    Are you sure you have the correct words? I've never heard "reentrant" used in the context of a motor. I've only heard it used in the context of multiple tasks executing the same code, but with different data frames.

    degree of re-entrant of an armature winding :

    it says in an article a winding is a single re-entrant if tracing through it once, all armature conductors are included on returning to the starting point.

    how it is 'tracing'? what is the path of tracing?

    You follow the wire from one terminal to another as if you were Maxwell's demon. If you cover all of the wire then the winding is single re-entrant.

    Hoophoop I think they're just explaining how armature winding is like a single conductor with multiple taps (to commutator strips) but Plz try to get a better translation of your question so we can give better help:cool:

    Papabravo Has Maxwell's demon forsaken thermal dynamics for electric motors:eek:? Say it isn't so:(!

    HoopHoop So this post stays on topic and so I'm not causing confusion by joking I think @Papabravo is just saying to run through it in your mind:)

    I could have used Uncle "Traveling" Matt if fraggles were small enough. I'm not sure we ever got clarity on that point.

    Maybe we did -- 18 inches is a bit large for a demon traversing the windings of a motor.

    I didnt want to know who is tracing ... i wanted to know the path in the winding that is to be traced.

    in an armature winding there are several coils. So if I have to trace what is the path to be taken?

    You follow the wire from one terminal to another terminal, then ask yourself: "how much of the total amount of wire did I encounter".

    @HoopHoop

    FWIW: If you are indeed referring to the armature of a contact (i.e. 'brush') - commutated electric motor - then I believe the arrangement will be as per post #5 -- To wit: Tracing as per posts #4 & #10 will involve 100% of the winding:)

    That said -- I'm no expert on electric motors:oops:

    Can you quote the source of the article and if possible a reproduction?

    You're the one that keeps asking the same question expecting a different answer. <snip>

    Now listen, Papabravo is a very smart guy and he is saying exactly what I would say.
    You have been asked for a reference to where you found this idea and you did not help.

    If you have to, "trace" then you look at the wire. The path of the wire is what you, "trace". "Trace" is to become aware of the places where the physical wire exists. The sum of all these places is the path. Tracing is a mental exercise, not a physical activity. You don't move the wire to trace it. You merely become aware of its path.

    I can't imagine that your comment will improve your chances of getting what you want. I hope that you are happy and proud of your conduct.

    I've been reading a lot of the OLD textbooks and subject tomes available via google.books.con

    Re-entrant is/was a term of the art in all of them.

    Ya know... We can all understand frustration owed a language barrier - abuse of those patiently attempting to assist you, however, is quite another matter!:rolleyes: --- A bit less 'tude perhaps?

    Hopefully

    Aye! Audel's agrees!:cool: - IMHO, however, the 'trouble' is vested less in terminology than in the TS's 'deafness' to any assertion falling outside the scope of his preconceptions:rolleyes::rolleyes::rolleyes:
