Abstract

The analysis of electromechancial transducers using magnetic drive requires multidomain analysis that includes at least the electrical, magnetic, mechanical domains. Such a system results in a set of differential and algebraic equations (DAE) that can be solved by analogy using modern electrical circuit analysis codes, or with codes written specifically for multidomain DAE modelling. Often, some components in the system require partial differential equations for their analysis, and FEA methods are required. This is especially true in magnetic systems where the flux path including leakage defies simple a priori estimation. The examples of a variable reluctance device is shown.
