What Is Electrical Steel?

Electrical steel, called silicon steel, is a specialized material crafted to optimize magnetic properties. Its role in motor lamination manufacturing is pivotal as it significantly impacts motor efficiency.

Different types of motor lamination steel alloys, grain-oriented and non-oriented electrical steel, are carefully selected based on the application’s requirements.

These alloys ensure that the motor cores are designed to function optimally within specific contexts.

Silicon Steel Performance Indicators

Lamination steel is crucial for various electric motor devices, especially transformer cores. The leading performance indicators of silicon steel include:

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.

Customize Electrical Steel Laminations Application

Various motor devices apply silicon steel due to its unique magnetic and conductive properties. Here are some critical applications of silicon steel:

Industrial motors

High-speed pump



Automotive (H) EV vehicle


Power tools

Household appliances

Wind Generators

Electric Motor

Different types of motor lamination materials

In addition to silicon steel, cobalt 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.

Electrical Steel FAQs

Electrical 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 electrical 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.

Our experts work closely with clients to choose the right silicon steel alloy materials based on specific needs and industry standards. This collaborative approach ensures that the selected alloy optimizes motor efficiency while maintaining cost-effectiveness.

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.
