Abstract :
The phenomenon of self excitation in induction machines is examined and a physical interpretation of how self excitation occurs is presented. The important parameters are shown to be the shaft speed, the residual magnetism, the reduced permeability at low magnetisation, and the size of the capacitor connected to the machine. The results are important in applications where induction machines are used as stand-alone generators for a power system, as the reliability of self excitation in such cases must be very high.
