... 10% addition of silicon to iron, the Curie temperature decreases from 770 ◦ C to 600 ◦ C [8]. In this study, the temperature applied to the silicon-iron alloy stator with 1.78% silicon is about 350-400 ◦ C. Thus, because this value is below the Curie temperature, the stator does not lose its ferroma ...
