What Is Electrical Steel?

Electrical steel, also known as silicon steel, lamination steel, or transformer steel, is a specific type of steel engineered to possess high magnetic properties.

Electrical steel is classified into two main types: non-oriented (NO) electrical steel and grain-oriented (GO) electrical steel.

Silicon Steel Performance Indicators

Low Core Loss

Core loss, often called iron loss, is a critical indicator of silicon steel performance. It measures the energy dissipated as heat due to the alternating magnetic fields in the material. The lower core loss, the higher the grade of electrical steel.

High Magnetic Flux Density

High magnetic properties of electrical steels are essential for energy conversion in motors. A strong magnetic field reduces the volume and weight of the iron core of the motor and transformer. It saves silicon steel sheets, copper wire, and insulating materials.

Stacking Factor

The stacking factor measures how effectively laminations can be stacked to form a core in transformers or motors. The surface is smooth, smooth and the thickness is uniform, which can improve the filling coefficient of the iron core.

Material Coating

Silicon steel surface insulation coating(such as oxide or varnish) reduces eddy current losses as they dissipate heat and improves motor adequate energy.

Different types of motor lamination materials

In addition to silicon steel, amorphous alloys, cobalt alloys, and nickel alloys are also suitable for motor laminations. Due to production costs and processing difficulties, nickel and cobalt alloys are not used in mass production. However, these materials have higher magnetic permeability and lower core losses than silicon steel.

Why choose us to use lamination steel for custom motor stator and rotor

Motorneo stamp motor rotor and stator laminations are made from 0.1 to 1 mm thin-gauge electrical steels.

We will use a silicon steel detector to test the silicon steel to ensure the physical and electromagnetic properties of the silicon steel.

Our comprehensive motor lamination services encompass stamping, laser cutting, stacking, winding, assembly, and even aluminum die-casting rotor, etc.

Obtained ISO/FDIS 9001:2008 and ISO/TS 16949 international certifications.

Silicon Steel FAQs

Silicon steel alloys, such as grain oriented electrical steel and non grain oriented electrical steel variants, are carefully chosen based on the specific requirements of the motor application.

Grain-oriented silicon steel, with its distinctive grain structure. This steel is used where high permeability is primarily oriented in one direction, such as transformers.

Non-oriented silicon steel, on the other hand, is more suitable for applications where the magnetic flux changes direction frequently, as seen in motors.

With cold rolled motor laminations differ; motor lamination steel has optimal magnetic properties, reduces energy losses, and improves magnetic flux distribution. This leads to motors that operate with higher efficiency and performance.

0.2mm silicon steel stamping is pricier due to its scarcity, precision demands, and unique properties. Thinner sheets minimize core loss, enhancing energy efficiency, but their production requires meticulous precision, often leading to higher manufacturing costs.
