Vacuumschmelze Supports Satellite Project

Advanced materials produced by VAC are out in space. A group of students at the university Scuola universitaria professionale della Svizzera italiana (SUPSI) asked the Hanau-based company for assistance in the construction of a small cubiform satellite called TIsat-1. The satellite has a mass of one kilogram and an edge length of 10 centimeters. The Swiss students are taking part in an international university program called CubeSat. VAC supplied rods of PERMENORM 5000 H2 in various diameters, used for magnetic oscillation control, and permanent magnets made of VACODYM, which enable the earth's magnetic field to be used as orientation for the satellite. This assistance gained VAC the status of official sponsor of the project.


TIsat-1 saw lift-off on 12 July last year at Sriharikota Space Center in India, when the satellite was launched into space from the PSLV-C15 rocket. It has transmitted signals back to the earth ever since.


VACODYM magnets are produced from neodymium-iron-boron alloys and have the highest energy densities currently available. The magnetic properties of this group of materials are due to their strongly magnetic Nd2Fe14B matrix phase with high saturation magnetization and high magnetic anisotropy. The magnets also have good mechanical properties due to their ductile neodymium-rich binder phase along the grain boundaries.


PERMENORM 5000 H2 is a 48 percent NiFe alloy with relatively high saturation magnetization (1.55 T) and moderate initial and maximum permeability. PERMENORM 5000 H2 is supplied with a large-grain isotropic structure and is suitable for a wide range of applications including summation current transformers and relay components for FI switches, transducers, transformers, power chokes, filters, rotor and stator cores, coil cores for stepper motors in quartz clocks, flux concentrator plates and pole pieces in magnetic valves.

cobhamElectromagnetic Simulator Accelerates the Design Optimization of Custom Transformers
Electromagnetic simulation software is a key tool in the design optimization of power transformers for Kolektor Etra, the Slovenia based electrical equipment manufacturer. The Opera-3D software package is being used for a diverse range of design related tasks, from the detailed characterization of design aspects such as eddy current losses by quantifying stray magnetic flux, to comparing the efficiencies of different construction and geometry ideas for transformers. In a recent analysis of magnetic shield placement in a three-phase power transformer, the company was able to reduce total eddy current losses by as much as 30 percent, leading to a substantial reduction in transformer price and weight, and reduced long-term operating costs for the transformer operator.

Kolektor Etra manufactures a wide range of power and generator transformers with ratings up to 500 MVA and voltages up to 420 kV, as well as distribution transformers rated up to 3150 kVA. The company has been in existence for 78 years, and in addition to its long-term domestic markets, it now sells extensively in mainland Europe and Scandinavia.

Before investing in Opera-3D, Kolektor Etra used some free finite element software to perform tasks such as flux density and other electro-magnetic calculations. However, the lack of any 3D modeling capabilities meant that the company found it difficult to optimize their design in cases of unsymmetrical geometry, such as winding exits, core clamping structures, etc. It therefore took the decision to move to a professional finite element package that offered 3D modeling.

After evaluating electromagnetic design software from several vendors, Kolektor Etra chose Opera-3D from the Vector Fields Software product line of Cobham Technical Services. Aside from its powerful 3D electromagnetic modeling capabilities, the principal reasons for the choice were that the software provides a simple means of calculating eddy current losses and has an intuitive user interface. Kolektor Etra was also impressed by Cobham's technical support.

Like most power transformer manufacturers, Kolektor Etra is under constant pressure to improve product efficiency by optimizing insulation design and reducing electrical losses, which involves a host of design trade-offs such as insulating distances, insulation thickness, choice of electromagnetic shields, and the placement and geometry of internal and external structural elements. These issues are compounded by the desire to create ever more compact designs, in order to save on materials.

According to Andrej Jurman, Head of Kolektor Etra's electrical design department, "We use 3D Opera models to optimize the insulation design of transformer winding exit structures, and also make use of 2D models for designing the insulation between windings. But perhaps the most significant benefit is that we can now calculate and estimate the value of eddy current losses caused by stray magnetic flux. Although it is almost impossible to obtain the exact results (mostly because of the unknown magnetizing curves of ferromagnetic materials and consequently an unknown value of surface impedance), our engineers now have a very powerful means of evaluating and comparing the performance of different design concepts."

