    Hello guys,

    long time ago!

    I was looking at the types of armature winding of a DC motor and something confused.
    Link: https://books.google.be/books?id=CglbiM665RIC&pg=SA1-PA24&lpg=SA1-PA24&dq=lap winding in dc machine&source=bl&ots=wKGHqJVc9D&sig=xJWJPmPpAc3V7PxTfLyxyDLtWA0&hl=nl&sa=X&ei=zRGjVMK6GofgatL4gPAN&ved=0CCMQ6AEwATgU#v=onepage&q&f=false

    Page 1-29 and 1-30.

    I added the pictures in the attachment.

    Someone has an idea why the connection of the conductors of the development diagram and the image below doesn't match?

    e.g. commutator segment 4 goes to conductor 7 and 12 at the fig 1.27 while
    for fig 1.28 it goes to 6 and 12.

    Commutator segment 1 goes to conductor 1 and 6 at the fig 1.27 while for fig 1.28 it goes to 1 and 7.

    I assume the fig 1.27 and fig 1.28 are related to each other in terms of connections of the conductors and commutator segments.

    Thanks a lot in advance guys.

    Happy NYE!
