“…Kwon et al used two simplified nonlinear magnetic equivalent circuit models to analyze the magnetic field capability caused by the change in design parameters of the new soft magnetic composite prototype as compared with the basic model prototype [12]. In [13], a multi-objective optimization design for a non-core PM synchronous motor was introduced. By solving two Laplace equations, both the 3D performance analysis and the magnetic field distribution were obtained under open circuit conditions.…”

In order to study the multiple restricted factors and parameters of the eddy current loss of generator end structures, both the multi-layer perceptron (MLP) and support vector regression (SVR) are used to study and predict the mechanism of the synergistic effect of metal shield conductivity, relative permeability of clamping plates and structural characteristics of eddy current losses. Based on the eddy current losses of generator end structures under different metal shielding thicknesses and electromagnetic properties, the calculation accuracy of the MLP and SVR is compared. The prediction method gives an effective means for the complex design of the end region of the generator, which reduces the effort of the designers. It also promotes the design efficiency of the electrical generator.

“…Compared with the traditional way to realize linear motion, such as combination of the rotating motor and rack-pinion or ball-screw, PMSLMs have advantages of direct drive, low loss, excellent dynamic response, simple structure, and so on [1]- [7]. Due to these characteristics aforementioned, PMLSMs can find more applications with requirements of high efficiency, fast response, high accuracy, small volume, etc.…”

Permanent magnet linear synchronous motor (PMLSM) has the advantages of high thrust density and good control accuracy, which can be applied in high-power and high-speed occasions. In this paper, the analytical models are established to obtain the electromagnetic performance for the PMLSMs with dual secondaries and dual primaries. The air-gap flux density and the electromagnetic thrust are also obtained by the finite element model to verify theoretical analysis. Besides, an improved structure is also put forward in order to suppress the thrust fluctuation of the PMLSM. Finally, the advantages and disadvantages of two PMLSMs topologies are listed. These analyses would provide a guide for the design of PMLSMs applied in high-power and high-speed occasions. Index Terms-Bilateral permanent magnet linear synchronous motor (BPMLSM), analytical method, finite element algorithm (FEA), electromagnetic performance.

“…In this paper, we adopted FRM for the analysis and design of the LTPMM. The LTPMM is structurally accompanied by a longitudinal end effect, which distorts the magnetic flux distribution in the air-gap [16], [17]. This effect can be further increased because the electromagnetic active suspension has a shorter stroke.…”

This paper considers a linear tubular permanent magnet motor (LTPMM) for an active suspension system. The LTPMM has an end effect due to its structure. This can be an important factor for analysis and design of the LTPMM because it distorts the air-gap magnetic flux distribution. The field reconstruction method (FRM) was developed for an effective evaluation of the magnetic field in the electric machine. It can reduce the computation time using the basis-function which reconstructs the air-gap magnetic flux distribution with a static finite element analysis. In this paper, we adopted the FRM to evaluate the LTPMM. However, the FRM has been applied only to the rotating machines and does not take into account the distortion of the magnetic flux distribution in the LTPMM. To deal with this problem, we proposed an enhanced FRM with new basis-function. The proposed method is verified by comparing between experiment result, conventional and enhanced FRM. INDEX TERMS Active suspension system, linear active suspension, linear permanent magnet motor, field reconstruction method.
