Effect of sub-micron deformations at opposing strain rates on the micromagnetic behaviour of non-oriented electrical steel.

ABSTRACT: We are entering an era of re-electrification, seeking high-power density electrical machines with minimal resource use. Significant performance gains in electrical machines have been achieved through precise manufacturing processes, including the shaping/cutting of soft magnetic materials. However, most studies have evaluated magnetic performance at a macro level, focusing on components, while the fundamental mechanisms, e.g., how the micromagnetic behaviour is affected by mechanical interference, remain unclear. In this study, we examine the impact of sub-micron deformations at opposing strain rates (10^-2 to 10¹ s^-1) on the micromagnetic behaviour of soft magnetic non-oriented electrical steel.
