How to build a 3D printed ironless airgap alternator for micro-wind turbines Laplace partner of the project "light up a life" for the "WindAid institute"
@@Kerivity he kind of used the halbach array since he used the small magnets to form a symetric shape as coils In axial flux they don't use 2 stators because the other side has a weak magnetic side that's why I mean you can have 2 stators in axial flux motors its just about cost
No shit. I've argued with other channels about the advantages, but there's no accounting for educated idiocy. Would've been nice to the results of a proper contra-rotation set up though.
Excellent usage of test equipment and data acquisition. Nice to see a vid with the music jam like this and it not being blasting loud like all the others which make you switch off the sound..
Very nice video with accurate information to make you own machine. Just do not get lost in making a patented view. Look forward to see more from you Sir, DH.
the first designs of a radial brusless EC Motor from Laboratoire Laplace gave me a idea to design a Counter rotating motor. a 3Phase EC gives the Flux to turn Clockvise also counter Clockvise with self amplification. If you design Cooling Fan, Windmills , Drones etc Counterrotating Motors are Usefull and increase effiency to 40%
Hi @Dominique H, really impressive and effective design and assembly. Is there a way to make the world more greener and to share the CAD-Files for private use please? So I could 3D print them. For myself I would like to rebuild them for my house and combine it with a windmill and some gears to increase the rpm.
Wow, this is beautiful work. I like the use of inexpensive tooling (lathe) to achieve precision where necessary, while using other inexpensive tooling like 3d printing for the rest of the geometry to create a fantastically performing item using very attainable tooling and methods. (Of course, there's alot of other expensive tooling there, but that isn't strictly necessary for somebody who is re-implementing a design, rather than developing it) Fantastic work
Hey brother it’s Joey :) remember me! Just checking in it’s been a few years thought I’d see how you are and I’m glad your still kicking ass man! Love ya brother man! Btw I might need help building and biophoton multiplier… I gotta…. A … thingggggg hahaha
Good job, but because of the height of the coreless coils, the air gap is large and the flux density is less than could be achieved with those magnets. The incorporation of flat flux return back iron plates would have increased the air gap flux density, and the power output further without introducing cogging torque. The increase of the airgap thickness with coreless designs is the principal disadvantage of axial flux coreless machines.
Dominique. I made a similar BLDC Generator for a mini wind turbine. Could you tell me your conclusion about this exercise? Your generator generated 180w with load? You measured volts gnerated without load and it was 30 VDC with 2000 rpm drill , and after, when you connects load, you get 22V and 8 amps, but in the video, you manipulate de drill`s rpm to 2000 rpm again. How many ohms was there in your resistor?. I would be grateful with you if you could share some small details with us. Good, good job
Yo pienso que esta bien hacer este tipo de experimentos ,si los otros lo lograron. Este experimento se aprende...a quitar o agregar....otra cosa el rotor debe ser metalico....parece ser que el alternador que usaron es de 24v....
I did not understand the reason of using round magnets instead of bars. We missed the voice to explain some steps and specifications. Nevertheless, I appreciate the fact that you exploited the 2 faces of the magnet to maximise generation and the connection requirement this yielded. Good job and thank you for sharing.
i really wonder why you always were holding the device by hand. didn't you plan for some stand or clamping? i mean a pair of matching brackets with say holes for 3 housing screws each (or one u-shaped bracket) would have done it - and then any standard woodworker clamps or a vice would hold it in place quite nicely.
Have you tried using star delta connection windings. In large 3 phase motors this is used to go from initial startup to high speed. Does this work in reverse for generators.
Beautifully done 👍🏻 but next time use long rectangular magnets designed 2 magnets to each coil, if a north magnet is over the left side of the coil then a south magnet should be on the right side of the coil so that both magnets excite the electrons in the same direction in each coil, when you have a large magnet that covers the whole coil both sides of the coil is seeing the same magnetic pole from that magnet which causes resistance and heat inside the coil, your setup is for an iron core design so if you have 8 coils you should have 16 magnets.
@@harribeydom I have a design idea of my own, that involves heavier windings, more coils ,and magnets on both sides to create the a magnetic flux. It should be able to put out more amperage and perhaps may be efficient...if I get it right.
Hello Dominique, as I can very well imagine that this is the future of e-engines, I have already sent you a message on TH-cam in the past 2-3 days. Did you receive it too? Unfortunately, it is not possible to add pictures to the comments here on TH-cam, so I added the link to my HomePage. The comment with my HomePage is unfortunately no longer visible?! Greetings from Tübingen - Germany
Hello plz i tried to make my generator , i used 12 PCS of neodymium magnet 42*10*4mm and around 500 g of copper but i couldnt have more than 12 v 1 a at 2000 RPM , plz Can you help me to improve the efficiency ?
@@harribeydom Thanks for answering this question, I was wondering the same thing. Is the generator optimized for a particular amount of wind / blade size?
i thing this is slow rotation generator... but 2000rpm is to much ... this is for vertikal turbine not for horizontal... you try horizontal generator ?
Very nice but also very labor intensive compared to planar motors using multi-layer PCBs with etched coils, i.e: th-cam.com/video/yCJ5vstBRdw/w-d-xo.html th-cam.com/video/KSjOWFWtmto/w-d-xo.html I wonder where the performance vs cost sweet spot is for hobby level motors and generators.
finally, somebody who actually uses both sides of the magnets to generate power!
Both cause the flux to flow between with no slowing iron in between !
A better and stronger effect of the magnet is when there is only one stator and a double rotor with magnets
Yeah but that's only because he didn't use a halbach array
@@Kerivity he kind of used the halbach array since he used the small magnets to form a symetric shape as coils
In axial flux they don't use 2 stators because the other side has a weak magnetic side that's why

I could have done everything needed with a drill press alone.
As you said, the R&D is the hard work, the copying is easy.
very neat and clean work. salutes.

