  1. Great to see this Hugh, I definitely think that making the information available in digital form is the way forward for widening access to this great technology

    • I’ve just bought a copy even though I already own a paper copy just so I can always sleep well at night knowing that I have a copy with me wherever I may be!

    Hi, I’ve received my copy of the “recipe Book” and as I’m aiming for a 12V system ( already have inverter and batteries), I would like to ask you if it is possible to have 9 coils(12 magnets) instead of 6 (as in the book) an also if I shell use the same amount of wire divided by the 9 coils.

    i.e. in the book 6 coils x 130 turns = 780/9 =87 turns

    Right now I’m running 1 magnet plate (12 – 40x20x10 neodymium) and 9 coils x 170 turns 1mm wire and with 3x 600mm alluminium blades I’m squeezing a meere 5 A @ 4 to 500 rpm , what can I do to improve the power output
    thanks
    Francisco

    hi Francisco,

    Yes if you have 12 magnets then 9 coils is a good choice. There is a description of how to calculate the right number of turns per coil on page 54 of the recipe book. If you don’t like the process of calculating then you can use a standard design from the book or use trial and error.

    In your case why not add a second disk on the other side of the stator to increase the flux and reduce the rpm?

    have fun

    Hugh

    Hi there

    I last week I bought your excellent Workshop book and was impressed enough to get a hard copy of your recipe book. However, I bought the 2011 edition off amazon not realising you have an up to date edition available. Is there much difference? What would I be missing? (I hope to be having a go as soon as possible)
    Regards, Paul.
