Two important conditions for demagnetization: overlapping of magnetic poles and decreasing magnetic field strength. If the ferromagnetic material is demagnetized, the consistency of the magnetic domain arrangement must be disrupted, so that the magnetic domain arrangement is disorderly and does not show magnetism to th···
Transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel that contains silicon (silicon is also called silicon). Silicon steel is used as the core of the transformer, because silicon steel itself is a magnetic substance with strong magnetic permeability. It can produce a large magn···
(1) The iron core touches the shell and clamps. After installation, due to negligence, the stabilizing (positioning) nails on the top cover of the fuel tank were not turned over or removed, causing the iron core to collide with the tank shell; the iron core clamp limbs touched the iron core column; silicon steel sheet ···
If there is no fixing glue, the reasons are as follows:(1) The peripheral burrs of the silicon steel sheet are large, and the overlap gap does not meet the requirements.(2) There is an error in the disc, which causes empty discs, overlaps, and makes the iron core not compact after being stacked.(3) The iron chip has wa···
