I am patiently waiting for you to fill the whole way around with coils, would love to see how much it would generate, great video once again guys.
I absolutely love these build videos! There's alot to learn!
I like how you explain at the end of the video exactly what your trying to accomplish for those that want to be given the earth on a silver platter, What you have shared with us so far is fantastic in my opinion, I appreciate the time you have spent researching and sharing this with us in the event of a power failure we have some lighting, I would like to suggest having the lazy Susan on the bottom and energy collection on the top, as on the top you could build a shield around it to protect the turntable electrics
Good to see the progression of this project. Hope you get enough of those coils soon, it will be good to see this working once completed.
I hope so too
It's great to see the continuing progression of the turbine. Especially the unorthodox nature of it, In that it's not meant for the conditions that are usually considered ideal for wind farms. It's not particularly windy where I live/am planning to live either, so this is awesome info and inspiration for future plans. The means of production is becoming affordable, and the knowledge and tech to make it is more accessible than ever :)
I do like to try and think a little outside of the box lol
I discovered your channel a couple days ago and am quickly working my way through these videos. It is great to see you being honest about the turbine's ability, and I love your sustainable mentality.
I'm really enjoying this project and following closely. I like the way you adapt by experiment and doing. You can learn so much, thanks for the update. Putting these videos together is not a five minute job, well done.
that is much appreciated mate - you are right it takes a fair bit of effort to video as well as do the project thanks for seeing that
Your explanation make it very easy to understand and not to have unrealistic expectations. Which put in to a future project will give realistic results. Great job and explanation.
cheers mate
This turbine is 100% more effective for me than a commercial one purely based on what it costs to buy them.
Its still a love of learning so if it only charges my phone and drill batteries then its still a WIN WIN
my view exactly mate lol - cheers
Excellent job. Batteries are the main power holders and because this type of collection of wind power works for low wind and would work 24 hours a day seems to me that it would be great.
Having home based energy production is also a great idea for relieving strain on the main power distribution infrastructure. A wind generator like this plus solar and an efficient storage system would probably go a long way towards lowering the burden on centralised power generation systems. Not to mention being much more environmentally friendly. I think you're dead right about cost being the main limiter for most people, if these systems could be made more affordable more people would be interested in them. Great work Robert and co.
Great new design, I like your ability to adapt.
cheers mate - basically I learn as I go along lol
First of all, kudos for showing us your ideas and knowledge, thank you so much! This vawt is interesting for MANY people as it is “simple”, low cost and can be made with several different materials by most people with a “left and right hand”.
You stated “low wind - low speed and low cost”. What if you make a dual vawt upon each other that turn counter wise of each other, one being the rotor (top bottom vawt) and the other one being the stator (bottom top vawt)? You would still have the “low cost and low speed” but you would increase the speed significantly. The wiring could be done with a slip ring on the (hollow) stator shaft. Probably this dual vawt would be MUCH smaller as the 80 cm unit you have now but with the same output. I am mentioning a smaller version as it will be easier to make a smaller dual version.
Basically with a dual version you double the speed, it would be interesting to know the output with the unit you have now with a speed of X and a speed of X+50% and 2X. That would give you an indication of the effect of higher speed and maybe a feeling how much smaller you could go.
A smaller version (like 40 - 45 cm) you could probably put on a pole as it will be much lighter. I mention 40 - 45 cm as I have that in my head but I would be surprised if I would be far off lol.
Anyway, food for thought for everyone who reads this and it is now in the public domain as far as it wasn’t already. Thanks again!
I can't afford to join at the mo but I really appreciate the information as in process of self sufficiency on a narrow boat, thank you x
Fantastic! I really like the lazy Susan bearing and not using steel cores with the coils. I like the fact that you've made choices, along a certain line, and are sticking with them. I wish you nothing but success!
Thank you! Cheers! It's funny how many folks try to push you down the 'accepted' line lol
Awesome work mate, I understand the issues real well on this project. It is kind of like my motor\generator all in one project, minus the motor. But I guess you could add a motor at some point that is powered by solar so that when there is no wind, light is your friend.. Cheers
nice one mate - cheers
Really good video(s) love your enthusiasm. Where I live in the foothills of the pennines the average wind speed is 6.6m/s. I think with a residential turbine you'll do well if you get 70w on average with a good small HAWT or VAWT from 6.6. You might be able to run a 40w heat lamp in a chicken coop after taking into account inverter losses etc. Yes on really windy days you could peak at 400-500w because you'll have to furl or pitch at the rated wind speed (usually 10-12m/s) to avoid self-destructing the turbine. You'll never see the the true (risky) potential from wind speed x 2 = power x 8.
