Structural modeling of small and large induction machines using integral manifolds

Structural dynamics of small and large induction machines are investigated using integral manifolds and are shown to be markedly different. Whereas the dominant behavior in small machines is characterized by a well-known first-order speed model, the corresponding behavior in large machines is characterized by a novel first-order voltage model. Nonlinear simulations and eigenvalue analyses illustrate the validity of the structural models developed.<
