  Excellent magnetic performance Efficient magnetic flux conduction: The structural design of the EI type core is conducive to the efficient conduction of magnetic flux. The combination of its “E” and “I” shapes constructs a relatively ideal magnetic circuit, which can guide the magnetic flux to pass through in a concentrated and stable manner and reduce magnetic flux leakage. Taking the power transformer as an example, this structure can concentrate most of the magnetic flux inside the core, reduce leakage loss, and improve the overall efficiency of the transformer, generally increasing the energy conversion efficiency to more than 95%. Good magnetic permeability characteristics: EI type cores often use materials with high magnetic permeability such as silicon steel. In power frequency transformers, EI cores made of silicon steel sheets can generate higher magnetic flux density at lower excitation currents. For example, the common oriented silicon steel sh...

Effect on eddy current losses The thickness of silicon steel sheets is closely related to eddy current losses. When the thickness of silicon steel sheets increases, the loop area formed by eddy currents increases, and eddy current losses rise sharply. For example, if the thickness of silicon steel sheets is increased from \(0.3mm\) to \(0.6mm\), the eddy current losses will theoretically become 8 times the original value when other conditions remain unchanged. This will not only cause serious heating of the iron core when the motor is running, but also reduce the energy utilization rate of the motor, resulting in a large amount of electric energy waste. On the contrary, using thinner silicon steel sheets, such as the common \(0.2 – 0.3mm\) thickness, can effectively reduce the eddy current loop area, significantly reduce eddy current losses, and improve the operating efficiency of the motor. Effect on magnetic permeability Thinner silicon steel sheets have advantages in...

In the modern electrical industry, silicon steel sheet is an extremely important soft magnetic material, widely used in various types of electromagnetic equipment such as motors, transformers, reactors, etc., and plays a key role in the efficient operation of the power system. Silicon steel sheet, also known as electrical steel sheet, is a silicon-iron alloy with a silicon content of 0.5%-4.5%. The addition of silicon significantly increases the resistivity of steel and reduces the eddy current loss generated by the iron core in the alternating magnetic field, which is an important characteristic of silicon steel sheet that distinguishes it from ordinary steel. At the same time, silicon steel sheet also has a higher magnetic permeability, which can conduct magnetism more effectively, so that electromagnetic equipment can generate sufficient magnetic flux under a smaller excitation current, greatly improving energy utilization efficiency. From the manufacturing process p...
