Charged EVs | Lowering iron loss in EV motors: new model maps how maze-like magnetic domains reverse in soft magnets

Researchers at Tokyo University of Science have developed a computational model that can trace how intricate “maze domain” structures in soft magnetic materials reverse their magnetization—and identify the energy barriers that drive that process. The goal is to...

Charged EVs | Fraunhofer IZM’s novel SiC inverter hits 99% efficiency in a 1-liter package for 800 V EV drives

Fraunhofer IZM has developed a 500-kW inverter that fits in a volume of 1 liter—500 kVA per liter—with peak efficiency exceeding 99%. The unit was built for Mitsubishi Heavy Industries and is designed for 800 V DC drives, delivering 500 A RMS per phase with an...

Charged EVs | Fraunhofer IISB develops 750 kW hairpin winding traction motor for hybrid-electric regional aircraft, achieving 8 kW/kg

Fraunhofer IISB has developed a 750 kW permanent-magnet traction motor for hybrid-electric regional aircraft, hitting 8 kW/kg power density through a combination of thin-lamination electrical steel, hairpin windings and direct oil-spray cooling. The machine...
