    I have a badly broken (separately core separately wireframe) on this hit is wound primitive and there is no secondary it and I want to wind them :D
    I calculated from a book and I found quite strange in my opinion the results
    if they are wrong, please correct them, it is best that some professional scrolling the opportunity to miscalculate again because they can be beets 8)
    so yes
    diameter of the middle column = 17.6 cm
    I want to get squeezed 200-250 watts of power from the secondary volt 52 volt (2x26v) and I got such numbers :)
    130 rings at 2,5zw / volt with 1.4 mm diameter wire (250 watts: 52v is almost 5 A)
    I'm thin from the mat, so I am asking for help, I can not see whether this result is good or good patterns. I want to the score for the first time in my life and I do not want to it out I was lucky
    and I've always had the right match, I have to rewind :(
    welcome any comments on scrolling :)
    for everything in advance thanks to :)

    PS I remembered how someone would calculate it, give me the patterns that :) used thanks to

    What does it mean "midrange diameter"? If the column is round and 17cm in diameter then you can "pull" 50kW from this trafo. Enter the dimensions of this core.

    I mean, that it is a good match of plates with the shape of letters E and I if we assume that E has 3 columns and one goes through the center of the carcass, looking at the one from above I have the field of this column is not my diameter sorry:? on the perost so IIIIIIIIIIIIIIIII
    III
    III
    III
    AND
    this is the central column looking at E from the side she enters the carcass from the top looking mierymt dimension x and we do multiplication (from the formula to the field of the rectangle) and we have a central column field 17.6 cm square sorki for archaic drawings but for now I can not save anything in gif :D

    firstly if you have the original winding working then you can calculate the number of coils / volt, you simply wind 20-100 turns, no matter what wire you divide this wound amount by the output voltage and you get the number of turns on volt then you multiply it by the voltage you need and you get the number of secondary winding coils (it is good to increase it even by 10% (idle voltage under load decreases)
    and further with regard to the power depending on the cross-section of the middle column of the wire thickness depending on the current consumed, see

    You can also use a program that will calculate the windings for you eg in Download => Polish programs => Calculator transformers. There you will also find other programs for such calculations
