Discuss the stability of an induction machine operating in the generator domain (see Figure 38.14)

For example, suppose more power from the prime mover causes the slip speed to increase. How does the torque on the rotor due to its interaction with the stator magnetic field change? Contrast this with the situation when the generator is in the over speed condition.
