Iron core transformer 6V400mA
Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of silicon (silicon also known as silicon) steel, its silicon content is 0.8~4.8%. The core of the transformer made of silicon steel is because silicon steel itself is a magnetic substance with strong magnetic conductivity, and in the energized coil, it can produce a large magnetic induction strength, which can reduce the size of the transformer. We know that the actual transformer always works in the AC state, and the power loss is not only in the resistance of the coil, but also in the core under the magnetization of the alternating current. Usually the power loss in the iron core is 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 presence of hysteresis phenomenon during the magnetization of the iron core, and the size of this loss is proportional to the size of the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is small, and the core hysteresis loss of the transformer is small, which can greatly reduce its heating degree. Since silicon steel has the above advantages, why not use a whole piece of silicon steel as an iron core, and also process it into sheets? This is because the chip core can reduce another type of iron loss - "eddy current loss". When the transformer is operating, there is an alternating current in the coil, and the magnetic flux it generates is, of course, alternating. This varying magnetic flux induces an electric current in the core. The induced current generated in the iron core circulates in a plane perpendicular to the direction of magnetic flux, so it is called eddy current. Eddy current losses also heat up the core. In order to reduce the eddy current loss, the iron core of the transformer is stacked with silicon steel sheets insulated from each other, so that the eddy current passes through a small section in a narrow and elongated circuit to increase the resistance on the eddy flow 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.