I don't think the manufacturers are to blame (except some of the Chinese, I saw one sub-2m blade diameter claiming 8KW) I think customers latch on to the rated and ignore advice to check local average and install as high as possible.)
To be fair Robert I watched this series hoping to see you hit 1KW but reality kicked in and you said the objective was to harvest energy from wind speeds. Not true, your objective was to generate 1KW from a turbine coating less than £100 (or was it $100?) Anyway, it doesn't matter, a reality check for everyone and I enjoyed watching.
its really great job Robert thank you very match for this work but I hope give as all detail for this machine i want to do something like this for my village we don't have electric
In every RMS video challenge....: Find the coffee cup.
lmao, man was not meant to live on water alone
I suppose you mean tea cup
lol
@@abdullahhhk or you mug
Or the Pringles.
Hi Robert. This is a brillant idea. Every household should have a few of these generators in their backyard, with a DC to AC up converter.
cheers mate
Love the concept and philosophy. I have a slightly different approach you might like. a horizontal split off set tube design fitted to the apex of a pitched roof. this uses the roof to channel the wind into the blades.
I just welded for the first time not to long ago. I got a Harbor freight one, the cart, apron, and self darkening goggles for a 100 dollars on the market place. Thought it was good buy for a start up system. Forging will be later!!! 🤦♀️
This is a more complex system. I definitely need to watch part 1. But wow. This is cool! Thank you for doing these videos .
Absolutely spot on Robert, low wind equals low output and you right it’s a harvester not a generator but at the cost it’s fantastic. It will be great to see what the final outcome attains in real life conditions though. Keep at it it’s absolutely fascinating. Well done.
Absolutely
Love the way it evolves.. Another great video. Thanks
Awesome, thank you!
I am looking for clarification on the vertical wind turbine coil arrangement. Horizontally coiled wire work better?
Great! One idea I have always enjoyed working on with these types of projects is the idea of a “Magnetic Levitation Bearing” :) so if the magnets and the coils/ electromagnets etc... were both the inside ring of the axle as well as the top and bottom of the disk that spins. If the magnetic force is strong enough, technically the spinning part should float in the magnetic fields. Plenty of space to provide electricity generation too!
You would have to think about the heat generated... I am unsure how much heat would be generated on a small scale, but I recall a thin aluminum sheet being levitated. Person poured a pitcher of water on the sheet and it immediately boiled and turned to vapor without leaving the sheet of aluminum... would require testing and possibly a method of cooling
I've only just found this video and subsequently your channel but I must say sir you are an absolute genius. This is an amazing solution for low wind speed power generation and I hope that I can try my hand at replicating your setup soon. Maybe having more than one person tinkering with these can lead to further improvements quicker.
However where I live here in western Canada, our wind varies quite a bit from season to season (slower in the summer, much much faster in the winter) so maybe I'll also be able to see how this operates at higher speeds as well as lower speeds. Worst case scenario I just need to have two different sets of wind generators for the year which isn't too bad.
Great video. Very funny to follow the project. Thumbs up!!!
Very interesting work. I live in the Mohave Desert and the wind is always blowing here. I want to put a wind generator on my roof, with solar panels too. On a larger size I have been kinda of designing a solar powered sterling generator. Something that will put out enough power to run my AC and appliances.
Dear Robert you're enjoying research and continue. I would like to warn you that the cross section is small so the power of the wind passing is impossible to give you 1000Watts.I estimate it to give you 100-250Watts.Carry on and don't be disappointed. Happy Christmas, from CYPRUS!
Are you going to fit more rows of coils? Also when you work out the optimum speed for best power generation, you could add one larger coil with a retractable core to regulate speed (via magnetic drag) for higher wind operation.
I'm impressed that you've got room in your mechanical design for another row of coils on the stator, and room for more magnets on the rotor. If drag remains low, you could probably almost quadruple your output with another axial flux plus two radial flux "rings" on the stator. You're right about commercial generators -- On days when I drive past wind farms and encounter wind conditions that affect vehicle handling, very few turbines are turning even during peak demand. Operators feather turbine blades to extend service life. Small form, light duty, serviceable generators are a better choice.
cheers mate - even though I say it myself - it is an interesting design from lots of perspectives lol
I hope part scavenging is going well, I’m excited to see it finished and producing a result. I think your design for an urban low wind is good. I want a farm of them. Do the capacitors stay charged?
