The original stator core was meant for real high rpms to produce anything. A special stator core is wound to produce volts at a low rpm like a wind turbine would do.

[@nothingelsetolose7661]

Thank you for making these instructional videos I learned so much from you and truly appreciate it. I am a totally beginner I feel like an idiot for even asking this question but on the magnet arrangement do they alternate from North pole to South Pole and is it this north pole and south pole presentation over the coils that produced the induction of AC. is that right? and how much torque or how difficult is it to turn the shaft of PMA do they spin effortlessly or does the magnets have some resistance

[@jimthomas777]

@@nothingelsetolose7661 , The Magnets are South then North as each Magnet comes around , That's what AC current means , it alternates , And there is some resistance called Cogging , the more the magnets are at a slant , the less the Cogging effect , and I left my fan blade on to help keep it cooler , I tested mine at 3600rpm for 30 minutes and it got warm but didn't get hot , the fan keeps it cooler , I also drilled extra holes in the back for more air flow, just remember not to drill into the diode block

[@mafelkins]

Thanks for the education, where did you get the DC parts from

[@MissouriWindandSolar]

They are used in wind turbines to generate power.

[@TysonCapel23]

Could you use a constant current pulse width modulator to regulate the current so it would work on a car?

"How to build your own...": buy our rewinded stators and our rotors.... It's not the way you build "your own". It's not DIY!

[@Iowa599]

@@skeetorkiftwon that would be making an egg...

[@jimthomas777]

Fix Man ,You can rewind your own stators and build your own rotors if you want , Go buy the copper wire for the stator , Then buy the high strength neodymium magnets and build your own rotors , I got a G.M. 12si alternator , Removed everything that Jeff told me to , then brought one of his rotors for around $50 bucks in 2016 , Put it in my alternator case and made a whopping 19 volts at 3600rpm , and in a 12 volt system that is great , that would certainly keep 12 volt batteries charged up , but they don't spin that fast on a wind turbine , this was for testing purposes only , these P.M.A.s can produce 1200 to 1800 watts depending on how fast they spin , the higher the wind turbine is mounted , the more wind it will get , I bought 4 rotors , they all work , I have one for a V.A.W.T. , one for a Water Wheel , one for a bicycle and one for a 40cc chainsaw engine for backup , These 4 P.M.A.s can run my house , plus I have Solar panels , So either build it all yourself or save some time and money by simply getting a rotor from Missouri wind and solar and if you want it to produce even more power , get the stator too , Or try building everything yourself making and correcting your mistakes as you go , You can make your own gasoline from crude oil but I like getting mine already made at the gas station

[@TysonCapel23]

Would you be able to use capacitors 2 cap the voltage so it can be regulated.

[@MissouriWindandSolar]

There the same. The 12 si just has the larger vents.

[@sure5291]

how you gonna regulate the voltage to 13.7v. ?????

[@jimh712]

The rectifier in the backof the case takes 3 phase A. C. Power and converts it to D.C. power Wouldn't be better to ship the A.C. power to the battery bank area then convert it to D.C. power.. (smaller wire for A.C.)

[@JoseTinDines]

an excellent job. thanks for showing us these techniques... I would appreciate more specifications on the magnets and the kind of current that can be obtained as well as the most suitable uses for this

[@125varma]

What is the difference between the size of magnets in 100amp alternators and 60amps alternators? Do 100amp ones have bigger/stronger magnets or just thicker and longer wires are used for windings?

[@scottymizzo415]

how do i get the right kit for the alternator GM alternator but what kind of car did that one your rebuilding come out of also what is the cost to replace the rotor and the stator to make it a pma ? thanks for the info the video was cool

[@pazdaalma442]

@Eric I have watched many of your video's also from other manufacturers including China. I think your approach makes the most sense. What strength are the magnets, I see they are single poled? Well I just ordered my 1st one from you (7 blade complete unit with Freedom 1600W PMA) and I am super excited to test it at my place in Mozambique. Thank you for all the tips here on KZbin. It is already shipped here to South Africa .....

