The induced emf developed when the rotating conductors of the armature between the poles of magnet, in a DC motor, cut the magnetic flux, opposes the current flowing through the conductor, when the armature rotates, is called back emf. Its value depends upon the speed of rotation of the armature conductors. In starting, the value of back emf is zero.

Please advise if it is possible to suppress or neutralize the back emf from a permanent magnet ac generator, there are three phases and one neutral wire that come out of it?
Thank you.
