Texto completoResumen
Transformers have attracted great interest since they have been used due to their robustness and application in power systems. Therefore, the nominal values of transformers grow even more in larger power systems due to the constantly increasing power demand. Many types of research are carried out to increase the performance characteristics of transformers and their compatibility with power systems. There are different methods and analysis tools for these studies. One of them is ANSYS@Maxwell, which performs analysis based on the Finite Element Method (FEM). With this program, the design, modeling, analysis, and performance evaluation of the transformer in a high-performance simulation environment can be achieved through effective strategic modeling. In this study, the design and modeling of a three-phase core-type transformer with coils and terminals are explained in detail in ANSYS @ Maxwell simulation platform. Besides, the transformer models examined were adapted using ANSYS@MAXWELL software based on the finite element method. Analyzes are performed to estimate the core-losses, leak-losses, DC-losses, and winding-eddy current losses-of transformers with this program. A large number of meshes were used in FEM analysis of 2D and 3D models to examine the losses in detail.

A novel winding type permanent magnet coupling (WTPMC) is proposed to work as an adjustable speed drive with slip power recovery function. As a kind of dual-mechanical-port electric machine with radial-flux configuration, the WTPMC consists of an outer rotor embedded with three-phase windings, an inner rotor populated with permanent magnets, and a slip power recovery circuit comprising a rectifier, a boost converter, and an ultracapacitor. The working principle of the WTPMC is presented, and its mathematical model is derived. To develop a WTPMC prototype for automotive applications, two-dimensional (2D) finite element analysis (FEA) is conducted using Ansoft Maxwell software to study the steady-state (constant slip speed) performance. For the experimental validation, the WTPMC prototype is manufactured and tested on a test bench. To show the accuracy of the 2D FEA, the computed results are compared with those obtained from experimental measurements. It is shown that the agreement between the 2D FEA and experimental results is good. Moreover, the WTPMC prototype can operate in the output speed range under different load torque conditions. The slip power recovery efficiency for the 2D FEA is 66.7%, while, for experimental measurements, it is 57.2%.

Abstract In the paper, methodologies for the magnetic field simulation in an axial flux permanent magnet coreless (AFPMC) motor have been proposed and discussed. Two approaches have been considered and investigated, both based on representing the 3D field distribution by superimposing axisymmetric 2D patterns. The first of studied approaches applies directly to the Biot-Savart law while the second uses a 2D axisymmetric finite element method. The selected results of magnetic field distributions and electromagnetic torque characteristics for the considered AFPMC motor have been presented and compared with results obtained using the commercial FEM package ‘Maxwell’. The elaborated algorithms have been incorporated into the design routines allowing multi-parameter optimisation of the considered motor construction.

The development of generative design technologies that solve the problems of structural optimization and digital twins, that is simulation models of devices with at least 95 % accuracy, is an urgent task. These tech-nologies are usually implemented on the basis of 3D models of physical fields, for example, using ANSYS Maxwell or COMSOL Multiphysics packages, which are demanding in terms of computer resources and de-signer skills. However, the sufficient accuracy for transformer digital twins can be achieved using chain and 2D field models. The article aims to develop the models to calculate the transformer with the accuracy and ability to take into account the design features of a particular device, which is characteristic of digital twins. This can be used in generative design of transformers and in the study of their operation modes. The finite element method implemented via the authoring EMLib library which allows calculating magnetic fields in a 2D formulation was used. The simulation methods using the MatLab Simulink SymPowerSystem package were also employed. The assumptions made during the power transformer simulation have been estimated. They include the possibility of using chain and 2D field models without taking into account the steel anisotropy with Dirichlet boundary conditions when calculating the scattering fluxes. 2D field models have been developed for calculating the main flux and scattering fluxes, which are able to form the basis for digital twin technology and generative design of transformers. A simulation model of a transformer implemented in MatLab Simulink has been provided. The possibility of using the models for diagnosing transformer faults has been demonstrated. The simulation results of a transformer with a defect have been presented. The results obtained can be used in the development of transformers to search for optimal designs and to study the results of design decisions without creating prototypes. The findings can also be applied while operating the transformers to assess the damage and failures without dismantling and according to the test results.

