The iron core of the DC solenoid: use low carbon steel or pure iron or soft iron. 2. The core of AC electromagnet: made of silicon steel sheet. It can reduce eddy current losses. The iron core of an AC electromagnet always works in an AC state. Power loss is not only caused by the resistance of the coil, but also occurs in the iron core magnetized by alternating current. The power loss in the iron core is usually called "iron loss". Iron loss is caused by two reasons, one is "hysteresis loss" and the other is "eddy current loss". Hysteresis loss is the iron loss caused by the hysteresis phenomenon during the magnetization process of the iron core. The size of this loss is proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of the core of a transformer made of silicon steel is small, which can greatly reduce the heat generation. Since silicon steel has the above advantages, why not use a whole piece of silicon steel as the iron core but process it into sheets? This is because the sheet core can reduce another type of iron loss - "eddy current loss". When working, there is alternating current in the solenoid valve coil, and the magnetic flux it generates is of course alternating. This changing magnetic flux produces an induced current in the iron core. The induced current generated in the iron core circulates in a plane perpendicular to the direction of the magnetic flux, so it is called eddy current. Eddy current losses also heat the core. In order to reduce eddy current losses, the core of the electromagnet is stacked with silicon steel sheets that are insulated from each other. The thickness of the silicon steel sheets is generally 0.35-0.5mm to allow eddy currents to flow in a narrow and long circuit and pass through a smaller cross-section to increase the eddy currents. The resistance on the path;at the same time, the silicon in silicon steel increases the resistivity of the material and also plays a role in reducing eddy currents. 3. Use polyester enameled wire for the electromagnet coil. The above is an introduction to what materials are used for solenoid valve cores and which material is better for solenoid valve cores.
