|Grain oriented electrical steel has a symmetrical structure in which cubic crystals are all arranged in the direction in which the steel plate has been rolled. This is called the GOSS orientation. It is achieved by a series of rolling and annealing treatments. |
Steel of this type has much better power and permeability properties in the direction of rolling than it has at 90 ° to this direction.
The low power loss is achieved by adding up to 3% silicon to the molten steel. This has the disadvantage, however, that it reduces the magnetic saturation of the steel. The magnetic saturation is measured in Tesla (T).