[@martinbisschoff988]

@Paz Da Alma. From a 'neighbour' in South Africa. Great news friend. Please keep us posted if you will be so kind? News such as are you going to use wind or water power? Power yield? Will appreciate and good luck!

[@bricewillis6751]

It would be nice if you showed us the output of the end product for future videos.

[@graham6411]

Do you publish torque/RPM/ Power out curves?

[@H0B0J03]

Would having an aluminum casing with an inner ceramic surface(for rigidity) encapsulate magnetic flux and help reduce external electromagnetic interference? does that matter? would it increase efficiency of an alternator? it would possibly be lighter, but what are the magnetic implications of using a paramagnetic metal for the housing? would a diamagnetic housing work better?

[@eno9111]

Sir what wuld hapen if you force 2 like poles together ? Wuld that thing do some thing? Similar to pulse generator with out diodes? Perhaps use only capacitors as voltage and amp reference wuld that work? Because those pm alternators look similar to magnetos so I was wondering what results you get if you reverse the polarity with magnets? Im not shure if you culd get dual out put on slip rings and on stator coil?

[@marcomessina]

What power does it generate at what rpm?

[@NM403NM]

Hey Jeff i have a question about the 10si or 12si..Is there advantages form one too the other ??? Are they just as equal besides the bigger vent in the rear of the case on the 12si ? Thaks again, Eli

[@MissouriWindandSolar]

A brushed motor is just that, an electric motor being used for a wind turbine motor. It has brushes that will wear out quickly and must be replaced if you can find them which is hard to do. A permanent magnet alternator has no brushes and is made for wind turbine use.

[@robertotorres8999]

it is possible to obtain 250v 60hz from this magnet alternator, I have one that I bought several years ago, the mill removed it but I hardly use it and I have that new device and I would like to know if I open it and change the configuration of the slicker to get to 220v

[@guruji243]

Hi regards. That magnet formation creates clogging. I saw others doing them slantted. What do you think? Thks.

[@Maxttor]

I´d like to use this like motor with a 1500w 48v controller

[@jylp4u]

I remember this video too and I've been meaning to ask you this but I would always forget... Can this PMA be used as an alternator in the cars the alternator comes from?

[@Rizik1986]

The amount of amps created is determined by what? I'm still learning and seems my diy system I want to build is limited by amps.. Meaning I can't produce enough amps in my current design to run everything in my garage so I'm trying to sort out how to scale up from 5 or 10 amps (using solar power) to about 30 (using an alternator Any advice would b wonderful! I've been all over Google for days and days and not really sure why I can't find a fairly simple answer for a simple man

[@coterraneo]

Los alternadores vienen con imanes. Eodimios o se le agregan

[@hyperqbit7246]

Could you guys figure how to build wind turbine like Spanish company Vortex Bladeless? The Vortex Bladeless design seem friendlier to implement in cities, where space is limited and safety rules are far more stringent.

[@WayneStcroix]

Can you use this as a backup second alternator in your car in case the first alternator that came with car doesn't charge the battery

[@TroyDoucet]

I am looking for a brushless PMG that produces 12v DC and 1.5a with low torque (under 1 Nm) and low RPM (under 200) under a load requiring 12v and 1.5a (a water pump). Can you manufacture this or recommend a resource?

[@jameselliott9397]

Does anyone know of a software to simulate building PMA and axial flux generators where we could change coils, ohms, wire sizes number and sizes of coils and flux powers?

[@ClarkWhite81]

HEY JEFF, I have a very *IMPORTANT* question! will using the varnish affect the magnets field making the alternator slower? and also will it keep the heat inside?

[@jimthomas777]

I'm not Jeff , but NO to both questions Neodymium magnets are very powerful and a thin layer of varnish sealer has NO effect on performance , and heat is going through one end and out the other , there is ventilation holes in the front and back of the P.M.A.

