9:10 A.M. KEYNOTE PRESENTATION Permanent Magnetic Material Consumption May Be Teetering on the Brink
In 2007, the Global Permanent Magnet Market may have reached 800,000 metric tons and $8.95 billion and is predicted to reach 925,000 metric tons and $11 billion in 2010. Prices can fluctuate based on raw materials, supply, demand and the global economy. Tonnage is a consistent measure. We will look at those factors that can affect the tonnage of Permanent Magnetic materials sold globally. We will examine the effects of population, per capita consumption in developed and developing portions of the world, and applications. The net effect of increases in population, increases in per capita consumption and more new applications than declining applications results in growth.

10:45 A.M. Magnetic Moment and Susceptibility
Calibration Standards
In the past there were available a number of NBS magnetic moment and susceptibility standards for calibrating magnetometers. However, the supply of all those standards was exhausted in 1989. NIST assembled a new precision absolute magnetometer five years ago, and recently finished using it to certify a new series of magnetic standards, including the popular Ni sphere SRM#772a. Here, the measurement technique will be described, along with information on the metallurgy and use of the new standards.

Computing Three-Dimensional Magnetic Field from Solid Circular Cylindrical and Axially Polarized Permanent Magnets by Employing
Toroidal Functions
A method is developed for computing the three-dimensional magnetic field from an axially magnetized circular cylindrical permanent magnet. This method implements toroidal functions which are well suited for numerical computation. Analytical expressions are developed so that one can more easily perform a parametric study in order to quickly optimize a design. The main purpose of this paper is to develop a method of solution for rapidly computing the magnetic induction field produced by a cylindrical permanent magnet. The method introduced in this presentation should provide a useful analytical tool for accurately predicting the magnetic induction field from circular cylindrical permanent magnets.

High Performance, Radially Oriented Nd-Fe-B
Ring Magnets
This presentation will illustrate the unique characteristics of NEOQUENCH-DR, hot formed radially oriented Nd-Fe-B magnets. The production process utilizes thermo-mechanical alignment during hot extrusion where mechanical deformation at an elevated temperature induces a crystallographic alignment and thus radial magnetic alignment of submicron size Nd2Fe14B grains, which is quite different from conventional sintered magnets where magnetic field alignment is used. This unique alignment process allows us to go beyond the limitation of field alignment; smaller diameter and large length to diameter ratio magnets can be produced with high uniformity.

Winding Losses In High Frequency Inductors with Gapped Core Structures
High frequency inductors often exhibit significant losses due to skin effects. Conventional wisdom has held that litz wire should be employed to moderate skin effects, and that the available winding area should be filled with copper to the greatest extent possible. This conventional wisdom breaks down in the case of gapped core structures. A greater winding fill factor does not always lead to lower winding losses. In many cases the lowest loss design is achieved by selectively winding in certain areas of the bobbin window, leaving other areas devoid of copper. This presentation will examine the source of winding losses in high frequency power inductors and introduce a new computer program.

4:30 P.M. Magnetization of Isotropic Magnet Materials: Considerations for Motor Design
Isotropic magnets assume the orientation that is imparted to them in the magnetizing fixture. This makes fixture design a necessary integral part of the motor design process, and can be exploited as an advantage when designing with isotropic materials. For motors and generators magnetization can be tuned to reduce the cogging torque and torque ripple when design of the magnetizing fixture is carried out concurrently with the motor design. A PMDC motor case study will be part of the discussion, and the study demonstrates how the fixture design can be used to improve the motor performance.

Improving Airplane Power Quality through the Implementation of Multiphase Transformers
The need for electrical power on aircraft has dramatically increased in recent years. The nonlinear nature of loads contributes to an unacceptable level of current distortion. Multiphase transformers can significantly reduce current distortion in power conversion and rectification equipment, allowing distortion limits to be met. In aerospace applications where the AC system frequency is 400 Hz or higher, multiphase transformers offer very attractive, low weight and low cost solutions. Practical multiphase transformer approaches are reviewed with the advantages and disadvantages of each solution. The effects of transformer design parameters on performance results are quantified. Test data from selected demonstration hardware is shared.

9:20 A.M. FEATURED SESSION The Science and Business of Magnetic Digital
Data Storage
The magnetic digital data storage industry advances relentlessly. Last year witnessed recognition for some aspects of the fundamental magnetics that make all of that progress possible: The 2007 Nobel Prize in Physics was shared by Drs. Albert Fert (France) and Peter Grünberg (Germany) for the discovery of giant magnetoresistance in thin ferromagnetic multilayer systems. Giant magnetoresistance, or GMR is not the only exquisite science applied in disk drives. Perpendicular media magnetic multilayer disks, mechanisms, electronics and advanced coding techniques have propelled the applicability and usefulness of HDD’s into new realms. In addition to one-terabyte (1 TB = 1 trillion bytes) capacities, at the other end of the capacity scale magnetics advancements have open the possibility of “large” capacity (30 gigabytes) miniature drives of the same size as compact flash cards. The reduction of cost of flash memory has created synergy and cooperation as much as competition between HDD’s and solid-state drives (SSD’s). This lecture will describe the magnetics of hard disk drives in 2008, and will analyze how these advances are shaping the recording industry.

10:45 A.M. Cryocoolers: The Underlying Requirement of Superconductors
Superconductors offer many benefits and advantages over normal materials, but the successful marketing of superconducting systems depends strongly on the quality of the cryocooler used to maintain the low temperatures. Many types of cryocoolers exist today that will achieve temperatures that may range from about 4 K to 80 K. Their current state of development is such that they are now being used successfully in many applications of superconductors. However, all cryocoolers have potential problems that can hinder their use in some new application areas. Learn these potential problem areas and the current research being conducted to reduce or eliminate these potential problems.

Newly-Developed Nd-Fe-B Nanocomposite Magnetic Powders with High Br
Newly-developed grades of Nd-Fe-B based isotropic magnetic powders, called SPRAX-III, are introduced. These nanocomposite structured compounds have high remanence, Br, more than 1 Tesla, good corrosion resistance and long-term thermal stability compared with conventional rapid-quenched powders because of low Nd content and the existence of the nanocrystalline alpha-iron phase. These advantages can be most utilized in “binder-less magnet” produced by a powder compaction process without using binder resins followed by sintering, and “dual molded magnet rotor” made with resin-bonded magnet and powder magnetic core. The former is suitable for micro-motors and the latter for low cogging torque, high-efficiency motors.

New Stemless Valve Uses Magnetic Coupling
Valve stems are one of the primary areas where valve performance fails. These failures are more serious today than they were 10 years ago because of increased safety and emissions standards that are now being required of industry. We propose the elimination of this problem by the use of a basic new valve based on Venturi Off-Set Technology (VOST). The design uses a magnetic coupling to avoid a mechanical penetration through the valve body, eliminating the need for a valve stem that is necessary with conventional valve designs.

2:40 P.M. Core Loss Computational Case Studies: BLDC and SRM Machines
In electromagnetic simulations of complex machines (such as BLDC, SRM etc.), iron losses are difficult to estimate and separate into hysteresis and anomalous losses on the one hand and eddy current losses in the laminations on the other. This is due to the unavailability of specific loss data for materials and/or the difficulty of gauging instantaneous loss frequencies applicable during simulations. We have studied some modern approaches to core loss computations and applied it to two case studies; a Brushless DC Motor (BLDC) and a switched reluctance motor (SRM) that are presented in this presentation. The focus of this work is to study the status of core loss computations for such machines, apply some current methods and study the effects of geometrical and temperature variations on core loss values in these machines.
