Further Processing
Grain oriented electrical steel is used for the manufacture of magnetic cores within transformers. The best magnetic properties are only found in the rolling direction due to the nature of the manufacturing process. If the material is magnetised outside the rolling direction the core losses increase significantly. The extent of this increase varies from a factor of three times at 90 degrees and four times at 60 degrees.
It is therefore essential that the material is magnetised as precisely as possible along the rolling direction throughout the magnetic circuit.
R&D has played a major role in Cogent Power for over 50 years. Although the basic types of electrical steels are based on established technologies, products and processes continue to be improved to meet increasing demands from users for enhanced properties and more cost effective solutions.
Today a major part of the R&D of Cogent Power is carried out in cooperation with experts in different fields outside the company. Important R&D partners are Corus Research Development and Technology and well renowned universities and research institutes. The company is also sponsoring the "Cogent Lectureship of Magnetics" at the Wolfson Centre of Magnetics at Cardiff University.
