Equivalent-Circuit Extraction for System-Level Modeling of Three-Phase Synchronous Machines - Application Brief

The equivalent-circuit extraction (ECE) method automatically generates an efficient system-level model from a magnetic fi nite element method (FEM) model of a radial-flux three-phase synchronous machine. FEM allows detailed analysis and optimization of the nonlinear time-dependent electromagnetic characteristics of synchronous machines. The ECE method allows the characterization of the nonlinear magnetic characteristics of the machine into a circuit and system simulator, thus permitting optimization of the complete drive system.
