2324 A 3 Phase Serpentine Coil Generator

[@richardseelye9938]

Once again thank you for your explanation and clarity doing so. The way you present almost everything allows for the simple minds like mine to actually understand the way things work and in addition stimulates new ideas. Again thank you Rob

Merry Christmas!

[@TheProspectStudios]

you are on my roster robert. your contribution is appreciated.

[@uscitizen5656]

Merry Christmas Rob! Always appreciate all of your videos and teachings!

[@chrishill1219]

Warmest wishes to you and Luke this Christmas.

[@Web3Dre]

Have a wonderful Christmas Rob

There is another advantage: In Europe, we use 230V (Single phase+neutral) for weak appliances, and 400V (between 2 Phases) for heavy loads. So you can run 2 different kind of appliances on the same wires and dont need an special transformer to do that.

Here in Germany it's almost always three fase 😉

[@andrewalexander4024]

Thank you Robert for your time as always it makes imaging things easier, have a relaxing and enjoyable holiday period

[@Kei2tahn]

Thank you so much, Robert, for your immediate reply to my question on three phase wiring! My warmest wishes for Christmas and the new year!!!

[@jkirby0710]

Always wondered if there was any benefit to using 3 phase to generate, that was probably the best description I have seen yet as to what it is and why it's not practical to use to generate. Thanks for that, and as always keep tinkering!

[@fredmoss3515]

Nice. Happy Christmas Robert all the very best for the New Year.

[@alaingrignon]

@Rob, I realize this one may be a tough one, but take some time with family to enjoy the holidays mate. What you keep giving us far out-shines what we give back to you. Enjoy Christmas Rob. I'll be looking for more of you next week for sure. Loved your explanation of the 3 phases vs single phase here, in that, maybe we should be thinking of filling that physical gap with more turns on that single phase, as opposed to wasting out time trying to properly fit 3 separate phases into that space.

BEAUTIFUL insight Robert thankyou for the upload ❤

[@Mark_Linford]

Merry Xmas to you and yours Rob 🎄

Three phase has advantages when rectifying to DC as well. This is why nearly all car alternators are three phase.

[@aldoconciso]

Rippling could interfere with the car systems, but i guess mass production costs play a role too. To simply charge a battery with no gadgets connected... just a zener to avoid overvoltage?

[@TheWorldBelow360]

Another sensible explanation. Now if I could only acquire your spark. And your ease of presentation. I’d be ahead of myself by far. Knowledge really is entertaining when we’ve got fireflies in a jar!

[@walkingbird1391]

Thanks for all the videos Rob. Merry Christmas, and all the best in the coming year from Battersea Ontario Canada.

[@ProfessorSynth]

Great explanation, thanks Rob

[@McRootbeer]

Merry Christmas Rob 🎅.

[@peterfelecan3639]

Mono-phase prevails !

[@charleselertii6187]

Thanks Robert. I have been wondering myself about the efficiency of the single phase serpentine coil generator myself. Now I see that if my desired product is DC output to a battery, then 3 phase is not really that advantageous. I want to experiment with the Ugrinsky style vertical access wind turbine with self furling features for amperage control and variable permanent magnet excitation for voltage control.

U look good Mister

[@MrTube310310]

Hi Robert, always a pleasure to watch your videos.I have learned a lot from you.I am not electrician but I teach myself a lot.What is your view about a double stator single rotor, that is taking advantage of the two poles of a magnet.That's a project I am about to tackle.Thanks a lot.

[@kittysingle]

I am thinking more in terms of coil winding safety. Three four hundred or three hundred wraps seems less opportunities for disaster than one thousand wrap coil. If I get an extra 10% out of it, I'm doing the same work regardless. One question, were I to stack three coils and offset them by 120 degrees, but keep the magnets in the same line, then wire them up, would I get a three phase or a flaming mess?

[@realorfake4765]

Would it not be beneficial to tie the outputs into a series so you get more volts if you have such a low output?

[@Warp9pnt9]

2 or 3 phase seems to be most useful in transmission, appliances, automotive, or high amps. Any rotational energy capture device of low enough power, voltage, current, is most likely going to be fine if transmitting power locally to a rectifier, charge controller, and battery bank. But should you ever need to work on a 3-phass industrial "trailer" or "conex" generator, it is definitely a plus to understand 3-phase, and a valuable learning project.

[@mikebaum5976]

Well done.

[@TheBlibo]

Would there be less of a logging effect with a 3 phase permanent magnet generator vs a single phase unit ? Great vid as always makes me think

[@RaperJason]

As usual a good video but I have a couple of questions First have you found a way of getting all three coils the same distance fron the magnets as I have tried a couple of configurations like this and the varience of at least one coil always being further away (normaly the last one fitted) produced lower levels of generation Secondly I understood the reason for using 3 phase in wind turbines was that they had less resistance so a lower wind speed start up that single phase of the same power and the ability to automaticaly brake the turbine in high winds by shorting all the phases to create a magnetic brake

[@itstackyandtawdrytime]

At 64 years of age I've gone through many phases.

[@azlandpilotcar4450]

Good lecture and demo. Can multiphase AC be more easily used for voltage amplification than DC current? IOW transformers?

[@silverpc4611]

Would the advantage be that the rotor does not have to spin as fast for an increase in voltage or current.

[@marklefebvre5758]

I would love to see some stuff on generating DC directly, rather than AC. Homopolar generators, things like that.

[@peterwilliams8890]

Have a look at the 6 phase ev nazcar so much power

[@johnwynne-qx6br]

Thumbs 👍 nice explanation

[@justtinkering6713]

Serpentine coils aren't always the best choice. Three phase currents will add together after rectification. I prefer to use three separate stators and rotors. That way each stator is thin and magnets on both sides enhance the output. I don't like serpentine coils for three phase all mashed together.

[@STRUTZKOFF]

every alternator is 3 phase generator

[@Julkkis1980]

Three-phase does not really Make much sense as You Said in normal situations. But for some reason they keep pushing qnd selling gennys for that

[@Vibe77Guy]

3 phase motors have no issues with knowing which direction to rotate. Without additional control circuitry. PWM speed modulation also works a bit better in multi phase applications.

[@Julkkis1980]

@Vibe77Guy Yes, that IS correct. And they are very effective. I was More thinking from a standpoint that in My spplications i have not required a three-phase engine for many years. IT IS harder to rectify, harder to store and harder to invert. I would not bother but for special applicatons

[@mortenjohansen5781]

Just for good measure, most car altenators a three phase to my knowledge.

[@velcroman11]

There is aways effort for you to make video your experiments. Having said that, I would appreciate seeing the 3 phase serpentine generator in action and most importantly seeing the output display on you CRO. That you for all you videos . 👏👏👏👏👍👍👍👍
