The role of transformer cores coatings
The core of the transformer forms the magnetic circuit of the transformer, and at the same time it acts as the skeleton of the actuator. The core of Transformer is usually made of silicon steel sheets with 0.35mm thick and the surface coated insulating varnish.
After each piece is coated into insulating varnish, the core is divided into many
Small section conductors. In this case, the resistance of the vortex pump becomes larger.
The painted iron core, though there is eddy current loss (part of iron
Consumption), the consumption is much smaller. Therefore, silicon steel sheets are thinner and need painted.
