The hysteresis losses of silicon steel can be significantly affected by the presence of stress. These losses occur when the magnetic domains in the steel align and realign with changes in the magnetic field, resulting in the conversion of electrical energy into heat. This reduces the efficiency of electrical devices that use silicon steel as a core material.
When stress is applied to silicon steel, it causes changes in its crystal structure and introduces defects. These defects can disrupt the movement of magnetic domains and increase the resistance to domain alignment, leading to higher hysteresis losses. The defects created by stress act as barriers for the movement of magnetic domains, requiring more energy for realignment with changes in the magnetic field. Consequently, more energy is converted into heat, increasing hysteresis losses.
Moreover, stress can also impact the magnetic properties of silicon steel, such as saturation magnetization and permeability. These properties directly affect the efficiency of electrical devices. Stress-induced changes in these properties can further worsen hysteresis losses.
To mitigate the impact of stress on hysteresis losses in silicon steel, manufacturers often use stress-relieving techniques during the manufacturing process. These techniques aim to reduce residual stress within the material and enhance its magnetic properties. By minimizing stress-induced defects and optimizing the crystal structure, the movement of magnetic domains can be facilitated, thus reducing hysteresis losses.
In conclusion, stress in silicon steel can increase hysteresis losses by introducing defects and disrupting the movement of magnetic domains. Manufacturers employ stress-relieving techniques to minimize these losses and improve the efficiency of electrical devices that utilize silicon steel.

When stress is applied to silicon steel, it alters the crystal structure and introduces defects within the material. This can disrupt the movement of magnetic domains and increase the resistance to domain alignment, leading to higher hysteresis losses. The stress-induced defects act as barriers for the movement of magnetic domains, causing them to require more energy to realign with changes in the magnetic field. As a result, more energy is converted into heat, thereby increasing hysteresis losses.
Furthermore, stress can also affect the magnetic properties of silicon steel, such as its saturation magnetization and permeability. These properties directly impact the efficiency of electrical devices. Stress-induced changes in these properties can further exacerbate hysteresis losses.