Great video as usual. I am going to rewatch the one where you built a rectifier cause I already forgot how to :D
Sometimes smaller is bigger! I love this wind harvester notion, and your device is awesome.
cheers mate
Brilliant... another take on the wind generator.. I like this one Rob..
cheers mate
I like this concept because it gives you access to some sort of power no matter what your local grid is doing, and you don't have to rely on petrol or natural gas.
I like the idea of the low speed, I believe when you get the rest of your coils you should be able to make enough power to keep a small battery charged for lights in an outbuilding or other such occasionally used building.
Oh ... Cores and close gaps between magnets and stator core material are much better in terms of performance. Slowing down of the turbine only means it is delivering electrical power so that's a good thing. Not a bad thing. Even if you optimize for low wind speeds the rpm should lower at electrical load. The way you have it now is bad in terms of power delivered. Also for low wind speeds. It's excellent for voltage as you pointed out but you moved far far away from your 1kW target power at any wind speed. 1 microwave oven transformer probably does better than 50 turn table coils wo core in terms of energy.
For demonstration purpose it is excellent. Sure.
I se what you are saying mate but it's not strictly true I think cored and coreless designs are pretty common each has it's uses depending on the situation - if you have a core then there is magnetic attraction between the core and the magnet the device has to overcome to turn and therefore generate raising the stating torque requirement - or at least that is the way I am seeing it
@@ThinkingandTinkering Hi Robert, thanks for the answer. Magnet attraction is like cycling uphil. You need energy to do that but you get it back when you go downhill. It's lossless in the end. So you need a starting torque to get the thing running but once it does magnetic attraction does not account for losses. Cores do cause losses because currents are caused in the core. This is why these cores are laminated. It does not allow current to flow from one plate to the other to minimize losses. Cores do contribute to magnetic coupling significantly which is way more important than the losses in the core. So commercial generators all will have a core. Then again, if you have an energy harvester where only a few mW output is important for as much time as possible a coreless design can be exactly what you need. But whatever you do it is an excellent project for any of us to learn something new.
@@ThinkingandTinkering it's called cogging, that's why guys that make huge wind generators have only coils, more coils, more copper, no cogging.
Size of coil has to correspond to size magnets, so voltages happen at the same time and they all add up. Then at the end you have a rectifier and caps etc.
A good book to read on this stuff is by Paul Gype I think.
Anyway thanks for sharing and learning. Gotta love it!
Thanks for sharing your project with all of us. Question? How will you address the problem of making the electronics water tight? Since this will be exposed to the elements. If you can do that, I would pay for instructions and plans. I would love this to supplement my off grid solar system. I love that you teach people to salvage things and recycle/repurpose them. I build a lot of things myself with found/discarded objects and post on my FB to encourage people to recycle/repurpose found objects. I will soon start a YT channel to encourage people to do just this. Thanks again for sharing your knowledge with all of us. You are a gift to this world.
that's simple. to be really cheap, use wax. better, use epoxy. lots of ways; this is trivial since there's nothing electrical that moves.
I think it's a great idea you can always have a bunch of them or even one high wind generator as well cover the whole spectrum
I just discovered your channel tonight. Great job on this series. I look forward very much to the final build on your roof. You would enjoy my lab and shops. We are on the same wavelength.
Wonderful series!
I think this is exactly what is needed and completely agree. Little but often power generation in conjunction with other means of generating power. This will ultimately give you the best chance at sustainability
Genius! Have you looked at the POE COIL?
Rodin. Maybe this could change driving a resonance fq!
I would drive every one of those coils with that.
Love these videos! Love the upload consistency!
Awesome stuff!!
