摘要: The authors present a novel formulation which allows the inclusion of circuit equations in finite element analysis two dimensions. Two types magnetic conductors are considered: massive can develop eddy currents and 'fine wire' without current. Kirchhoff's voltage current have been established for these accordance with equations. Furthermore, integrated into an external electric network. This solution two-dimensional problems all kinds connections between conductors, consist impedances (R, L, C) fed by sinusoidal sources. modeling asynchronous machine squirrel cage (with simulation end rings) is given to illustrate one application formulation. >