[@H0B0J03]

what is the orientation of your magnets? are your permanent magnet aligned with inward or outward flowing flux? by that i mean, are the poles of the magnets facing the coils, or are they radially oriented with opposing poles facing each other? i prefer it when the poles are oriented radially with like-poles facing each other so the flux of the like-poles would converge between the magnets and radiate out towards the coils, increasing the range and overall density of the flux

[@Meta369]

I would think orientating the magnets towards each opposit with a gap would also create more EMF . After all that is how earth works. The nothern hemisphere and the southern hemisphere with the the tropicsl gap between which creates its EMF. Except realise earth is flat, in the flux of its moving toroidal field coming out of its center, above the Arctic centre.

[@Vectoast]

Hey, I've got a quick question for ya Jeff. I'm trying to make a very efficient alternator within the price range of $250 for some generator experiments and I'm trying to decide what the best configuration would be. The alternator is going to be generating energy from a generator which will have anywhere from 50-1000 pounds of force rotating a axle at the scale I'm working with. So, from your experience, what would be the ideal alternator type and stater coil to plug into a alternator case?

[@THEMFORMATION]

Interested in your findings. Am doing similar research now with the latest universal electro magnetism revelations that have been brought forth by the censored truths of this world!

[@nagarajanadhyam365]

Dear Robert, Can we connect this alternator to EV DC 48 Volts for continuous running providing switching unit for start and for running current can we use this alternator How much will be maximum current obtained from this unit How can i get in touch with you in this project

[@enriquesalgadoaceves9017]

fyi there is no replacement stator, if it was it would have to be the exact size as the stator housing, basically the stator has been rewired, you must take the stator off, learn about wiring DC motors and do your own rewiring, the amount of magnets is crucial to the amount of coils, and energy output, if you find an old motor and try this it may not work as well if the old alternator is worn, or burned, so if you find a semi new one its way better, the neodymium magnets you can get from eBay or amazon I recommend getting cylindrical shapes, if your going to use a drill to make the holes, unfortunately a mandrill or angle grinder dosent cut the rotor as well you would need a special machine to cut the rotor nice n smooth to get the nice finish so a square magnet can enter and not get stuck to the stator/housing, after you get passed all that, then you must get past the reinsertion of the rotor with its new magnets its inevitable that the magnets will stick to stator/housing so be careful not to get cut or hurt, all this takes time and research, not an easy task but definitely not impossible, I have been trying for months on spare time and its not easy mainly because I'm on a strict budget, but start with stand fan motors its a lot smaller and easier, once you get the gist of it, you can work your way up to bigger motors and better ideas

Yes you can, and they do. We have free power now. secretly they have large generators with permanant magnets . They use compressed air to start them up.

Just throw the cooling blades out we don't need them that's actually a good way to cook a alternator i have 4 200amp alternators driven by the river on my property there hooked to custom transformers that step it up to 240volt from the 14 thats comes off the stator then its turned to dc and then turned back into ac were its synced to the grid and i sell the power

The cooling fan is not needed in a wind turbine. The air passes through just fine.

Before you cal those engineers that build car alternator's stupid do research.If they install permanent magnets like in this video, the alternator will overcharge battery and blow electronics in the car in within the minute,brushes and rotor are regulators for magnetic flux do the changes on car rpm's , higher the rpm lower current trough rotor coils and lower voltage on stator and opposite, if you install this kind of "alternator" in the car and say on 1000 RPM you got 12 V , what will happen when you are on highway and driving 3000 RPM what do you think? Take it easy, do research, this alternator is good for what is meant to be with steady rpm but DON'T try in the car

[@4dscreenart]

Well I don't think this is going on a car but instead it is going to be getting used on a wind turbine in which a normal alternator wouldn't work.

[@Rizik1986]

maik vasalos alternators are simple really 12v goes in to energize the electronic magnet to create the charge.. With permanent magnets every spin directly creates electric since the magnets don't need energized.. And the faster its spun the more electric its not as easily controlled and easy to mess up

[@gordonlawrence3537]

If its got magnets then its a dynamo not an alternator. Alternators do not have magnets by definition.

[@richardschofield2201]

Gordon, your talking nonsense. Any generator that produces an AC current can be called an alternator. Your example of a dynamo is basically an alternator (can be permanent magnet or field coils) with a mechanical switch (commutator) used to output DC. Your understanding appears to be limited to what's fitted to cars and what we call them.
