What Are the Different Types of Silicon Steel Lamination?

Silicon steel laminations, also known as electrical steel laminations, are used in the cores of electrical transformers, inductors, generators, and electric motors. They are made from thin and flat pieces of silicon steel that are stacked and insulated to form the core of the device. However, to ensure optimal performance from your electric devices, it’s important to understand the types of silicon steel lamination materials. Here’s a breakdown of several common types:

Silicon Steel Lamination Types You Must Know

Silicon steel lamination can be divided into different types in terms of grain orientation, manufacturing process, and shapes. Let’s explore together.

1. Grain Orientation

Grain Oriented Silicon Steel Lamination

These are made from silicon steel that has been specially processed to have a preferred direction of magnetization. This results in lower core losses and higher magnetic permeability in the direction of the grain, making it ideal for applications where the magnetic field is constant in one direction, such as in power transformers.

Non Grain Oriented Silicon Steel Lamination

These are made from silicon steel that has uniform magnetic properties in all directions. This makes them suitable for applications where the magnetic field can vary in direction, such as in distribution transformers and electric motors.

2. Manufacturing Process

Hot Rolled Silicon Steel Lamination

It is produced by hot rolling process, which involves heating the steel to a high temperature and then rolling it into a thin sheet. Then the hot-rolled silicon steel is shaped into the desired laminated shape.

Cold Rolled Silicon Steel Lamination

It is produced by the cold rolling process, which helps to align the silicon crystals in the steel. The silicon steel is then shaped into the desired laminated shape.

3. Shape

According to the shape, silicon steel lamination can be divided into EI shape, UI shape, C shape, O shape, rectangular shape, etc.

EI Shape

The “EI” designation refers to the shape of the lamination, which is formed by stacking two types of laminations: E-shaped and I-shaped. This shape is designed to provide a path for the magnetic flux to flow through the core, which is essential for the operation of the device.

UI Shape

The “UI” designation refers to the shape of the lamination, which is formed by stacking two “U” shaped pieces of silicon steel with an “I” shaped piece in between. This shape is chosen because it provides a good balance between magnetic flux and electrical insulation, and it is also relatively easy to manufacture.

C Shape

“C” refers to silicon steel lamination stacked in a C shape. It can effectively reduce magnetic flux leakage and reduce the loss of induced electromotive force, making the transformer more efficient. The C-shaped stack can also reduce the loss and noise of the core and improve the working performance of the transformer. C-type stacked type is often used in some transformers with higher requirements.

O Shape

“O” means that silicon steel sheets are stacked in an O shape. It can make the harmonic waveform of the transformer closer to the sinusoidal waveform, reduce the harmonic content, and improve the working stability of the transformer. In addition, the O-shaped lamination can also reduce the harmonic loss and noise of the transformer and improve the working efficiency of the transformer.

Rectangular Shape

Rectangular type refers to silicon steel lamination stacked in a rectangular shape. It can make the core short-circuit loop of the transformer shorter, reduce the leakage loss, and improve the efficiency of the transformer. Therefore, the rectangular silicon steel lamination is suitable for some transformers with higher requirements and can effectively increase the rated capacity of the transformer.
