Why should the core silicon steel sheet be coated with insulating paint on each floor?
In order to reduce the heating of the core by eddy current, a layer of insulating paint is applied on each layer of silicon steel sheet, so that the eddy current can be limited to each piece of silicon steel sheet, and the eddy current will be greatly reduced.
This is to prevent the core of silicon steel sheet, each block as far as possible not to produce iron mutual conduction, in order to avoid the iron conduction when the eddy current, resulting in iron core serious heat, burn out equipment and coil.
