Summary form only given. The magnetic core of a transformer for welding devices has a moving magnetic shunt. The shunt can assume several different positions to modify the flux leakage values. These transformers are made to supply high current values: saturation of the magnetic core leads to strongly deformed voltage and current.

Gwan Soo Park; Sang Ho Park IEEE Transactions on Magnetics, 2004
In magnetic flux leakage (MFL) type nondestructive testing (NDT), there could be velocityinduced eddy currents during the sensing, which might cause the distortion of the defect signals. In this paper, the distortions of the sensing signals are analyzed by using threedimensional finiteelement analysis with velocityinduced eddy currents, and then, the compensation scheme of the signal distortion is presented to obtain ...

This paper investigates the radial inserted permanent magnet magnetic coupling design based on additive manufacturing (namely 3D printing). 3D printing prevents the use of adhesives or rivets in the manufacturing process of integrating the main structure; thus, the flux leakage is cut down compared with traditional magnetic coupling. Likewise, a honeycomb structure is applied to the shoe parts of the ...

Magnetics and Magnetic Equivalent Circuits
This chapter sets forth the background needed to analyze electromagnetic and electromechanical systems. It includes a review of magnetics, particularly magnetostatics. The notion of magnetic equivalent circuits is explored as a fairly accurate technique for the analysis of magnetic systems. The chapter talks about (a) Ampere's law, and the relationship between magnetomotive force (MMF) sources and MMF drops in the form of Kirchhoff's MMF law, (b) the relationship between fluxes going into a common volume or node that is governed by Kirchhoff's flux law, and (c) Ohm's law for magnetic equivalent circuits. A section describes the relationship between the magnetic equivalent circuit and the corresponding electric equivalent circuit, and highlights the concepts of flux linkage and inductance. It explains leakage permeance so as to create a more accurate magnetic model, and the flux path. The final section of the chapter discusses finite element analysis (FEA), another technique for magnetic analysis.

Distributed Windings and Rotating Electric Machinery
This chapter focuses on a complicated winding arrangement known as a distributed winding, which is often used in rotating electric machinery. In these machines, the goal is to establish a continuously rotating set of north and south poles on the stator, which interact with an equal number of north and south poles on the rotor, to produce uniform torque. The winding function has three important uses. First, it is useful in determining the MMF caused by distributed windings. Second, it is used to determine how much flux links a winding. Third, the winding function is instrumental in calculating winding inductances. The chapter talks about the airgap magnetomotive force (MMF). It explains the calculation of inductances of distributed windings. The problem of the computation of leakage inductance of a stator winding and the problem of finding the resistance of a distributed winding are considered.

HBFEM for Nonlinear Magnetic Field Problems
This chapter discusses mainly the numerical modeling and analysis of electromagnetic fields in switching power supplies. It uses harmonic balance analysis, combined with the finite element method (FEM), to solve problems arising from nonlinear, harmonic, eddycurrent and power loss problems of transformers used in switching power supplies. The chapter also discusses the harmonic balanceFEM (HBFEM) model and computed results, compared with experimental results. The harmonic components of current and magnetic flux can help to accurately analyze and design the magnetic core and winding structures, and further determine the power loss and leakage flux in the magnetic system. The numerical model of voltage excitation with a nonlinear magnetic field is more accurate than conventional magnetic fieldonly analysis. The EM full wave solution can be obtained from HBFEM based numerical computation. To verify the HBFEM based solution, a singlephase direct current (DC)biased switching transformer with a voltage source driven model is used.
