Few questions about Synchronous generator. A rotor is rotating with angular frequency ω. In this rotor we have windings, which produce magnetic field, through a DC supply. This supply is connected to a rotor with brush contacts. Now this field induces a emf in windings, which are in stator. Few questions: If i connect a load to a stator(generator), current will start to run. This current creates its own changing magnetic field. How come this field doesn't affect the field produced by rotor? Shouldn't we at one point have 0 induced emf? Since 2 fields cancel out. I am probably getting this wrong. And it says here in my book, that the current will lag behind induced emf in stator. Why? Thank you.
