In a few days will be uploading videos and photos of the mechanical changes necessary for the wind turbine, will advance while the main things:
1) The generator must be perfectly aligned with the crankshaft (we have replaced the crankshaft with a exactly diameter (3 mm) and perfectly straight rod
2) the supports of the generator have been reversed so that the window-holes make it possible to precisely align the motor-generator shaft
3) the joint between generator shaft and propeller shaft were made on a lathe
4) we think to fix the propeller blades with small screws so that we can adjust the angle of incidence
5) we are thinking about how to achieve an efficient pivot for the rotation of the entire wind turbine, the problem is to ensure both: the rotation, and the electrical contact, we think it is better to prevented by a stop block the 360° rotation, so that electrical contact can be done with simple flexible wires
Then we will pass the first test in a wind tunnel ... ;-)
P.S. my English is almost perfect if you do not understand something is a google blame

Hi everybody,
ReplyDeleteWe have already fixed the vertical axis of the wind turbine on a ball bearing.
We then realized that there was going to be a problem : the wires of the datalogger will roll-up around the pole. We may have found a solution but I have to verify with our technician.
I shall give you more news in a few day.
Ciao
Emilie
PS: we would prefer not to block the 360° rotation in order not to miss some wind!
the same in french :
Nous avons déjà fixé l'axe de rotation verticale de l'éolienne sur un roulement à bille.
Nous avons ensuite réalisé qu'il allait y avoir un problème d'enroulement des câbles de l'appareil de mesure. Nous pensons avoir trouvé une solution mais je dois vérifier auprès de notre technicien.
Plus de détails d'ici quelques jours.
Hi Emile, it's the same problem we have (point n.5) when you have a solution please let us know.