Kolektor Etra recently conducted some research into eddy current losses due to stray magnetic fields that occur in the conductive structural parts of a three-phase oil-filled power transformer, particularly in the tank walls. After constructing a three dimensional geometric model, Kolektor Etra used Opera and a time harmonic 3D model at power supply frequency to investigate the effect of different configurations of magnetic screening shield and the shape of core clamping structures on performance. Analysis showed that the stray flux losses which are part of transformer short circuit losses were significantly reduced by approximately 30 percent.

As Andrej Jurman points out, "Gaining a clear picture of the effect of design changes can provide significant cost-savings, which is why we regard the Opera electromagnetic field simulator as such a useful tool. Although the losses caused by stray fields are very hard to separate out from measured short circuit losses in a transformer accurately, modeling enables us to see the shape of stray flux and the places with the highest local loss generation visually. In this way we can evaluate and improve the efficiency of our designs and perform certain measurements. Because a large proportion of our transformer products are one-off designs, we do not model every transformer in detail - but our simulation results heavily influence our general design strategy, helping to maximize the efficiency of every product we make and providing us with a tool for continuous optimization."

Comsol Introduces the Microfluidics Module
Comsol, Inc. has released the Microfluidics Module. Based on COMSOL Multiphysics, the Microfluidics Module brings easy-to-use tools for the study of microfluidic devices and rarefied gas flows. The module is designed for researchers, engineers and experimentalists in the fields of microfluidics and vacuum science. Target application areas include lab-on-chip devices, digital microfluidics, biosensors, electrokinetic and magnetokinetic devices, inkjet technology and vacuum system design. The module is accompanied by a suite of tutorial and industrially relevant models that serve as both instructional examples and as a foundation for future work.


“The simulation of microfluidic devices frequently requires multiple physical effects to be incorporated,” said Dr. James Ransley, developer of the Microfluidics Module with COMSOL, Inc. “The Microfluidics Module offers a range of tools to deal with single- and multi-phase flows, transport and chemical reactions, flow in porous media and rarefied flows. Thanks to the single user-interface in COMSOL for modeling all physics, these phenomena can be seamlessly coupled with thermal and electromagnetic effects.”


The Microfluidics Module includes interfaces for single-phase flow.

With these interfaces users can simulate such applications as compressible gas flows at low pressures, non-Newtonian flows (for example blood flow), and laminar and creeping flows that typically occur in lab-on-a-chip systems.


A particular strength in this module is its modeling interfaces for executing two-phase flow simulations using the level set, phase field, and moving mesh methods. A variety of important fluid-interface effects are included such as surface tension forces, capillary forces and Marangoni effects.


These flow simulation tools and the multiphysics capabilities of Comsol make it easy to set up coupled electrokinetic and magnetohydrodynamic models for the simulation of electrophoresis, magnetophoresis, dielectrophoresis, electroosmosis and electrowetting effects that are used alone or in combinations in both existing and emerging passive electronic display technologies for their basic function.


“We strongly believe that the Microfluidics Module will offer a very attractive set of tools for our electronic display customers,” said Dr. Ransley. Chemical diffusion for multiple dilute species is also included in the module, enabling the simulation of processes occurring in lab-on-chip devices and biosensors.


The Microfluidics Module comes with a new free molecular flow interface that uses the fast angular coefficient method and allows for simulations where the molecular mean free path is much longer than the geometric dimensions. Combined with COMSOL's LiveLink interfaces for industry-standard CAD packages, this tool enables users to run quick parametric studies of chamber geometries and pump configurations.


"The Microfludics Module combines proven and robust multiphysics solvers with the easy-to-use user interface of COMSOL together with a range of solutions targeted at microfluidics applications," said Dr. Ransley. "The net result is a product with unprecedented ease of use which can handle arbitrarily complicated industrial and academic problems."

apaustriamicrosystems Introduces AS5410 Absolute Linear Position Sensor IC as First Product of 3D Hall Platform
austriamicrosystems, a global designer and manufacturer of high performance analog ICs, has introduced the AS5410 linear position sensor, the first product of a fully-featured 3D Hall platform. The 3D Hall sensor solution senses absolute position in automotive and industrial applications and provides highest resolution position information.


