Six Sigma in Magnetic Manufacturing
The concept of Six Sigma has become industry standard for defining quality of products and services. Magnetic devices being the heart of the power electronic system performance, customers not only expect, but demand, Six Sigma quality.

Magnetic manufacturing processes greatly contribute to the quality of magnetic devices. Understanding the Six Sigma concepts and the implementation methodology would help 'build-in' the desired Six Sigma quality into the magnetic devices. The 'what', 'why' and 'how to' Six Sigma in magnetic manufacturing will be presented.

Benefit from the presenter's hands-on experience to grasp the seemingly complex methodology of Six Sigma in easy to understand expressions. Actual case histories will be presented highlighting the methodology used and results achieved.

A New Generation of Contactless Magnetic Position Sensors
Discover a new generation of position sensors using recently developed hall probes, which measure the angle of the magnetic field, but not the amplitude as it did in previous decades. The magnetic flux can be generated by a diametrically magnetized ring magnet, with a focus on through shaft 360° angular sensors or by a specific sinusoidal magnetization for linear and short stroke angular sensors. In the last two cases, dedicated magnetization heads are necessary to get a linear variation of the magnetic field direction along the magnet stroke. Learn how your company can benefit from using these new position sensors.

Magnetic Refrigeration Regenerator Materials
The successful introduction of magnetic refrigeration into the market place equally depends on the design of the magnetic refrigerator and on the magnetocaloric properties of the magnetic refrigerant. This presentation will be focused on the latter. Viable magnetic refrigerant materials are those which order ferromagnetically and have a large magnetic entropy associated with the ordering process, which may be second or first order. Most ferromagnets exhibit a second order transition, which takes place over a wide temperature range (e.g. Gd). A few ferromagnets undergo a first order transition which leads to a large entropy change over a narrow temperature range. In the past few years a great deal of effort has been devoted to near room temperature, first order ferromagnets: Gd5(Si1-xGex)4, RMnO3, La(Fe1-xSix)13, MnAs, FeMnPAs and Ni2MnGa. The properties of these six potential magnetic refrigerants will be discussed and compared to those of the Gd prototype.

Ultra High Precision Fluxmeters: Overview and Recent Developments
Fluxmeters are amongst the oldest magnetometers. The magnetics industry knows them mostly as a way of measuring flux density inside a piece of magnetic material. Most industrial users are not aware that very high-precision coils and integrators are also used for high-precision magnetic field mapping. These techniques have been the specialty of accelerator labs such as Fermilab and the CERN; for example, the thousands of magnets for the CERN's Large Hadron Collider (LHC) were all mapped using this technique, with a precision of better than 10 parts per million. Now, a new generation of integrators, with dramatically improved speed and dynamic range, has been developed to study low-level dynamic effects. Learn how these techniques, such as to study eddy current effects, are accessible to industrial users.

Development of Improved Powder for Bonded Permanent Magnets
To meet performance and cost goals for advanced electric drive motors, it is essential to improve the alloy design and processing of permanent magnet powders. Two primary objectives for permanent magnet material are to increase the useful operating temperature for magnets from 120-150°C to 200°C and to enhance the oxidation/corrosion resistance of the resulting powders. These developments should enable a transition from sintered magnets to bonded magnets that use a high temperature polymeric matrix. The planned improvements in materials and processing can permit effective high volume, net shape manufacturing of bonded magnets by gas atomization and injection or compression molding. Nanocrystalline hard magnets with multi-rare earth elements are of interest for their high temperature performance over 200°C. Newly developed MRE2(Fe,Co)14B nanocrystalline hard magnetic alloy with ZrC addition have an unexpectedly high coercivity relative to their grain size compared to the Nd-based alloys.

Energy Savings with Thin Gauge for Motors, Generators, Transformers and Inductors
Approximately 57 percent of generated electric energy in the US is consumed by industrial electric motors. Several percent more is consumed in the transmission lines and transformers distributing this energy. The US now has the largest installed base of wind power generation in the world. Motors, generators, transformers and inductors are being designed to be more energy efficient by utilizing thin gauge Iron-Silicon. Heat build-up in electrical devices is symptomatic of eddy current and hysteretic losses and requires strategies for minimization of losses and for removal of heat. Some old and many new applications take advantage of thin gauge laminations, both unoriented and oriented, to achieve these benefits. Learn how thin gauge proves beneficial for each application and what is the optimum lamination thickness.

