Kings River 4.2m wind turbine building workshop Kilkenny

A nice photo gallery by Eirbyte of the recent workshop course in Kilkenny where they built a 4.2 metre diameter turbine.

Clever way to anchor the coils while connecting the tails.

    Can you, or anyone ???? tell me which is the absolute correct way to connect the coils please.
    On many diagrams i see all the coils connected in a clockwise connection, and recently i see that it was very important to … connect the first coil – clockwise, the next coil – anti-clockwise, and the 3rd coil clockwise … and so on.
    maybe both methods are correct in some stators, can you settle this for me please.
    Thanks

      hi Derek,

      The correct way depends on a few things so it’s not a simple answer and the safe thing is to follow the instructions for the design. Actually clockwise and anticlockwise do not matter but you need to make them all the same. Or in a few cases you do have to reverse the connections as you move around. For example with single phase where the coils and magnets are equal numbers (for example 8 magnets and 8 coils) then you do have to change the direction for the even number coils as you describe.

      Most people use my method of 3 coils to 4 magnets, and in that case you do not have to change the direction and it must be the same on every coil. All clockwise or all anti clockwise. This gives a 3-phase output.

      best, Hugh
