| | PDF (627 KB) | HTML

We describe a new technique, micro-Brillouin light scattering spectroscopy, for investigation of spin wave dynamics in magnetic nanostructures. The technique offers advantages for studies of small magnetic squares with closure domain structure and magnetic nanoelements similar to those used in magnetic random access memory. The technique is particularly effective in two-dimensional mapping of spin... View full abstract»

• ### Influence of ${hbox{Fe}}_{2}{hbox{O}}_{3}$ Stoichiometry on Initial Permeability and Temperature Dependence of Core Loss in MnZn Ferrites

| | PDF (378 KB) | HTML

We investigated the relationship between magnetic properties of MnZn ferrites and Fe2O3 stoichiometry by measuring magnetic properties, electrical resistivity, and density. We used a scanning electron microscope to observe the fractured surface of sintered samples. MnZn ferrites were prepared by adapting the conventional ceramic technique. Toroidal cores were sintered at 1355... View full abstract»

• ### Optimal Design of Magnetostrictive Composites: An Analytical Approach

Publication Year: 2008, Page(s):17 - 23

| | PDF (280 KB) | HTML

Giant magnetostriction materials, such as Terfenol-D, have allowed the development of a new class of actuators and sensors based on magnetoelastic properties. However, their mechanical properties are a limiting factor for some applications. Composites, made of Terfenol-D particles in a matrix, can bypass these limitations, improving the overall mechanical properties while maintaining the magnetost... View full abstract»

| | PDF (381 KB) | HTML

We describe a theoretical approach for determining the permeability tensor of polycrystalline ferrites regardless of their magnetization state. To take into account both the demagnetizing dynamic fields related to the magnetic domain and grain shapes and the magnetic interactions between adjoining domains and between adjoining grains, we transform the classical Landau-Lifschitz-Gilbert equation in...

• ### Magnetic Flux Density and Vector Potential of Uniform Polyhedral Sources

Publication Year: 2008, Page(s):32 - 36
Cited by:  Papers (16)
| | PDF (133 KB) | HTML

The magnetic flux density and the magnetic vector potential produced by a uniform current density or a uniform magnetization inside an arbitrary polyhedron are calculated analytically. The obtained closed-form expressions are remarkably simple and provided in an intrinsic vector form, independently of any reference frame. They are well suited to cope with the data structures, i.e., faces-edges and... View full abstract»

• ### A New Identification and Implementation Procedure for the Isotropic Vector Preisach Model

Publication Year: 2008, Page(s):37 - 42

| | PDF (223 KB) | HTML

A factorable Preisach distribution function is a reasonable assumption in modeling soft magnetic materials. With this assumption it is possible to define and employ a single-input Preisach function for easier implementation and identification of a scalar Preisach model. On the basis of this simplification, we developed a new method for identification and implementation of the isotropic vector Prei... View full abstract»

| | PDF (1788 KB) | HTML

A fast measurement system that can characterize a magnet during manufacturing would be a great aid to quality control. The traditional approach measures the magnetic flux density across a specified plane to precisely characterize the magnet. However, this is a time-consuming process. To speed up the magnet characterization, we have developed a new characterization concept based on isomagnetic line... View full abstract»

• ### Analytical Solution for Cogging Torque in Surface Permanent-Magnet Motors Using Conformal Mapping

Publication Year: 2008, Page(s):52 - 65

| | PDF (807 KB) | HTML

We present an analytical method for the calculation of cogging torque in surface permanent-magnet (PM) motors. The cogging torque is calculated by integrating the Maxwell stress tensor inside the air gap. The principle of complex relative air-gap permeance derived from conformal transformation of the slot geometry is used to take into account the effect of slotting and to calculate the radial and ...

• ### Finite-Element Transient Analysis of Induction Motors Under Mixed Eccentricity Fault

Publication Year: 2008, Page(s):66 - 74
Cited by:  Papers (71)
| | PDF (572 KB) | HTML

In a three-phase squirrel-cage induction motor, eccentricity is a common fault that can make it necessary to remove the motor from the production line. However, because the motor may be inaccessible, diagnosing the fault is not easy. We have developed a time-stepping finite-element method (FEM) that identifies mixed eccentricity (a combination of static and dynamic) by analysis, without direct acc... View full abstract»

This paper presents the design, prototyping, and analysis of a relatively small and cheap axial-flux three-phase coreless permanent-magnet generator. The excitation of the machine is done by rectangular flat shaped neodymium-iron-boron magnets. A two-dimensional model of the machine is analyzed with finite-element software to obtain the machine parameters. One special feature of the constructed ge... View full abstract»

• ### Augmentation of Short-Span Seeking Performance Using Dynamic Saturation

Publication Year: 2008, Page(s):81 - 83

| | PDF (207 KB) | HTML

We present a method for improving the short-span seeking performance of a recently proposed compensator-based control system for a dual-stage servo actuator. The method consists of replacing a constant saturation nonlinearity in the secondary loop of the dual-stage control system by a dynamic saturation nonlinearity. This results in a significantly faster response of the secondary actuator and hen... View full abstract»
