Keynote: Vulnerabilities and opportunities in the sintered NdFeB supply chain for meeting U.S. decarbonization goals

In February 2021, President Biden signed Executive Order 14017 on America’s Supply Chains (EO14017), directing federal agencies to identify and evaluate potential challenges and opportunities facing key supply chains and propose potential policy solutions to address them. As part of this effort, the Department of Energy (DOE), in partnership with the national laboratories, conducted evaluations of the supply chains that encompass the Energy Sector Industrial Base, with a particular focus on technologies required to decarbonize the U.S. economy by 2050. One of these reports focuses on the rare earth permanent magnet supply chain, specifically that for sintered neodymium-iron-boron (NdFeB) magnets, for their prevalent use in traction motors in electric vehicle propulsion systems and direct drive synchronous generators in offshore wind turbines.

Discovery of rare-earth lean high-performance permanent magnets

The development and deployment of high-performance permanent magnets depend on the utilization of suitable magnetic and bonding elements in the anisotropic crystal structure. The first prerequisite is to pinpoint which atoms in the crystal provide magnetization, ferromagnetic transition temperature, and magnetic anisotropy. If these intrinsic permanent magnet properties along with the evolution of microstructure are translated to coercivity and remanence, one can then be equipped with the high-performance permanent magnet. We present here our newly discovered crystallographic site substituted high-performance hexaferrites to rare-earth cobalt to neo magnets applicable in vehicle, wind turbine, magnetic cooling, and other household technologies.

Sintered NdFeB patents - tackling risks in the patent soup

It’s been close to fifty years since the announcement of the new, revolutionary Nd-Fe-B magnet material in 1983. With an estimated global market capitalization of around 20 bn$/year, these magnets present a niche market. Especially sintered NdFeB magnets are gaining attention though, due to their growing importance in green transition.

Panel Session: Raw Materials for Magnets: Will there be enough in time?

The conversion to electric vehicles and the widespread deployment of wind turbines, along with a myriad of other applications of permanent magnets is making the supply chain nervous about our preparation for the future. Will the optimistic forecasts hold true? Will suppliers and producers be able to keep up with the projected increasing demand? Will we have enough when we need it?

Challenges for replacing Nd In NdFeB Magnets with more abundant rare earths

The demand for Neo magnets in traction motors and Windmills spurred a great interest in domestic production. National security issues are a factor as well. China has been a dominant player for the past two decades that resulted in the rest of the world to shut down their magnet plants.

Rare-earth recycling: challenges and opportunities

Rare-earth element (REE) magnets are essential in defense and clean energy applications. The demand for these magnets is expected to follow the growth of the clean energy sector (EV, wind turbines). Since more than 90% of the world's REE magnet production capacity is dominated by China, which is constrained by governmental export quotas, future supply availability is uncertain. At the same time, the magnet end- of-life, industrial scrap and swarf market in US, Europe and Japan is increasing.

Samarium Iron Nitride – the next big thing in magnets

Neodymium (Nd) has been the primary source for most commercial rare earth magnets. However, for years the price of Nd has fluctuated greatly and presents a great supply chain risk. However, as a rare earth material, Samarium is much more stable and can dramatically reduce procurement risks.

Magnetic Circuit Design: Maximum Performance vs Efficiency

Magnetic circuit designers often strive to get the maximum performance while also keep an eye on the circuit efficiency. With limited resources of rare earth materials and supply chain issues, magnetic circuit designers should evaluate the relationship between maximum performance and efficient use of rare materials to help alleviate the rare earth supply issues.

Panel Session: Rare Earth Materials & Magnet Recycling - relieving the supply chain shortages

Rare earth materials are essential in numerous industries including, Critical Infrastructure & Energy, Defense, EV & Automotive, Healthcare and many more. We are seeing exponential growth for the demand of rare earth and critical elements. Similar to where the steel industry was 15 years ago, the need to recycle these elements and materials is important and vital to the future of the market.

Recycling will become an increasingly integral part of the supply chain and will be driven by partners that have focused on collaboration.

Join industry experts as they discuss this demanding industry including the future and importance of the recycling industry and the challenges and barriers facing the market. Hear how the government is playing a role and the new technologies that are changing the Rare Earth Materials Recycling.

Instantaneous Magnetic Field Mapping Enables In-Line Quality Control of Large Magnetic Assemblies

The demand for high-quality customer-specific permanent magnets and magnet assemblies is increasing. Batch quality control or functional tests are no longer an option to meet customers' requirements. Enabling Instantaneous Magnetic Field Mapping of large magnetic assemblies makes a 100% dynamic quality control possible. In this presentation, we will review the process from data acquisition by a 3-axis Hall Magnetic Field Camera to the analysis and QC sorting criteria.

Reduction of Cycle Time and Increasing Magnetizing Field Strength in Magnetization Process and Production

In a line production of car traction motors the magnetization of the assembled rotor is always a time critical process. Big dimensions combined with deep V-shaped configuration of the magnets inside the rotor require a very high energy of the magnetizing pulse. In consequence there is a high temperature rise after each pulse which only can be eliminated by a long re-cooling time of the magnetizing coil.
