    where exactly on a DC machine are the brushes placed...are they placed along the magnetic neutral (ie perpendicular to the field flux) or along the direct axis(alnog the field flux)

    Hi,

    I asume you are talking about a DC motor. The brushes conduct current to the windings in the armature, and so cause magnetic fields to form that react with the fixed fields in the stator windings. Since the armature rotates, the brush connections to the commutator segments change constantly.

    Hi haditya,

    To elaborate on beenthere's explanation, take a look at the material on electric motors on The HowStuffWorks website..
