Researchers at the University of Pittsburgh (Pitt) Swanson School of Engineering are working with Powdermet Inc., a nanomaterials and advanced materials research and development company in Ohio, to develop a rare-earth-mineral-free electric motor. Most electric motors for electric vehicles rely on permanent magnets made with rare-earth metals, which are a.

As electrification advancement accelerates and more renewables are integrated into the electric grid, improved power electronics systems are needed to convert AC or DC power into a usable form. New semiconductor device materials and advanced magnetic materials can enable an unprecedented combination of voltage levels and power handling capabilities.
However, the latest class of new switching devices, which use so-called ultra-wide bandgap (UWBG) semiconductor materials, will also require improved soft magnetic materials and manufacturing approaches not currently available.
