Abstract Scope |
In this talk, we will present the use of system levels modeling (SLM) for addressing rare-earth elements (REEs) supply challenges for permanent magnets (PMs) applications. PMs enable applications like energy-supplies, national-security, transportation, automation and personal devices. However, the geographical distribution of REEs poses a challenge for sustainable development and use of PMs. SLM tools like finite element analysis can help address such challenge by providing a virtual testbed for determining the actual performance required of PM in a system. SLM can help to determine when coercivity is more important than remanence or when mechanical-robustness is more crucial than weight/size by couple different physics for an application. Via such approach, we have predicted and experimentally validated that low field is required for aligning anisotropic bonded Nd-Fe-B magnets. We have shown the economic impact of replacing Nd-Fe-B with Sm-Co in wind energy applications. This talk will cover other such applications of SLM. |
