Answer Posted / rakesh kumar
well armauture reaction is the effect of armature flux on
the main field flux , the effect of armature reaction in a
dc machine is cross magnetising that is to distort the main
field flux and if the effect of saturation is taken into
account then it leads to demagnetisation as well. in case
of a dc motor the armature flux the flux at the leading
pole tips are weakened while it is strenghtened at the
trailing pole tips .
