Global demand for electric vehicles is booming, with 2023 sales expected to grow 35% after a record-breaking 2022. This explosive growth has led to electric vehicles moving from a 4% share of the overall care market to a 14% share in 2022. Three markets are dominating the EV industry – China, Europe, and the US. China is the frontrunner, manufacturing more than half of all electric vehicles. However, the U.S. is ramping up EV production and by investing more than $90 billion in EV manufacturing. Permanent magnet motors are by far the most commonly used electric motor in the EV market thanks to their high-power density, torque density, and efficiency.

This panel discussion will focus on both government and industry efforts to develop a robust North American supply chain of permanent magnets to support the energy sector industrial base (ESIB). Rare earth magnets, such as sintered neodymium-iron-boron (NdFeB) magnets, are especially important to the ESIB as they are critical components of traction motors in electric vehicles and direct drive generators in offshore wind turbines. Yet, nearly all supply chain stages of sintered NeFeB magnets are concentrated in China, posing a potential vulnerability for ESIB supply chains required to meet climate goals.

As a proud sponsor of both the Belgian Formula Student and the Belgian Innoptus Solar electric race teams, Magcam has effectively employed its magnetic field camera technology and application expertise to enhance the performance of the permanent magnet rotors used in the electric motors in their respective electric race cars.

The Formula Electric car is powered by four radial-flux motors, whereas the Innoptus Solar car operates with an axial-flux motor. In both scenarios, we started the optimization process by measuring a large quantity of individual magnets using our magnetic field camera scanner. From the resulting magnetic field maps, detailed quality parameters were extracted, including overall magnet strength, magnetization angle error and localized magnetic homogeneity. By ranking these magnets based on the derived quality parameters, we were able to select the highest quality magnets for rotor assembly. This first crucial step assures that only qualified magnets are used. The assembled rotors were subsequently measured by Magcam's advanced radial/axial-flux rotor scanner.

Since the fusion ignition breakthrough at the Lawrence Livermore Laboratory in late 2022,
billions of dollars have been funneled into achieving commercial fusion energy at scale and international
sprint has ensued to be the first company to achieve it. As a clean, limitless energy source, fusion could
solve the world’s energy problems and make today's climate change debate moot. Yet, to achieve
commercial fusion energy at scale, the world needs more of a critical component that is in short supply -
high temperature superconducting (HTS) magnetic wire. HTS magnetic tape is the only material that can
generate a strong enough magnetic field to achieve fusion energy in a device that is substantially smaller
than alternative technologies. This keynote talk will cover how the latest advancements in HTS magnets
are impacting the race for fusion energy and how one community aims to create an ecosystem to
support technological advancements in HTS magnets.
