photos of workshop course Scoraig April 2013

date: 20-27 APRIL

Location: Scoraig

4 participants built a 2 metre ferrite turbine (2F) for 24-v battery charging.  Also balanced and fitted some 3 metre blades to last year’s 3 metre ferrite turbine.

Photo sequence is a bit random sorry.


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.

    Hi Hugh! I ave experience with used magnet from magnetron ex microwaye-oven ?
    existing method for calculate proiect? Wat it’s grade level of the flux for this anular magnets?
    thank you.

    Hi Hugh,

    What’s the expected power output for this 2F Turbine?
    How about 50x50x15 C5 Magnets? Big difference acompared with this ones?

      hi Pedro,

      I have had one of this design running all winter and we did some datalogging on it to measure the performance. I would rate it as a 400 watt machine. Sometimes the power output will surge to about twice this much but the maximum sustained/average output is about 400 watts.

      You could use 15mm thick magnets yes but it would run a bit fast. You’d have to reduce the air gap to a much closer clearance. You’d probably get acceptable performance with the same stator but I’d be inclined to use more turns of thinner wire for the best output in low winds. And then the maximum output would be lower and the tail would need to be a little bit lighter too.
