Answer / abhidewas

ideally both MNA GNA should coincide. if they are interchanged then sparking at the brushes may happen. also because of armature reaction terminal voltage may decreased.

Answer / kalidass

There is voltage drop due to armature reaction may happen

Answer / suburavichandran

There will be a very high loss due to increased armature reaction. sometime the motor may become stand still.