Building Nanocomposite Magnets with Novel Approaches
Theoretic calculations have predicted very high energy products for exchange-coupled hard/soft nanocomposite magnets. However, there are still several technical barriers en route to achieve the high energy products. One of the key issues is to control grain size of the hard and soft phases. A bottom-up approach has been adopted recently to produce bulk nanocomposite magnets which involves synthesis of ferromagnetic nanoparticles and compaction of the nanoparticles. By applying newly developed salt-matrix annealing and surfactant-assisted milling techniques, monodisperse ferromagnetic FePt, FeCo and SmCo nanoparticles have been successfully synthesized. These first-ever-available nanoparticles display various hard and soft magnetic properties at room temperature, which are found to be strongly size dependent. Remarkably enhanced energy products have been achieved in the bulk nanocomposite magnets prepared via the novel approaches.

Application Trends in Bonded NdFeB
The trend toward higher efficiency motors in general and toward smaller, lighter weight motors in the automotive industry is creating increased demand for bonded NdFeB (Neo). Bonded Neo magnets can replace ceramic ferrite material and result in a motor of similar performance that is much smaller and much lighter. In many cases the total raw material cost for the Bonded Neo motor is less than that for the ferrite motor. Case studies will be presented with data gathered from the testing of actual motors in the laboratory and from FEA modeling. The performance of bonded Neo at 150°C and above will also be discussed.

Rayleigh-Benard Instability in a Chemically Reacting Ferromagnetic Liquid
The onset of convective instabilities in ferromagnetic chemically reactive fluids affected by buoyancy and a pondermotive force due to magnetization is investigated. Mechanisms of augmenting/suppressing convection are studied. The effect of chemical reactions is to enhance the onset of free convection whereas the ferrofluid dampens it. Chemically reacting flows feature prominently in the majority of energy conversion and propulsion systems. Additionally, reacting flows have become increasingly important in manufacture processes and material synthesis, where they are applied to transform material properties and fabricate new macro, micro and nano structures for a wide range of applications including semiconductors and optoelectronics.

How are We Going to Meet our Growing Needs for Rare Earth Supply?
China is the pre-eminent supplier of rare earth oxides, producing upwards of 97 percent of today’s supply. China’s domestic demand for rare earths is estimated to exceed its production in 2011. The Chinese Government has been introducing significant quotas on the export of rare earths since 2004, effectively limiting exports in 2008 to 34,176 tons, whereas in 2004, a 30 percent reduction from its 2004 output of 48,500 tons. This tightening of supply is of major significance to non-Chinese consumers. World markets critically depend on rare-earth metal oxide raw material supply from mines in existence now or within the next three years. Hear an update on several feasible sources outside of China.

X-Ray Vision of the Inner-Workings of Functional Magnetic Materials -- NEW!
The ability of x-rays to penetrate matter, to probe the atomic length-scale, and to couple to the magnetism of selected atomic species, provides a critical link between a material’s macroscopic magnetic response and the otherwise invisible world of electronic interactions at the atomic scale. Hear examples of recent research where x-ray vision provided unique insight into (a) the atomic origin of magnetic hardness in Neodymium-Iron-Boron (Nd2Fe14B) permanent magnet, (b) the giant magnetocaloric effect in Gadolinium-Silicon-Germanium (Gd5Si2Ge2) alloy, and (c) the pressure-induced increase in magnetic ordering temperature in ferromagnetic-semiconductor Europium-oxide (EuO). The ability to peek into the inner-workings of magnetic materials at the atomic level renders x-ray vision a valuable tool in the quest for search and discovery of novel magnetic materials for diverse applications across the marketplace.

Permanent Magnet Economics
The global economics has significantly affected the pricing and the future of permanent magnet materials and their usage. Prices have risen but will this continue or will there be price declines in the future? There have been design changes in applications as the price of one material changed relative to another, but is this the correct response to price fluctuations?

Robert Wolf, Vice President • Alliance LLC

Modeling of Hysteresis in Soft Magnetic Materials
Discover a new method of modeling the hysteretic behavior in soft magnetic materials. In the new method, the magnetic behavior is considered as a trajectory B(H). The trajectory is based on a measured major symmetric loop that is supplied by the user. This data may be obtained from in-house measurements or published data-sheets, and are imported into OPERA as standard input tables. From this data, the method uses the turning points of the B(H) trajectory to predict the behavior of arbitrary minor hysteresis loops. The method is practical because it makes realistic demands on the user for material data, while providing a good approximation to the true physical behavior.

Enhancing Performance of NdFeB Magnets Through Grain Boundary Diffusion (GBD) and their Effective Application
High temperature magnet applications continue to grow with the advent of electric automotive powertrains and generators. These demanding applications require magnets that provide robust power density while resisting high temperatures. Typically, costly rare-earths are added to overcome demagnetization associated with elevated temperatures at the cost of lowered flux density and consumption of precious rare-earths. New manufacturing processes incorporating Grain Boundary Diffusion (GBD) are currently in development, which minimize rare-earth content while allowing the achievement of high flux densities at temperatures that have not previously been possible. Discover how the GBD process works, anticipated manufacturing processes, achievable magnetic characteristics, and effective design using magnets, which are produced using the GBD process.
