Main Question or Discussion Point
In a 3-phase induction motor, rotor current demagnetizes the air gap and hence, stator draws more current (to keep the flux constant), which is the reflection of rotor current. This is like a rotating transformer which consumes active power. An induction generator on the other hand, supplies active power to the grid. So, the stator current will be composed of magnetizing current (same as in motor operation) and an active current. My question is, what will be the nature of rotor mmf? Magnetizing or demagnetizing? Since the generator is supplying active power, will the rotor mmf be magnetizing? Is it consistent with Lenz's law?
