A more general formulation of two-dimensional (2-D) transient finite element method (FEM) for the computation of magnetic field and electric circuit coupled problems is presented. The concept of windings is extended to include groups of solid conductors. All excitations, including stranded windings, solid conductors, are regarded as special cases of the basic winding. The formulation also includes...
Fault current limiter based on permanent magnet biased saturation (PMFCL) is believed to foresee considerable application potentials in power systems due to its obvious advantages both technically and economically. In this paper, a new equivalent model of the PMFCL is presented based on a coupled field-circuit modeling methodology. Firstly, the governing equations of the PMFCL are obtained based on...
Permanent magnet synchronous machines (PMSM) are used in x-by-wire systems, because of the high efficiency and its good dynamic properties. To investigate the performance of the machine at fault situations, a 3-phase, 16-pole prototype (rated state torque 1.7 Nm, overload torque 20 Nm for impulse torque actuation) with tooth coils was built with the possibility for measuring different kinds of winding...
