What polarity do interpoles take in a DC generator?
- The same as the next main pole behind in the direction of rotation.
- Either, providing they lay on M.N.A.
- The same as the next main pole ahead in the direction of rotation.

Help!? I thought Interpoles in a generator are same polarity as main pole ahead of it? Behind for motors?

I agree with you. This answer is wrong. Since in generators the MNA rotates in the direction of armature rotation interpoles polarity should be the same as the next main pole AHEAD in the direction of rotation! Please check this