Low energy harvest is our future. Ambience, heat and cold , vibration etc well done 👍🏻. I had an idea to increase the amps you produce, use Tesla bifilar coil powered through a ZVS circuit. I have had good results and they seem to show increased amps on the output side. So combine your harvester with another tech and you can achieve the same as the industrial version and more. Keep up the great work
I love the videos and thank you for the time and effort you put in to produce the videos. I would very much like to see each type of solution ... this solution for example ... taken to a usable end ... perhaps that could be the great comparator of one solution to the next. What would be the usable end? Charging a 100AH LIFePo4 battery say from 15% to 80% and how long does each solution take to accomplish the charging. Yes, I understand wind solutions would differ based on how much wind was available at the time ... however ... simulations could be done as with the leaf blower in the lab. The goal: provide a workable / usable / proven solution (parts list, diagrams ....) that your viewers can actually use. I would VERY MUCH be open to purchasing a solution package (parts list, connection/wiring diagram) at a cost to further support your channel and efforts. I very much would like to have [multiple] solutions to deploy to supplement (or even replace) the power I use from the main if at all possible. With work, children, family commitments, and commuting I don't have the time to experiment - but I do have the desire and the funds to purchase the plans for a proven solution (given parameters and expectations). Second goal? I'd love to have a store of 10-15-20 100AH batteries I can deploy around the home with a necessary inverter whilst the non-deployed batteries are being charged up and stored using a Robert Murray-Smith solution !!!!!!
I like the strategy of your design concept as well as the fact that you are not stuck by following convention, this is how I am with design concepts also. I regret not suggesting somethings earlier in the project, one is that you could have made a bracket so that you could have had a centre bearing top and bottom as this would have a lot less friction than a lazy Susan bearing and secondly you could have possibly made a jig to hold a lathe cutting tool to machine the surfaces that hold your magnets and coils while using the wind to drive it so that you could minimise the gap even further.
lol - I wish you had spoken sooner mate - but nice ideas cheers
Mr Robert! your videos are fantastic, experiments amazing and motivating me to try it. I have one feedback - after checking your store, i saw you can provide many materials. In my opinion it would be wise to have some video link by every material that is in your estore, so that i can faster see use of it. It may sell more and more importantly - teach more. Maybe some short video why certain material is used for, 2min example, may be cuts from other tutorials that you have made. ... Just a thought. Okay, all best and thanks for teaching us!
that's a nice idea mate - I will try and incorporate it - cheers
More then just lighting a light bulb... if it is like a trickle feed in assisting the charging of your Batteries possibly? We have an isolated ranch and no power... solar, doesn't always cut it. I enjoyed this series and your working with salvaged materials. Thanks an keeping your series in a possible building one such as that here, in British Colombia Canada. ;) We did find the little solar garden Path lights worked well as night lights. Saves gas for the generator for power tools.
A great video, and a great explanation of the differences between a commercial wind generator and your wind 'harvester'. Makes perfect sense! Also, are those cheese pringles I see near the end?? : )
Looking good, love it 👍👍👍
Thank you! Cheers!
I love this project! I'm hoping to make something similar one day. It makes all kinds of sense to try to generate in low winds from any direction to power the phantom load and lights in a house. It appears to have some increased resistance since the last video. Is that coming from the lazy susan bearing or the increased number of coils or both? I'm wondering if it's going to reach a point at which it will require much more wind to start spinning.
Lazy Susan bearings aren't that good, in fact most are pretty cheap.
I think this is great. You could put 4 of these on a roof and have it charging a household battery pack. Combine with a little solar, and even a stationary bike, and you could probably provide most of your power for your house.
Bang on dude !
Most places get low we nd speeds ... Especially if installed less than say 50 to 100 m from the ground as turbulence is the main break force ... Laminar conditions apply.
Love your design so far. Am thinking conical bearings on main support axel ... Yup ... More Dosh ... Freer spin ... Tradeoff
I wish I had conical bearings mate - that would solve so many issues - I might even go so far as to buy some
@@ThinkingandTinkering Eventually buy a couple of car hub uprights and mount it on those.
Great to watch Robert its getting out of control now you spent .20p.
Fantastic work bud. Ron. All the best.
I know crazy money lol
I just stumble upon your video and I like what you are doing. May be you have thought it out but if I may suggest, pls consider wiring the coil in series i.e every 2 coils or 3 or whatever i.s.o in parallel. Another thing if the wind blow is block from escaping to the centre of the turbine, that may give more power to the rotation of the wheels.
Wallahuaklam
I would think a fair amount of that criticism is from the claim of a 1KW generator
maybe - but it's not a claim - I think it would be a claim if it was how to build - this describes my efforts as opposed to a claim
It won't produce 100w let alone 1kw.
Thank you !
Did you reach the 1kw operating capacity? if so at what windspeed? Its a great project either way - I'm loving your channel.
sounds like 50 to 70w is no the target
Happy learning
Hey Robert. Just sat through a full set of your wind turbine vids of yours in which you repeat continuously the low wind speeds in Britain. Rightfully so. Have you got a shopping precinct near you? Howls like mad through every outside shopping mall in my city, even when it appears windless. Perhaps an idea to try there. Or perhaps even try to replicate those same circumstances in you own yard guy.
