the magnets dont fly off on high rpms. The current is limited to the size of the wire in the coils. less resistance in fat wire, but less turns per coils as well, with lower volts out. as it sits right now, i hope to generate 750 watts. at 12 volts that would take 62 amps, a nice feat for two strands of 14 gage wire. two strands of 14 gage wire approximates 9 gage wire. I say two strands because two phases of coils are producing at any given time. I hope this helps. rpms dictates voltage, tourque dictates amperage. Thanks MUDDy

"I'm Scott Brown with Greenwind & other home energies". I dont know if its just the way you say it or the way its written out. But that is one catchy title. And I love neodimium magnets. The problem is they dont like me. And I got the bite marks to prove it. But anyways, someday I'm going to figure out how to utilize these magnets along with other natural forces and laws of physics and create a low intake - high output energy scource. Anyways, this looks very cool and I'm gonna shadap now so I can finish watching it 👍.

Isn't that a 2 way street? It seems to me that using a heavy rotor will smooth out the lack of consistency with the wind by continuing on it's own inertia, but it will also take much longer to get up to speed. BTW... Thanks for posting these videos. I enjoy them.
@insightsoflife6952
@insightsoflife6952 5 лет назад
nice video . but i think there s something u dont know about magnets. the magnets are magnetic because the flux wants to go treu a material as easyest and fast as possible. Hence it pulls on metal.(fero) because it lets the flux go true eassy. but when u put a magnet on a metal plate the fluxfield collapses because it found a way to go eassyer true metal then true air (permeability) lets give the field size of a magnet u hold in your hand a number lets say 10 then when u put that magnet on a metal plate the size of the fluxfield wil shrink allot maybe by half because the fluxfield wants to go true the eassyest material to go treu. then it wil be like size 5. if you want to build a windmill to produce electricity you should have magnets mounted in a ertalon or other strong plastic disk that way the fluxfield wil be mutch bigger making a bigger difference in the coil making a higher voltage and bigger amps. Voltage and amps it creates depends on .... - the strengt of the magnet N value (example N43 ) - The speed of the change going from N to S the faster the change the bigger the induction - the size of the fluxfield covering your coils (to big coils or to small magnets wil get you low V and A) coils shhould be made depending on the size of the magnets. -The ammount of windings and gage in your coils.(more windings more volts bigger gage bigger amps you can draw if there s enough wind to keep it spinning offcourse ) the more u draw power the more resistance it wil have on the magnets making then stop eventually making your proppeller stop. Second you should try to have all components in your windmil made out of NON electric guidng materials (except your coils offcours) because they create dragg. a magnet has no effect on copper of aluminium when static (not moving) but when u move a magnets fast over aluminium or copper plate u wil feel it resists the movement like its braking. so if you make around the stator a aluminium frame or tube it wil dragg out your windmil making it run slower. Olso the axle of your windmill should be a NOn ferro mettal like aluminium because if its ferro it wil pull on the flux field of the magnets making them smaller. last but not least its always best to use ass much as possible plastic in the whole design of the generator then it wil not cause dragg and it wil not pull on the fluxfield of your magnets. I have not made a windmill with all these things in mind but its allot of stuff to keep in mind to make it as efficient as possible. There s allot more to keep in mind but this is a beginning of a efficient windmill.. cheers and goodluck.

I would like to see a diagram of the magnet showing the N/S poles.... I get the impression the poles are not at the ends -like a bar magnet- rather they are on the two largest sides.... but not sure..