In order to obtain good starting performance of the electric scooter driven by brushless permanent-magnet direct circuit motor(BLPMDCM)，modules of RMxprt and Maxwell 2D in Ansoft software are used to build finite element simulation model of BLPMDCM. We simulated and studied the basic features and starting process of BLPMDCM. The results of internal magnetic field distribution and dynamic performance simulation are obtained when the motors are in different positions. The results provide a theoretical basis to further optimize the design, improve the starting torque and reduce torque ripple for this new type of permanent magnet motor and its control system.

Linear generators are one of the most efficient sea wave’s energy extraction setup. In the linear generator setup the energy is taken out by the vertical movement of waves. In most of the energy conversion systems, the energy is extracted by rotating motion by using the rotary generators. This paper is based on the prototype design of moving coil linear generator. The analysis of the prototype is done using the Maxwell finite element software. Finite-Element-Method (FEM) is used to analytically calculate the induced voltage and cogging forces. In this research, the FEM model of a coreless moving coil P.M linear generator has been outlined with an air cored stator. The main aim of the prototype is to convert marine energy directly without conversion from one form of motion to another, in regions the wave height is around 50 cm. A detail machine design formula is derived for the bases of initial prototype design. Prototype is modelled using Maxwell 2D FEM analysis. Hardware setup results were discussed to confirm the design, and to explore the working of the prototype as a generator. The movement of coils is accomplished by buoyancy mechanism of sea waves. The EMF generated is 6 Vp-p according to finite element simulation software. The prototype is able to generate EMF of about 2.5 Vp-p.

The progress in material and manufacturing technologies enables the emergence of new research areas in electromagnetic actuator applications. Permanent magnet (PM) linear motors are preferred to achieve precise position control and to meet the need for high dynamic forces in the seismic shake tables that are used in analyzing reactions of structure models. The design approaches on the linear motors used in the seismic shake tables may vary depending on the desired force, stroke and acceleration values. Especially, the maximum width, the maximum depth, the maximum linear motor length in longitudinal direction and the maximum travelling distance parameters are the primary design criteria in seismic shake table drive systems. In this paper, a design approach for a linear PM brushless direct current (BLDC) motor with high force/volume, force/weight and force/input power ratios is developed. The design was analyzed using two-dimensional (2D) and three-dimensional (3D) finite element method (FEM) approaches through the ANSYS Maxwell software. The mathematically designed linear BLDC motor was manufactured and subjected to displacement, acceleration and force tests that are used in seismic analyses. The results of the experimental tests validate the convenience of the proposed design approach and the selected parameters.

Micropatterning of cells was achieved by the application of micromagnetic fields using ferromagnetic field modulators. These modulators were made of low carbon steel, and micromachined using the wire-cut method. They were engineered to disrupt the regular pathways of magnetic flux lines, and create localized regions of micromagnetic fields. Uniform micromagnetic fields were achieved via design evaluation using Maxwell®2D magnetostatic simulations. Application of the micromagnetic field modulators on Madin-Darby canine kidney (MDCK) epithelial cells demonstrated good cell adhesion and uniform cell columns of 200 μm-wide, spaced 200 μm apart. This approach would be useful towards cell micropatterning for tissue engineering, artificial organ and implant applications.

