Abstract :
The technical aspects of two-dimensional measuring equipments for electrical steel are described. The choice of the appropriate field sensors and the important point of the control of B&oarr;(t) are described. The equipment described is designed to measure the two-dimensional properties of square shaped single sheets of all qualities of electrical steel covering the technical frequencies and induction ranges of the major applications. The equipment is useful for the manufacturers of electrical steel to control the texture of their material and for designers of machines to know about the properties of the material under two-dimensional excitation, which in case of rotational flux conditions are different from the one-dimensional properties measured with the Epstein frame or single sheet testers
