Electrical steel made without special processing to control crystal orientation, non-oriented steel, usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic. Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO.
Among the two types of silicon steel, grain-oriented (GO) and grain non-oriented (GNO), GO is most desirable for magnetic cores. It is anisotropic, offering better magnetic properties than GNO in one direction. As the magnetic field in inductor and transformer cores is always along the same direction, it is an advantage to use grain oriented ...
The advantage of high saturation in a magnetic core is that it can function at higher magnetic field strengths, so the core can be smaller and lighter for a given magnetic flux and power level. Permendur is used for magnetic cores and pole pieces in lightweight transformers and electric motors used in aircraft.
A family of hysteresis loops for grain-oriented electrical steel, a soft magnetic material. B R denotes retentivity and H C is the coercivity. The wider the outside loop is, the higher the coercivity. Movement on the loops is counterclockwise.
He made significant contributions to the field of metals research, and in 1935 he published a paper [1] and patented a method [2] to obtain so-called grain-oriented electrical steel, which has highly anisotropic magnetic properties. This special "grain-oriented" structure was named after its inventor and it is referred to as the "GOSS structure ...
Moving domain walls in a grain of silicon steel caused by an increasing external magnetic field in the "downward" direction, observed in a Kerr microscope. White areas are domains with magnetization directed up, dark areas are domains with magnetization directed down.
