  1. Antonio, 9 coils and 9 magnets are possible for a single phase generator,
    for a 3 phase generator the ratio is 9 coils and 12 magnets.
    The polarity must be “N” and “S” facing to have the most attraction to each
    other, that means that the magnetic Flux is greater when it passes the coils

  3. Is the a drawen pics in inches ?How big everything is like wirer ga.#of
    turns on coils outside of stater coils.would like to copy this if you had
    some measerment s of this

  4. hi sam im Antonio Olivera can i do 9 coils 9 magnets dual magnets core
    with opposite poles facing each other

  7. Good video on how not to build a stator. The main problem with this design
    (that is available all over the web) is that the N and S poles need to be
    over a same coil at the same time to achieve maximum power output. That
    never happens with this design. Ideally you need a coil for each pair of
    magnets – not just fill the space in the stator.

  8. the black, yellow and the green wire…where they go connected ?

  9. I am not sure what you are asking me…

  10. Might I ask why the windings are not uniformly spaced?

  11. @TheEm991, the 3 phase, black, yellow and green go to a bridge rectifier to
    convert it from Ac to dc.

  12. hi Sam !! … question ! … viewing it like that ¿what’s the direction of
    the windings? i mean ¿clockwise or counter-clockwise?

  13. @ronalduriolcabrera, if you are starting on the inside, then it is
    counter-clockwise for each coil. sam

  14. This design is right. It is designed to avoid cog. When one magnet is
    producing max current then the next is about to enter the coil and the 3rd
    magnet is about to leave the coil.This makes the resisting torque smooth.
    if you put the same number of magnets as the number of coils then cog it
    huge and it is not a good design.

  16. hello emagnets.
    I one of the replies at fieldlines discussions u said that two magnets
    above opposite coillegs would cancel each other in voltage. here in your
    annimation it is more or less like that… I am building the hugh piggotts
    3meter axialflux alternator. in his book the coilleg with is 30 mm, same as
    magnetwidth… I made it as in the book; 55 turns 2@1,7 mm.. magnet width
    is 30 mm (and coillegwidth is also 30 mm-) … as i see it two magnets will
    at some times be over one coil. same as in ur annimation. can that be a
