Keep improving: the excellent performance of silicon steel coils in the power industry

When talking about the performance of silicon steel coils in AC magnetic fields, we need to have a deep understanding of the impact of hysteresis losses and eddy current losses on its performance, as well as the importance of silicon steel coils in the power industry.
Hysteresis loss:
Hysteresis loss is the energy loss caused by the magnetization and demagnetization process of silicon steel coils. In an alternating magnetic field, the magnetic moment of the material will frequently flip as the direction of the magnetic field changes, causing the magnetic domains of the magnetic moment molecules to reorganize, thus causing energy loss. Silicon steel coils reduce hysteresis loss by optimizing the lattice structure and chemical composition, such as adding an appropriate amount of silicon. The addition of silicon makes the grain boundaries clearer, thereby reducing the energy loss when the magnetic moment flips. In addition, proper heat treatment of silicon steel coils can also reduce hysteresis loss and further improve its performance under alternating magnetic fields.
Eddy current loss:
Eddy current loss is the energy loss caused by eddy currents in silicon steel coils under alternating magnetic fields. Eddy currents are circular currents produced inside a conductor due to changes in the magnetic field. During the manufacturing process of silicon steel coils, an extremely thin layer of insulation is usually applied to the surface to reduce the formation of eddy currents. This insulation layer can effectively prevent the generation of eddy current, thereby reducing eddy current losses. In addition, the thickness of the silicon steel coil will also affect the size of the eddy current loss. Thinner silicon steel coils are usually chosen because eddy current losses are proportional to the thickness of the material. Therefore, by controlling eddy current losses, the performance of silicon steel coils under high-frequency alternating magnetic fields can be improved, thereby improving the efficiency and stability of power equipment.
Applications in the power industry:
As a key material in the power industry, silicon steel coils play an important role in power equipment such as transformers, generators and motors. Transformers are devices that transfer electrical energy from one voltage level to another, while generators and motors convert mechanical energy into electrical energy or vice versa. In these devices, silicon steel coils are used as core material to concentrate and transmit magnetic fields. Excellent magnetic properties and low losses allow silicon steel coils to improve the energy efficiency of equipment and reduce energy waste.
By optimizing the hysteresis loss and eddy current loss of silicon steel coils, its performance in AC magnetic fields can be improved, thereby providing reliable support for the development of the power industry.