Abstract This paper presents formulations, computations and investigations of the solutions of classes C00 and C11 for two-dimensional viscoelastic fluid flows in primitive variables u, v, p, τxx, τxy, τyy with Upper Convected Maxwell (UCM) constitutive model using p-version least squares finite element formulation (LSFEF). The main emphasis of the investigations, undertaken in this research work, is to employ the right classes of interpolations and the best computational strategy to address, to illuminate on and perhaps, to answer and resolve whether the “continued obsession of developing newer and newer computational strategies to obtain solutions of Maxwell constitutive equations for ever increasing Deborah number (De) is as meritorious as currently believed. The stick-slip problem is used as a model problem in all investigations. Our investigations reveal the following: a) The manner in which the governing differential equations (GDEs) are non-dimensionalized influences the performance of the iteration procedure for solving nonlinear algebraic equations and thus, computational efficiency achieved. b) C00 class of solutions are always the wrong class of solutions and are spurious. c) In the flow domains, containing sharp gradients of dependant variables, conservation of mass is difficult to achieve specially at lower p-levels. d) C11 solutions are in conformity with the continuity considerations in GDEs. e) An augmented form of the GDEs and associated C00 and C11 formulations are proposed that always ensure conservation of mass regardless of mesh, p-levels and the nature of solution gradients. This approach yields the most desired classes of C11 solutions. f) We demonstrate that UCM constitutive model cannot describe the flow physics at any Deborah number for dilute polymer solutions of constant viscosity due to the fact that I) in UCM model, solvent stresses are a function of Deborah number. Thus, solvent stresses are wrong at any non-zero Deborah number. II) and solvent shear stresses produce elastic normal stresses. Numerical studies presented in the paper support theses findings. UCM model only generates correct flow physics for De = 0 (Newtonian flow). g) Numerical studies, with graded meshes and high p-levels presented in the paper, are aimed towards establishing and demonstrating detailed behavior of local as well as global nature of the computed solutions. Numerical studies are carefully designed and conducted to establish failure of UCM model in describing flow physics as well as failure of computational process. h) various norms are proposed and tested to judge local and global dominance of elasticity or viscous behavior. i) New definitions are proposed for elongational (extensional) viscosity. The proposed definitions are more in conformity and agreement with the flow physics compared to currently used definition. j) A very significant feature of our research work is that we utilize straight forward p-version LSFEF with C00 and C11 type interpolations without linearizing GDEs and that SUPG, SUPG/DC, SUPG/DC/LS operators are neither needed nor used. Fully developed flow between parallel plates and stick-slip problems are used as model problems. It is concluded that UCM constitutive model always simulates incorrect behavior for dilute polymer solutions of constant viscosity regardless of Deborah number (except De = 0) and thus, development of newer computational schemes to achieve success at higher Deborah number is of no consequence.

The direct drive reversing valve is designed in this paper to replace the main reversing valve of the hydraulic die forging hammer system, and a new drive method based on TPMLM (tubular permanent magnet linear motor) is suggested. To verify the feasibility of the drive method, the fluid force suffered by valve core is calculated by using control volume method. After that, force analysis is carried out on the valve core. Based on FLUENT, the flow field analysis inside the valve is conducted. And then theoretical calculation and simulation on the fluid force analysis are discussed. TPMLM (tubular permanent magnet linear motor) is selected as the driving device and it is analyzed by Maxwell 2D. The simulation results of TPMLM show that the magnetic flux density, back electromotive force and output force satisfy the requirement of the reversing valve.

Abstract A Finite Element Analysis (FEA) parametric study of 2D Magnetohydrodynamic (MHD) pump flow is presented. The analysis assumes steady, viscous, incompressible fluid flow in the presence of a magnetic field applied normal to the plane of motion. The fluid is electrically conducting and the analysis is applicable to the design and performance evaluation of DC electromagnetic MHD pumps. The primitive variable Galerkin finite element approach is used to discretize the complete Navier-Stokes equations governing fluid motion which are coupled to both the Maxwell’s equations governing electromagnetic fields, and the conservation of energy equation governing the temperature field. Analysis variables include: velocity; pressure; temperature; voltage; electric field; magnetic flux; current density and pump efficiency. These variables are evaluated for low to moderate values of the magnetic interactive parameter. The velocity field distortion is compared to other numerical results and insight into solution convergence difficulties is presented.
