Transformer rewind ques

    Hi

    Instead of using two MOT's with secondaries in parallel could one cut
    both I's off and join the two E's together (and leave both primaries
    on - in phase of course ) and then add a thicker single secondary
    winding ? Would it be less efficient than two separate ones ?

    <Thanks/>

    For the same current in the same windings (i.e., primaries and
    secondaries in parallel, phase correct), the transformer would see the
    same flux and therefore you could connect it "butt to butt" just fine,
    as far as I can see.

    You can rewind if you want, but the usual purpose of having MOTs is to
    keep at least one winding (usually the primary).

    If you're rewinding everything, a much more traditional solution is
    stacking the E's and I's up.

    Thanks for the reply -I mean to leave both primaries on (center of one
    E) and use a heavy secondary winding on the other E.

    By joining the E's together I mean face to face so it becomes a larger
    transformer if you will. Hope this asci art comes out OK.

    Do you mean one transformer on top of the other ?
