Photos of the Scoraig wind turbine building workshop

Last minute adjustments

Participants: 6 (Robert, Jonathan, Kostas, Benji, Yanti and Kern)

Dates: 5-12 May 2012  Location: Scoraig.

Project: 3 metre machine using ferrite/ceramic magnets at 24VDC

Poles: 10, (3 magnet blocks 50 x 50 x 20 per pole)

Coils: 12 (37 turns of 2 x 1.6mm wire)

Target cut in speed (recipe) 170 rpm

Application – the croft next door to me (for sale) on Scoraig.  24V system and 20 metre tower with dead Samrey prototype on it.

Accommodation the bunkhouse, Scoraig.  Full-on home made food and frivolity.

The following video shows Jonathan helping me to put Paul’s (green painted) blades onto the zebra turbine.  We also increased the air gap a little to make sure the magnets did not rub on the stator.  The cut in speed is a bit higher than I would normally choose for a 3 metre turbine (195 rpm for 24VDC) but it runs very smoothly, and will definitely not stall at least.

About hugh

I live off-grid in NW Scotland and have spent my life playing with wind turbines. I also love small hydros. Hands on renewable energy is my thing and I like to learn and to share my experiences.

    nice project..enjoyed it..greetings to all team members..with love from India. This project has great potential in India.

    Have you ever thought of conducting a course somewhere in Africa? Eg South Africa to cover the Southern African countries. Food for thought

    Hello Hugh,

    Thanks for your really nice stuff, I would like to do a ferrite machine using 2” X 2” X ¾” is this possible using a similar arrangement like what you have done on 3 meter machine?
    Please assit.

      Hi Mpennzi,

      Yes I would say you could use 2″ x 2″ x 3/4 as they are about the same size as the ones we used in the story above.


  4. Hi Hugh,
    thank you for this really nice time!!
    I’ve got so much experience for my live, not just for windturbines!!!!

    We are the SCORAIG CREW 2012!!!!!

      Wow Jonathan, it really looks liek you had the TIME OF YOUR LIFE! I am so glad you enjoyed the wind turbines as much as the what seems, fantastic company!

    I am sorry Hugh,

    thanks for the clarification admin,

    great to read this article, from one of the images “up she goes”, i can see the turbine is placed well below the tree height, what is the max watt it produced? just curious admin

    • admin says:

      The tower is 20 metres but the trees are at least 15 metres so it is only just high enough to see some wind and it would be better a bit higher. It could easily produce 1000 watts peak, but the zebra is a bit light so it furls at about 600 watts. I like that with a prototype. I can always add more weight if we need to.

    Hi Hugh,
    Just wanted to thank you again for an educational and fun week. I’ve got all kinds of ideas about attempting a build on my own. I’ll have visions of zebra tailed wind turbines spinning in my mind for years. I thoroughly enjoyed the whole Scoraig experience.

    Hi Hugh,
    very nice workshop, this ferrite wind generator looks great,
