“…Extending the Fourier modeling with mode-matching, regions (i.e. material blocks) with a different width can be incorporated [9,17]. Unfortunately, an additional physically non-existing boundary is necessary to obtain a solution.…”

This paper presents a hybrid analytical modeling method which integrates a mesh-based magnetic equivalent circuit model with the Fourier modeling approach. This hybrid analytical modeling is capable of correctly predicting the electromagnetic field distributions for various two-dimensional geometries. The generalized approach of the presented hybrid modeling concept, makes the modeling technique applicable to a wide range of electromagnetic devices. By only meshing the parts of the domain in the vicinity of the high permeable materials, the increase in computational effort is limited compared to the sole use of Fourier modeling. The proposed hybrid analytical modeling method predicts the force in the geometry with ≥ 97 [%] accuracy with respect to finite element analysis.

“…Assuming an infinitesimally small piece of infinite permeable material between the shield and the air next to it, the z-component of the magnetic flux density is assumed to be zero on these edges. Due to the large difference in permeability of the shield and the air, the errors introduced by the assumed infinite permeable pieces are very limited [11].…”

“…In each region, the general description based on a summation of N harmonics (the fundamental and its higher order harmonics) gives the magnetic flux density according to the equations given in [11]. The application of this general description in the regions results in a boundary value problem, which is solved by applying boundary conditions on the interfaces between the regions.…”

This paper compares force measurements on a shielded coreless linear permanent magnet motor with 2-D models. A 2-D semianalytical modeling method is applied, which is based on Fourier modeling and includes force calculations. The semianalytical modeling correctly predicts the behavior found in the measurements, disregarding the saturation effects in the shield. The proposed semianalytical modeling method gives a good preliminary indication of the forces, which makes it a valuable modeling technique during design.
