On the reduction of nonlinear electromechanical systems

The present work revisits the reduction of nonlinear dynamics an electromechanical system through a quasi-steady state hypothesis, discussing fundamental aspects this type approach and clarifying some confusing points found in literature. Expressions for characteristic time scales are deduced from physical analysis that establishes analogy between kinetics chemical reaction. It provides justification, supplemented by non-dimensionalization scaling equations, to reduce interest assuming electrical subsystem, eliminating inductive term equation. Numerical experiments help illustrate typical behavior system, boundary layer phenomenon near initial dynamic state, validity limits quasi-steady-state assumption discussed here.
