Amorphous steel is limited to foils of about 50 μm thickness. The mechanical properties of amorphous steel make stamping laminations for electric motors difficult. Since amorphous ribbon can be cast to any specific width under roughly 13 inches and can be sheared with relative ease, it is a suitable material for wound electrical transformer cores.
The stacking factor (also lamination factor or space factor [1]) is a measure used in electrical transformer design and some other electrical machines. It is the ratio of the effective cross-sectional area of the transformer core to the physical cross-sectional area of the transformer core. The two are different because of the way cores are ...
The solid core of the rotor is built with stacks of electrical steel laminations. The figure shows one of many lamination sets used. The rotor lamination has a larger number of slots than its corresponding stator lamination, and the number of rotor slots should be a non-integer multiple of the number of stator slots to prevent magnetic ...
Silicon steel has low hysteresis loss, and the laminated construction prevents eddy currents from flowing in the core, which dissipates power in the resistance of the steel. The efficiency of typical distribution transformers is between about 98 and 99 percent. [8] [9] Where large numbers of transformers are made to standard designs, a wound C ...
Thin laminations are generally used on high-frequency transformers, with some of very thin steel laminations able to operate up to 10 kHz. Laminating the core greatly reduces eddy-current losses One common design of laminated core is made from interleaved stacks of E-shaped steel sheets capped with I-shaped pieces, leading to its name of E-I ...
Direct bonding, or fusion bonding, is a wafer bonding process without any additional intermediate layers. It is based on chemical bonds between two surfaces of any material possible meeting numerous requirements. [1]

The energy dissipated is proportional to the area enclosed by the loop. To prevent them, the cores of AC electromagnets are made of stacks of thin steel sheets, or laminations, oriented parallel to the magnetic field, with an insulating coating on the surface. The insulation layers prevent eddy current from flowing between the sheets.
