Soft magnetic core engineering plays a key role in high-efficiency electric motors, but for higher-frequency applications, soft magnetic composites are also promising. Each stage of motor construction affects the material’s microstructure, and understanding the details of the microstructure is paramount to reaching higher efficiency for electrical motors. Researchers have now created an advanced characterization method to closely examine microscale structural characteristics and changes during manufacturing processes using electron backscatter diffraction.
