thanks, what a great project! i wondered if performance might be improved by capping the outside of each stator with a magnetically permeable material such as soft iron, to more easily complete the magnetic circuit (because air and plastic don't provide magnetic shielding and do not efficiently close the magnetic loops outside the motor)?
Gallium (or mercury or perhaps a ferrofluid) moving at really high speeds due to MHD might also create an interesting effect, apart from magenetic or electric fields......
hai Dominique, i am developing a control circuit for tubular linear motor which looks exactly same as yours . i need to contact you for further guidance, so can you please provide your mail id or any contact details
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
Hello Dominique, as I can very well imagine that this is the future of e-engines, I have already sent you a message on RU-vid in the past 2-3 days. Did you receive it too? Unfortunately, it is not possible to add pictures to the comments here on RU-vid, so I added the link to my HomePage. The comment with my HomePage is unfortunately no longer visible?! Greetings from Tübingen - Germany
Bonjour M. Harribey, quel est le matériaux utilisé pour les bobines? Je suis étudiant en M2 de Chimie et j'aimerais reproduire votre moteur, auriez vous quelques pistes? je peux comprendre si certaines choses sont confidentielle
C'est imprimé en 3d en aluminium mais pour l'instant c'est encore très cher! D'autres moteurs sur ma chaîne sont plus facilement reproductibles et surtout moins onéreux. Bon courage
Love this. Have you considered doing some print-in-place things with the magnets? you might be able to reduce assembly by paising the print, placing the magnets, then continuing the print. This is one example: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rk6MkW1eRiY.html
Imagine putting a high efficiency Tesla Turbine in-line with a high efficiency axial flux... generator? assuming we ever obtain the material strengths required, 😅
I think a 3d printed generator would be more efficient 🤔 since it would have less drag/energy loss than iron with magnets. Or steel 🙂 as long as you have good bearings??? It should be reliable? Right? Should be.
Why do you tubers make all these beautiful DIY generators without bothering to wind the coils around a soft iron core? These generators would be far more powerful if they made use of soft iron cores, which provides low reluctance and high permeability to the magnetic flux and would greatly increase the magnetic field strength and thus power output. I stand to be corrected but I have yet to see a factory made alternator or generator that doesn't wind the coils around a soft laminate iron core, whether the magnetic flux is axial or radial. If soft iron cores are not necessary, then why do manufacturers go to the expense of using them in generators and transformers and not just leave the magnetic flux to find its own way through the air?
I believe that this design aims toward the fact the small turbines might not have enough torque to spin the dynamo if it had an iron core since the magnets would be attracted to it making it difficult to rotate the core, so It aims more on lowering magnetic friction than power output.... could be wrong, but, I believe that this aims to minimize magnetic friction.
Yep, cogging due to iron core would not allow most turbines to start up in low wind speeds and axial flux generators with opposing sets of magnets keep the flux directly in the path of the coils. This radial flux model doesn't work as good as the axial flux variety
Really nice build. So many questions. Air coils no ferrite or iron core? I'm wondering the purpose of the carbon winding on the rotor? You are in a lab environment, what about an easy DIY fuel cell, for hydrogen, perhaps a pem or sofc?
One suggestion please, to improve efficiency one thinner magnet if kept behind each coil might be fruitful, i think one further trial is needed ??????? Though the effort you used is quite appealing and inspirational, thanks.