The AS5410 allows absolute position sensing of a simple two-pole magnet immediately after starting up the device without the need for a prior reference run within the application. Position sensing is possible over large mechanical travel distances even with very small magnets: a travel distance of 40 mm does not pose a problem for a small, 4 mm by 4 mm by 3 mm sized NeFeB magnet, for example. Moreover, the 3D Hall solution’s output remains stable even when the device is subject to external stray magnetic fields. This feature is the result of a special differential measurement technique including several 3D Hall sensor elements. Programming the internal EEPROM of the AS5410 allows converting a wide range of geometries including curved movements, non-linear scales, and tilted chip/magnet geometries into a linear output signal. In order to achieve a perfectly linearized output (up to 0.5 percent accuracy), the AS5410 linear position sensor provides an internal linearization table with 33 base points. With four preset basic operating modes which are selectable via SPI, the austriamicrosystems AS5410 3D Hall encoder offers quick and easy configuration. All signal conditioning is on chip, including compensation for temperature effects.


“The AS5410’s unique differential architecture makes it perfect for use in position sensing applications that include not only dust, dirt and moisture but also unwanted magnetic fields,” said Bernd Gessner, senior VP and general manager business unit Automotive at austriamicrosystems. “The unique AS54xx family of 3D Hall magnetic encoder ICs is a fundamental addition to our current magnetic sensor product portfolio with a focus on both the automotive and industrial markets.”


A portfolio of 3D Hall encoder products is being developed to operate up to 150°C and from a supply up to 18 V.

The AS5410 3D Hall sensor is sampling now. Production quantities will be available in Q3. Pricing starts at $ 3.75 in 1,000 piece quantities.

USMMA Lauds Legislation to Reduce Economic and Security Risks
The United States Magnetic Materials Association (USMMA), a trade association dedicated to the reestablishment of the entire supply-chain of materials used in magnet systems, welcomes the introduction of the Critical Minerals Policy Act of 2011 (S. 1113) by Senator Lisa Murkowski (R-AK). This timely legislation, which received the bipartisan support of 16 co-sponsors, represents a comprehensive solution to market uncertainties that plague important elements of the national security and green technology industrial bases. USMMA applauds Senator Murkowski for her leadership on this issue and urges the Senate to move quickly on considering this bill.


The Critical Minerals Policy Act acknowledges the untenable position in which the US finds itself: dependent on unreliable foreign sources for those materials that are critical to much-needed military applications and certain energy-saving components. The bill successfully addresses the full range of issues – resource identification, permitting, manufacturing, workforce issues and research and development – that hinder the participation of US industrial actors in the critical minerals and rare earths market. It does so through pragmatic steps such as: requiring a complete commercial market analysis of supply and demand; creating a process to designate critical minerals for special treatment by the US Government; establishing an interagency working group to lower barriers to entry in the critical minerals market; and promoting international cooperation between the United States and our allies in this important area.


USMMA President Ed Richardson said, “Senator Murkowski’s bill is a tremendously useful complement to H.R. 1388, the Rare Earths Supply-Chain Technology and Resources Transformation Act of 2011 as introduced by Representative Mike Coffman of Colorado. Both bills emphasize the importance of taking practical steps in the near-term to address existing vulnerabilities in the rare earth supply-chain and thus mitigate those risks associated with our national security. We endorse the Critical Minerals Policy Act of 2011 and look forward to working with senators and their staffs on this truly importance piece of legislation.”

Great Western Minerals Group CEO Testifies Before US Congress Regarding Pending Critical Minerals and Rare Earth Legislation
Jim Engdahl, president and CEO of Great Western Minerals Group Ltd. (GWMG), provided expert testimony to the US House of Representatives Subcommittee on Energy and Mineral Resources on two key pieces of legislation: the National Strategic and Critical Minerals Policy Act of 2011 (H.R. 2011) and the Resource Assessment of Rare Earths Act of 2011 (H.R. 1314).


He urged Members of Congress to work together on a bipartisan solution to the rare earths and critical materials crisis in the US and incorporate provisions from both bills under consideration to "demonstrate important leadership in the global community regarding the ever more important issues surrounding the United States’ precious natural resources."


"These bills offer important elements of a much-needed comprehensive solution to challenges in developing a complete, reliable and competitive rare earth supply-chain in the US," Engdahl said. Arguing that a solid understanding of the availability of critical minerals is a key starting point for their successful development, he cited specific ideas within the pending legislation as necessary: a supply-chain analysis to inform the market of potential shortages; creation of a small inventory of those rare earths in short supply; and development of downstream capabilities to produce metal.


Engdahl also advocated for industry and government officials to reform the current framework for issuing permits to develop rare earth mines. "GWMG does not support shortcuts that skirt important environmental protections," he said. "Rather, we are encouraging a streamlining of the permitting process by the identification of unnecessary bureaucracy and inefficiency in the process." Currently, that process can take up to a decade from application submission to permit approval.