Good job my friend
beautiful mind make beautiful thing,,great work ,thank you.
Great work@

Fantastic work. Where can you download the files to print yourself or even better the step files as I’m looking to make a 3d printed wind turbine
it's very useful, you are very good, i want to make one but i don't know how
Very Interesting 👍
Is there any formula to find the required number of turns,Selectio of wire Gauge,Determination of Kw
Same question here
Excellent, Sir
is there a table where you guys looked at the ampacity of your conductor?
Great job 👏
Nice I'm from india friend
Which material use of 3d printing
And what is the width of rotor
2000 rpm 190 watt /7 = 27 v, not too shabby for a 100 rpm

Looking nice
How to calculate winding turn and dimension of motor .
3:45 why so much gap in the center? there can be fited more coil to induce more electron at same RPM.
Where can I get the STL files?
Is there a true life use case for this specific generator or it's just a laboratory demonstration?, anyway it's wonderful!
Gretings, please I'm interested in the project to replicate, if it's possible to get the file or send by shipping to Colombia
muy buen video muy ilustrativo, as intentado replicar el motor rx 18 de Antonio romero?el funcionamiento de ese motor es similar al rx 18
Have you tried using star delta connection windings. In large 3 phase motors this is used to go from initial startup to high speed. Does this work in reverse for generators.
Do sell this? Or do you sell the kits? Layout?
very nice work , is ti possiable to have drawing this one and dron motor with 3d printed winding/ thank you.
How much does it cost to get these 3d printed parts and for making?
How can i get these cad files,love this project.
Cool! How does it work on a wind turbine?

another fail is that he used 1 magnet side instead of two
I have 2 guestions:
Bycause curing thi wire resin?
Bycause the generator is ironless?
Bye Uwe
Nice sleek design utilizing both sides of the magnet. Did you design this yourself and have the 3d printing done at a speciality shop?
Yes the design is from our staff on Laplace and the printing by Initial Prodways
@@harribeydom I have a design idea of my own, that involves heavier windings, more coils ,and magnets on both sides to create the a magnetic flux. It should be able to put out more amperage and perhaps may be efficient...if I get it right.
Hi, thank you for the video and I'm sorry for my ignorance. What's the advantage of not using a steel core? Many thanks in advance.
the advantage is that you don't need machine tools to make them
Does it generate more energy than the motor it used to run ?

Greetings from Tübingen - Germany
Can it be made more efficent to produce higher watts at lower rpm
The video is very good and easy to understand... Can you give me the 3D file, please? thank you
How much difference did the presence or absence of the small magnets make during testing?
Noticable, I'm sure, else they wouldn't have been in the final design.
👀 Kann man im 3D-Drucker hergestellte Teile bestellen????
How to by a kit construktor? Or plastik kit?
great work! are the cad files available somewhere?
how do you use it as brushless motor? can I use it as a stepper or servo motor?
And if the customer doesn’t own their own lathe?
I need 5 asap
Was it a delta connection rather than star connection. Is there a benefit of using delta connection.
no, it's just to adapt the voltage to the MPPT controller
Bonjour 😊, could you share some schmatics, dimensions? Merci 😊
Hi, do you sell these motors. I needed a few customised ones. Or if it is bought, please share the link

Hi sir , what is the shop you bought copper wire is it ?
how did you calculate the number of turns and other parameters?
A phd simulate the complete actuator in 3D with
ansys-maxwell
@@harribeydom yeah well that was easy having your own phd handy :)
@@harribeydom Thanks for answering this question, I was wondering the same thing. Is the generator optimized for a particular amount of wind / blade size?
@@mattmatolcsi6457 the best efficiency is obtained around 2000rpm by multipling the speed of the propeller by 3.
Cuanto cuesta un motor como ése en
Pesos mexicanos
why this motor don't have iron core?
does it mean that the current that comes out is the result of the rpm speed?
yes
Sea for me someone to drop a file on the 3D printer of this generator or where I can buy it. Please
Cute safe things that make electricity.
We could probably wear a bracelet device that would charge our cell phones while we move around during the day?
Where to order these set?
May I how much out put of this alternator.
Man-o-man your work is nice. Any chance you can share the .stl files or are they from a private party?
did you get the files?
@@probando-de-todo no I didn't know that you shared them. Did you send me a link of something?
Can you give me a design please?
Hello! What efficently have this alternator?
I want a making alternator
i thing this is slow rotation generator... but 2000rpm is to much ... this is for vertikal turbine not for horizontal... you try horizontal generator ?
for better efficiency it is better to multiply the speed using pulleys
What is the price of this bldc motor??
Just curious, why no iron?
so that it can be reproduced without a machine tool
Very nice but also very labor intensive compared to planar motors using multi-layer PCBs with etched coils, i.e:
