Our teacher at N7 showed us this as a technology demonstrator. We enjoyed it. Thanks for the effort

finally, somebody who actually uses both sides of the magnets to generate power!

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..

Air core says it all. good workmanship.

Nice! Old technology(lathe work) meets new technology(3D printed parts). Love it.

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.

Very professional! 190W is impressive

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%

very neat and clean work. salutes.

大変分かり易いビデオを有り難うございました。

This man is an artist..

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

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

beautiful mind make beautiful thing,,great work ,thank you.

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.

Great job 👏

Is there a true life use case for this specific generator or it's just a laboratory demonstration?, anyway it's wonderful!

Good job my friend

I would have enjoyed hearing how you sized the wire coils in relation to the magnets. I understand the magnets have to have a certain tapered shape because of the radial “spokes” they have to fill, but how did you determine the mayor and minor widths of the coils and the number of wraps in each coil.

Excellent, Sir

Very Interesting 👍

Cool! How does it work on a wind turbine?

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.

Great work@

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

great work! are the cad files available somewhere?

Does it generate more energy than the motor it used to run ?

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

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.

Do sell this? Or do you sell the kits? Layout?

it's very useful, you are very good, i want to make one but i don't know how

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.

is there a table where you guys looked at the ampacity of your conductor?

how do you use it as brushless motor? can I use it as a stepper or servo motor?

Can it be made more efficent to produce higher watts at lower rpm

very nice work , is ti possiable to have drawing this one and dron motor with 3d printed winding/ thank you.

Looking nice

Are printed generator kits available ? Where and how much ?

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.

How much does it cost to get these 3d printed parts and for making?

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.

2:59 that is nice widing. I dont know why manufacturer dont put more precise in widing motors.

Nice sleek design utilizing both sides of the magnet. Did you design this yourself and have the 3d printing done at a speciality shop?

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....

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

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 can i get these cad files,love this project.

How much difference did the presence or absence of the small magnets make during testing?

👀 Kann man im 3D-Drucker hergestellte Teile bestellen????

Nice I'm from india friend

The video is very good and easy to understand... Can you give me the 3D file, please? thank you

How to by a kit construktor? Or plastik kit?

3:45 why so much gap in the center? there can be fited more coil to induce more electron at same RPM.

Was it a delta connection rather than star connection. Is there a benefit of using delta connection.

Where can I get the STL files?

May I how much out put of this alternator.

Where to order these set?

Is there any formula to find the required number of turns,Selectio of wire Gauge,Determination of Kw

2000 rpm 190 watt /7 = 27 v, not too shabby for a 100 rpm

And if the customer doesn’t own their own lathe?

I have 2 guestions: Bycause curing thi wire resin? Bycause the generator is ironless? Bye Uwe

does it mean that the current that comes out is the result of the rpm speed?

Just wondering why Delta vs Wye?

Gretings, please I'm interested in the project to replicate, if it's possible to get the file or send by shipping to Colombia

great work can you share the drawings so i can make one aswell

What is the price of this bldc motor??

why this motor don't have iron core?

respect...

Man-o-man your work is nice. Any chance you can share the .stl files or are they from a private party?

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 ?

Do you sell this?

Sea for me someone to drop a file on the 3D printer of this generator or where I can buy it. Please

I need 5 asap

Hello! What efficently have this alternator?

Hello Dominique, as I can very well imagine that this is the future of e-engines, I have already sent you a message on KZfaq in the past 2-3 days. Did you receive it too? Unfortunately, it is not possible to add pictures to the comments here on KZfaq, so I added the link to my HomePage. The comment with my HomePage is unfortunately no longer visible?! Greetings from Tübingen - Germany

❤️

I want a making alternator

10:13 21V 8A 178W at 2000rpm with load

how did you calculate the number of turns and other parameters?

Where can I buy this set of motors. Is there an address or gmail?

Just curious, why no iron?

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.

😊👍

Bonjour 😊, could you share some schmatics, dimensions? Merci 😊

😍🥰🤩👌👍👏🙏

Hi Dominique, how can i contact you ? I have something very interesting and i'm looking to partner up. kind regards.

Cute safe things that make electricity.

💪😁

if death had music it would be these tracks : (

Can you please provide stl 1:13 files voltage and power output

Cuanto cuesta un motor como ése en Pesos mexicanos

Very nice but also very labor intensive compared to planar motors using multi-layer PCBs with etched coils, i.e: kzfaq.info/get/bejne/r6l6aNmk2ai2lKs.html kzfaq.info/get/bejne/gbmagrp3vNrRpKM.html I wonder where the performance vs cost sweet spot is for hobby level motors and generators.

🔗 to purchase 😊

Can you give me a design please?

Cool! Can i get the 3d files?

Can you please send me a copy of 3D print file please, Thank you.

Hi, can you please share .Stl files ? Please upload a link in description.

Brother :)
