The iron single crystal has a preferred direction more conducive to magnetization. As shown in Fig. 1, the easy axis (of magnetization) lies along the &lt;100&gt; crystal axis, that is, along the edge of the cube. The hard axis extends from one corner to the diagonally opposite corner, the &lt;111&gt; crystal axis. (Fig. 1)<\/p>\n<p>This means higher permeability and lower core loss in the rolling direction, the &#8220;cube-on-edge&#8221; direction. When the bulk of the grains in a lamination are aligned this way, the lamination can be cut to take advantage of the performance enhancement.<\/p>\n<p>During rolling into strip, the body-centered-cubic (BCC) Si-Fe crystals are stretched and flattened, optimizing the magnetic properties in the rolling (easy) direction, along the length of the strip. In this contrast-enhanced photo (Fig.2) we can see the elongated and flattened structure of Grain Oriented Electrical Steel (GOES).<\/p>\n<p>When a final heat treatment is performed, nearly isotropic magnetic properties are achieved within the plane of the strip due to the almost total elimination of the grain structure.<\/p>\n<p>Arnold&#8217;s treatment processes work to obtain the preferred orientation in the rolled silicon steel strip. The process involves a combination of cold working and heat treating to produce a strip where most of the metal grains are oriented along the rolling direction. While the material is not uniform in all directions, many components such as wound cores and stamped\/stacked E cores can be made to maximize the positive aspects of orientation.<\/p>\n<h2>Electrical steel for power dense motors and transformers<\/h2>\n<p>Many types of electrical devices use a soft magnetic material as the flux-carrier. Silicon-iron (Si-Fe), often referred to as \u201celectrical steel\u201d is the most commonly used material for motors, generators, transformers, and inductors.<\/p>\n<p>High permeability, low coercivity, and ductile properties make Arnold\u2019s Non Grain Oriented (NGOES) silicon steel a perfect match for your high speed, high efficiency motors and transformers applications. Each type of Silicon Steel is available in a variety of thicknesses and widths. Both types have particular advantages over alternative materials for a range of applications. When optimally applied to a particular application, each type offers more efficient use of electrical steel, resulting in higher power density and energy savings.<\/p>\n<h3>Matching the orientation to the application<\/h3>\n<p><strong><a href=\"https:\/\/www.arnoldmagnetics.com\/materials\/non-grain-oriented-electrical-steel-ngoes\/\">Arnold&#8217;s NGOES Silicon Steel<\/a>,<\/strong>\u00a0manufactured under the trade name\u00a0<strong>Arnon\u2122<\/strong>, is best suited to\u00a0<strong>rotating machinery<\/strong>\u00a0that provides a continuously changing angle of incidence of the applied field relative to the lamination steel rolling direction.