Love your videos.
U ARE A GENIUS MY FRIEND! :)
You should very easily be able to get six full out of this probably 12once it's populated which would be ideal for trickle charging a bank of batteries once you set up some kind of switching mechanism. This is exactly what I'm looking for for emergency usage for my home. I'm not particularly interested in converting to wind energy for daily use I'm looking for emergency energy storage so I can have a few lights and a means to charge my phone run my coffee maker perhaps my air conditioner in the summer when my power goes out after a storm. You could expand this slowly over time adding the proper battery is overtime so it doesn't cost you an arm and a leg and it could slowly charge away going about its business relatively unnoticed. I don't know if you're still working on this Robert but it's a hell of a good idea. You always think out of the box bravo
Those coils look like they could take 20 or 22mm overflow pipe inside them. That could act as a guide for a core to be inserted or removed from the coils via some linkage. the cores could be inserted into the coils when the wind speed is high. this would help control excessively high rotation speeds in high winds and also give a second "mode". This would make it more versatile
Rob, I put this as a reply to a comment but regarding sealing the electrical components from the weather, why not just use liquid insulation tape. It's flexible and UV resistant as well as waterproof and air tight. This way you just need to brush it on and let it quick dry. 125ml costs $10-25 delivered on eBay. It's excellent stuff and extremely versatile. Insulates over 1.3Kv / mm
What would be interesting is if you could have automatically adjustable metal cores so you could make it slow down and pull more energy in a stronger breeze
This is a good idea like a wind brake as such to slow down the spin in high winds & generate higher amounts it could have a rpm detector sensor that switches the coils out like a jukebox switches out Records & as long as the blades are made out of un breakable plastics ie graphine super batched plastics they could handel any speeds thrown at them robert murry smith
Would you be planning 4 sets of coils and tie them together in series? Do you have a way to adjust how close you can get the coils to the magnets?
I love the silent Asian builders. Shet up Shettin up
If you coat the working surfaces with spray coat PTFE(sold as non-stick spray) then you will see a great reduction in drag forces associated with the weight.
PTFE slides along PTFE with a 95% reduction in friction, so that will aid in your low wind generation(and one can coats a fair surface area for around 10£ or so a can)
that is a nice idea mate -I have some so will do it - cheers
Hi, am a ceramicist and looking to go off-grid hence coming across your channel!
You have mentioned about cutting down on friction, I have had a design for a momentum pottery wheel with bearings "similar to your setup) but the central shaft with a magnet on the bottom of the shaft and a magnet directly below +2+ or -2- I have no idea if this will work for my potter's wheel or your setup as you have blades in the way.
In reference to being off-grid, with enough of those polo looking things and more magnets could you have an inner ring of them as well as the same at the top to generate more amps, volts and power stuff, would this noticeable charge a battery bank to run beside solar panels?
Sorry for all the stupid questions I make pots not electricity 🤭
Let's harness the power of rain! We have lots of that in the pacific northwest!
Am researching a micro wind turbine 2 compliment solar into my Bluetti battery/power stn. Sunshine's erratic hence augmenting with a small roof-mounted wind turbine. Impressed by the Archimedes design. All I'm aiming 4 is 2 power all my non-essentials .. all my "toys" with renewables. (I can & atm I do charge the battery with off-peak electricity & hope 2 top it off with solR the nxt day). In a marine environment so good chance of decent wind. I like ur low wind speed harvesting idea here tho .. but I want a compact footprint & "quiet" operation. Of-course there's a plethora of commercial (& expensive) solutions out there. Anyway; "talk, talk, talk, talk, torque .. it's all about torque & efficiency"😂🤣😂
I am curious as to the blade configuration, as I have seen people claim that the VAWT do a lot better with fewer blades, as little as 2. Anyways great series, I learned a lot from all the videos!
More blades give more torque, which is what you want with a low rpm generator.
One of the ways to cut down on the cogging would be to install a second set of coils spaced 1/2 the distance of your first set on a second level with the magnets in the middle. That way, as one set of magnets is coming on to a coil, the second set of magnets would be already centered. Stack 4 sets and 2 sets of magnets and adjust the spacing to 1/4th per level and cogging will disappear.
