Excelente video....

10 kw????? ahahahahahahhahahahahahahahaha­hahahahahaha

[zbrasky]

You need to make it so that once ya give it a 'push' it keeps on going-where it has it's own power source self contained-meaning that it needs-no water-no gas-no wind-no sun-no 'outside' electricity-it can be done and has been done-

10kW?, ok - at 6000 rpm?

[safdarblog]

I need a suggestion? I hooked up my 12V alternator to the battery (120Ah) directly by using a blocking diode & drove the turbine with motor & belt set-up and getting at about 18VDC. But when I connect my Ampere meter in series and noted the DC Amps there were only 1.67 amps going into the battery, while I have seen you video in which you are putting 21 Amps into the battery.

i have 10coils in series (Star Connection) 1.4mm wire & 90 turns each coil. I connected 3 halogen lamp in parallel got 10A

[speciess]

hi,can you upload the build instruccion for this wonderfull machine?

[usfootman]

does anybody knows why there suppose to be 3 times more magnets then coils? where did you got that information from?

[billmalta1]

@usfootman

Nice question u got there :o)

Because most electro or permanent magnet motor works on 3 phases AC...

-3 phases.... 9 coils needs 12 or 24 magnets, each phase has 3 coils and 3 mags passing at the same time inside them, so to be able to create a perfect AC wave you will need to setup the system so that current always passes without delay from phase A to phase B to phase C...

[Menelaos85]

I you want to create a 3-phase-system you need 8 magnet on each magnet plate and 6 coils. It is 1/3 more magnets than coils...always!

If the number of coils and magnets is equal, you will end up with a single phase generator and must connect all coils in series.

Detail ?

Hi, you look like you know what your doing =D - Id like to know something an i hope you can help. I have an 18 pole stator - three sets of 6 - thats three phase. how i have my genny is with 6 magnets all north, how ever seeing another video that the guy had eight magnets for a set of 6 coils. do i actually need 8 or 6?

[Menelaos85]

It depends on what you consider full capacity. Full capacity again depends on voltage which again depends on RPM.

Example: 4 KW @ 200 RPM would be about 190 Nm torque. 4KW @ 300 RPM would be about 120 Nm. rough formula is Power in watt/ RPM*10

@Menelaos85

Dear sir,

I'm going to do a science project can you plz send me a simple drawing about the design to my email? here is my email: maltub@gmail.com

thanx a lot

[hanker8860]

Do you know what's torque required to turn the generator to the full capacity?

[captjames5]

Where can I buy one of your kits?

[Menelaos85]

I used block shaped magnets of 80x40x20mm in size.

[AntonBowie]

Did you use wedge magnets or blocks? N52?

[Menelaos85]

10 KW peak is realistic for peaks of several minutes, no doubt about this as I did make paractical tests on 10 KW for more than 15 minutes without stator temperature climbing above 60 degrees celsius. The resin can bear 135 degrees, the wire can withstand 180 degrees. Anyway, it all depends on voltage. This unit is oonly limited by current and is rated for about 30 Amps. If you go for 700 V, u can get 20 KW but then RPM would be too high for a wind turbine

[RedMarineNex]

P = VI

So 10kw = 10,000 watts

350 volts

I = P/V (10,000 / 350)

= 28 Amps

That is a LOT of current. And a LOT of power. Are you sure about your numbers?

[Menelaos85]

It is Volts of course! There is no load on the machine in that video, it is only to demonstrate open voltage.

The Generator is definitively capable of 10 KW. It depends on the settings of the grid inverter. At 400 VDC I only need 25 Amps to get 10 KW, not 100 Amps. At 100 Amps, for sure this unit will turn into smoke :-(

On a test stand I had it running on 8 KW for more that an hour without it comming even close to overheating.

Thanx anyway for your comment :-)

[billmalta1]

This is 102 volts dc...

1.6 mm copper wire does nt produce 100 amps ;o)

So ur a bit far from ur 10 kw ;o)

i gess this is closer to 3 or 4 kw generator max

Very nice project tho ;o) and very weel made

[Menelaos85]

each coil has 120 turns of 1.6 mm wire. The system is not to charge batteries but for connection to the grid. It works with the Aurora inverter starting at 60 VDC.

If you use 12 coils i would advice to use 16 bigger magnets instead of 12 as space for the magnets is limited. If they are too close together, the flux will not go througfh the airgap but instead to the next magnet on the same disc.

[SeanyK04]

Hi, nice job on the alternator. I am thinking of making a similar one, 32 magnets and 12coils. The one you have in the video, is it hooked up to a 12v or 24 battery pack and how many turns do you have in each coils and what wire diameter?

I would appreciate any help you can give me.

Cheers

Sean

[Menelaos85]

I sold that generator for material price as I ordere a big amount of magnets from china for the next one to be build. I have now started to build a unit with 15 coils and 40 Magnets to be used for a Savonius project. It is to reach 70 VDC at only 27 RPM for grit tie purpose.

Besides I have built another 10 small units that can be purchased as a kit for people who want to try this stuff themselves and do not want to bother with Laserparts :-)

@Menelaos85

Sorry just seen the explaination in the title 10 k at 350 ;o) i apologize ;o)

U might need some kind of giant blades for it like 20 feet or something no?

What kind of load are you using to read ur current?

[billmalta1]

I am currently and a 9 coils 24 magnets wind turbine (c My video) and i m starting to regret the fact i could have easyly doubled it s power by adding some more coils and mags ;o(

LOL anyway great project i love it ;o)

[bg0821]

looks good coils in resin I started working on one 12 coils and neodymium magnets block type never got back to it good luck with this I subscribed
