WARNING: The theoretical maximum power of this turbine is 50watt however, the stepper motor used as a generator has low efficiency with measured maximum power around 20watt. Please try different generators on this turbine and share your results with the others!

This fully functional wind turbine has been specifically design to be manufactured, assembled and operated at home with its unique 3d printable design.

The turbine is optimised to produce a peak power output of 50 Watt and start with windspeed as low as 5m/s making it ideal for domestic applications and battery charging.

The turbine has been designed with a unique Passive Variable Pitch (PVP) design. The PVP maintains an optimum power output through control of the turbines rotational speed. Whilst optimising power output the PVP also protects the turbine from dangerous over speed conditions by limiting its maximum revolutions per minute in wind speeds greater than the design point.

The turbine has been designed with flexibility and growth in mind with provisioning for a bigger generator and blade without alteration to the turbine architecture and major structural components generating more power for less investment in the future.

The turbine components have been designed for Additive Layer Manufacturing (ALM) methods using PLA plastic and 95% of the components require no post processing as these parts do not require ‘print supports’ reducing material usage whilst improving the overall finish of the part. The turbines printed parts can be manufactured using less than 100 meters of plastic making the cost per watt of power extremely competitive.

This is an awesome design! I feel like I am missing something, the parts list doesn't seem to have part numbers that can actually be ordered for all of the mechanical parts? I see the NEMA motor and some of the electronics in the Assembly Drawings but not things like the bearings and slip rings.

Hello, single piece blade added to the files.

Thanks Dan

Hello Daniel,

Is it possible to get the inventor models for the parts where you use the printed bearing sleeves (red parts in your drawings) i would like to adjust your design so that you can place standard regular bal bearings in stead of the printed parts.

Very nice design. Does a single blade design exist, because I can print up to 500 mm height.

Any chance you'll be making an instruction manual like you did for the MkI and MkII? I found it really useful to have all the documentation together.

Hey Dmitry Evdokimov,

Sorry about that, i've upload the PDF versions hopefully they are better?

Cheers Dan

Quantyti list and printing settings lists are very poor quality... Cant see anything if i print it on A4 sheet

Yes! Yes! Yes! Thanks!
