For the past decades amorphous and nanocomposite soft magnets have been a hot topic in the field of strategic materials based on their outstanding soft magnetic properties for a wide frequency-range. These materials successfully entered the market for low-frequency power transformers, high-frequency power electronics, magnetic shields, and sensor applications.Because electric motors account for nearly half of global electricity consumption, advanced soft magnets capable of operating with low losses at high speeds have the potential to greatly provide energy-savings. But the adoption of these unconventional materials for electric motors requires advances in suitable and cost-efficient manufacturing processes.In this work, we examine the role of soft magnetic materials in electric machines and discuss current materials' limitations. Furthermore, we address iron loss modelling strategies. We review recent efforts and technological achievements of emerging amorphous and nanocomposite soft magnets in the high-efficient electric motors field.