How about a maglift setup for the wheel to remove drag? Using a pointed tip on center rod may help cut down on drag as well to help it spin more easily. Thanks awesome how you bring back to the basics....and they say you can't reinvent the wheel ha :)
the bearings are certainly still an issue for me mate
If you made the ''wings'' wider, it would funnel more airflow through the blades.
.
wind turbines like this in a city would do wonders. the small size would let them go anywhere and a few hundred of them spread out would be able to help lower the overall power usage, it wont do massive things but on a hot summer day to offset some of the AC usage or heat in the winter...
every once in a while there are those massive blackouts that take a couple days to fix, they are rare but these little wind turbines could charge the emergency lighting so your not screwed after 1 day.
Hi! Great presentation, really making me keen trying it out.
In another video you mentioned the serpentine-coil, wouldn't that be an option here too?
If you use a cup of magnetrons magnets, you can levitate the rotor and eliminate friction, the separation between coils must be proportional to the magnets, use multimeter and move the gap. Regards.
Hi Robert. You mention that this type of turbine is self limiting at around the 10 minute mark. How does this work? How do you adjust the limiting to your application? Thank you for your videos, I look forward to them while eating my breakfast before work.
Look after the pennies and the pounds will look after themselves. Love it!
Great vlog 👍👍
I was wondering how it would work with the low wind working one side an a high wind on the other side being brought into operation by a wind sail mechanical device?
Hi, i cant see anymore videos on this turbine, did you get any further with it, more coils, getting it on the roof ?
That's great Rob your a star.
My friend gets rid of scrap he always gets microwaves I will ask him if you still need some bits.
Now just a thought if the stator had holes drilled in it in the centre of the coils on strong wind days could a ring of iron shafts be raised from below by say a car Jack type of arrangement to provide a core as on strong wind days the power would be available to overcome the drag.
Would there be any mileage in thus do you think or would it make to much current and melt something?
Kind regards Kev.
Consider eddy currents in that aluminium inside that base,... ;-)
I was concerned about the same thing!!! In fact, those eddy currents may even be enough to heat the base up very considerably!!!!! Not to mention resisting the turning of the device. Glad to see that someone else also took issue!!! So, go to plastic or plywood sealed to prevent water damage...
Just found your channel, great stuff. Sense you're using a squirrel cage blower fan do you think that it would help if you cut venting openings in the blower end plates. It would eliminate static air pressure (vacuum). The insids leading edge of the blades are trying to push air out. Not as much as on a regular squirrel cage lwer with the blades reversed but still trying to blow air out. Would it be worth a try?
How about painting a little magnetic ink in the coil to improve collection.
Probably the efficiency will improve by using the leverage created by moving the coils and magnets closer to the center of the rotation of this system.
It helps to study that specifically.
could you have iron cores that rise up between the coils, when the wind speeds get high?
I would mount the coils on metal washers with big inside diameter holes. No need for a iron core. Just a iron base.
good idea mate - cheers
Once completed and installed in a real wind situation how do you intend to control the voltage ? Also what about over speed when you do get those high winds ? Perhaps switching a coil arrangement as shown earlier that slows the rotor down as braking coils ?
I'm interested to see how you will weather proof the electronics/diodes etc?
Very interested in your design, could you put up a diagram of how you wire the capacitors to the coils, and what kind of capacitors you use. Thank you.
Trying to establish whether I'm understanding properly here but in the event of very high winds, could a small amount of energy be skimmed off the top to then lift a core into place? Would this then slow the turbine down reducing risk of damage whilst maintaining output. Then when the wind does down, you could then drop the core?
I am impressed by your Wind turbine .
But I'm getting an idea in my head.
The configuration of the magnets is , logically N S N S , etc.
But what about a different configuration such as that of the Halbach matrix?
I understand that it is a bit more complex to place but wouldn't this help to focus the magnetic flow where the coils are,
and therefore significantly increase efficiency?
I hope I'm not making a beginner's mistake...
Thank's
The only critic I have mate is that I would use a three phase setup. The turn table I believe it's called would have 12 magnets and the stator would have nine coils. Now, you can increase it if you wish but I think that would be better. The last design I looked at was 36 magenets and 27 coils which was the largest one. Most are 12/9 or 24/18. You would have to think about the weight of the magnets on the turn table as well as It has to move it.
go for mate = personally I do like what I am doing - but that doesn't mean I dislike what you have suggested - I think it would be awesome if you built it and did a few videos - cheers
