Description

Hello,

Here is my wind turbine that is fully printed PLA.

All other parts for assembly are easily found online or in stores.

It is fully functional (it is still in process but I will put my page updated with new photos and comments)

It is to "horizontal axis" therefore the more complex after the generator is the passage of electricity around the vertical axis. The trick is to cut the vertical axis (stainless steel tube) into two parts (connected to the two poles + and -) and fasten them together with a threaded rod in the center with an insulating sheath. Contacts are made with springs that rub on each stainless steel tubes.

It consists of a helix made with simple wooden planks 10mm thick. It is very easy to build and very cheap.

To produce electricity, I printed a generator "axial flux" PLA. It works perfectly, it mainly consists of a copper coil plate (electric power depends on the diameter of the wire used) and two plates of neodymium magnets.

I have a small printer (micro delta) that I use to its limits so usually everyone can print all the files on all other printers. (In case of problems, do not hesitate to contact me to find a solution together)

Propeller and rudder:

The propeller consists of four blades constructed with planks 10mm thick. The government is also made with boards of 10mm diameter. (These parts are in blue on 3D modeling)

Axial flux generator:

The central plateau is made up of 9 coils connected in series star and PLA bonded between two pieces (with an epoxy adhesive).

I used 0.3mm diameter copper 9x 15 meters. This wire diameter provides a good compromise between voltage and current intensity.

The magnet plates are made of neodymium magnets 20mmx10mmx10mm 12 each. They are also attached with an epoxy adhesive.

While the metal is used in stainless steel, except the threaded rods that are brass (to be cheaper).

I "straightens" then the current with two diode bridges connected between the three phases.

I hope I was clear in my explanations, but I can make you diagrams if necessary.

Do not hesitate to contact me directly on my email address ([email protected]) if you need me to help you to build or I send you some items.

Bonjour,

Voici mon eolienne qui est entièrement imprimée en PLA.

Toutes les autres pièces pour l'assemblage se trouvent facilement sur internet ou en magasin.

Elle est complètement fonctionnelle (elle est encore en cours de fabrication mais je mettrai ma page à jour avec des photos et des nouveaux commentaires)

Elle est à "axe horizontal" donc le plus complexe après le générateur est le passage de l'électricité autour de l'axe vertical. L'astuce est de couper l'axe vertical (en tube inox) en deux parties (reliées aux deux poles + et -) et les fixer ensemble avec une tige filetée au centre avec une gaine isolante. Les contacts se font avec des ressorts qui frottent sur chacun des tubes inox.

Elle est constituée d'une helice faite avec de simples planches de bois de 10mm d'épaisseur. Elle est donc très facile à construire et très peu chère.

Pour produire l'électricité, j'ai imprimé un générateur "à flux axial" en PLA. Il fonctionne parfaitement, il est constitué principalement d'un plateau de bobines de cuivres (la puissance électrique dépend du diamètre du fil utilisé) et de deux plateaux d'aimants neodyme.

J'ai une petite imprimante (micro delta) que j'utilise jusqu'à ses limites donc normalement tout le monde peut imprimer tous les fichiers sur toutes les autres imprimantes. (En cas de problèmes, n'hésitez pas à me contacter pour trouver une solution ensemble)

Helice et gouverne:

L'hélice est constituée de quatre pales fabriquées avec des planches de 10mm d'épaisseur. La gouverne est aussi fabriquée avec une planche de 10mm de diamètre. (Ces parties sont en bleu sur la modélisation 3d)

Générateur à flux axial :

Le plateau central est constitué de 9 bobinages montés en série en étoile et collés entre deux pièces de PLA (avec une colle epoxy).

J'ai utilisé du cuivre de 0.3mm de diamètre 9x 15 mètres. Ce diamètre de fil offre un bon compromis entre voltage et intensité du courant.

Les plateaux d'aimants sont constitués de 12 aimants néodyme 20mmx10mmx10mm chacun. Ils sont également fixés avec une colle epoxy.

Tout le métal utilisé est en inox, sauf les tiges filetées qui sont en laiton (pour être moins chères).

Je "redresse" ensuite le courant avec deux ponts de diodes montées entre les trois phases.

J'espère avoir été clair dans mes explications, mais je peux vous faire des schémas si besoin.

N'hésitez pas à me contacter directement sur mon adresse mail ([email protected]) si vous avez besoin que je vous aide à construire ou que je vous envoi certains éléments.
