Arnold presents customers with answers to electric transportation’s most pressing design and manufacturing challenges. One of which is electrical motors’ high-power density challenge.

Electric motors for traction drive motors typically demand higher power densities than regular induction motors used in the industrial market. This leads transportation motor designers to use a permanent magnet based topology. Permanent magnet electric motors rely on rare earth metals to generate that power. The availability of these materials relies on uninterrupted supply chains in a select few parts of the world. Arnold’s permanent magnets include RECOMA® 35E—the world’s most power-dense Samarium Cobalt (SmCo) magnet. It is specifically created for the most demanding environments, including high speed (100,000 RPM+), high temperature (above 200°C), and highly corrosive environments, as needed in the aerospace, motorsports, and industrial sectors.

Arnold offers a broad-based, ITAR & DFARS defense-compliant source of supply for Samarium Cobalt and neodymium iron boron (NdFeB or “neo”) magnets used in electric motors. Also, Arnold’s recent partnership with Cyclic Materials of Kingston, Ontario will provide another supply source for these critical resources. Arnold and Cyclic Materials are contributing to the domestic economy by creating the world’s first circular supply chain for rare earth materials through reclamation.
