Armature reaction is the interaction between flux set-up by the current carrying armature conductors with the main field flux.The entire energy conversions from mechanical to electrical in the case of generator, and electrical to mechanical in the case of motors takes place only due to this interaction.

by what factor the starting current is used when comparing star and delta connection for motor starting?
