Custom Electrical Steel Laminations Manufacturer in China
Electrical steel laminations are thin layers of specialized electrical steel that are used to construct the cores of transformers, electric motors, and generators. They are produced by a rapid stamping process. Usually, we produce silicon steel laminations thicknesses between 0.25 and 1 mm. We produce rotor and stator laminations and assembled stator and rotor lamination stacks.
Prototyping motor laminations
Laser cutting is a precise and efficient method that uses a high-powered laser beam to cut the steel sheets into the desired shape. This method produces clean edges and can be suitable for various types of laminations. However, it may not be suitable for thicker materials or complex shapes.
On the other hand, wire EDM involves using a thin wire to cut through the steel sheets, creating complex shapes with high precision. This method is ideal for thicker materials and intricate designs. Our EDM cutting capability is up to 1-micron tolerance.
Silicon Steel Laminations assemble
For assembling silicon steel laminations, we offer a range of stacking options to suit different requirements. And we ensure that our silicon steel laminations are assembled to the highest standards of quality and efficiency.
Interlocking is a popular method that involves placing individual laminations on top of each other in a specific order to create a stack.
Bonding is another option, where an adhesive material is suitable for bonding the laminations together. This method can provide additional stability and reduce vibration in the final product.
Finally, welding is a more permanent method that involves fusing the laminations together using heat or pressure. This method is ideal for applications that require high strength and durability.

motor lamination steel grades
There are two main grades of electrical steel: grain-oriented (GO) and non-oriented (NO).
Non-oriented Electrical Steel
Non-oriented electrical steel has a random crystal orientation and is better suitable for smaller electrical components like motors and generators.
Grain-Oriented Electrical Steel
Grain-oriented electric steel has a highly directional crystalline structure that allows it to exhibit superior magnetic properties in the direction of its grain. This makes it ideal for use in large power transformers.

Other motor laminations materials
In addition to lamination steel, nickel alloy, and cobalt alloy are also suitable for motor laminations. These materials have higher magnetic permeability and lower core losses compared to silicon steel.
Nickel alloys, like permalloy, are commonly suitable in high-frequency applications, while cobalt alloys, like vanadium-fermenter, are suitable in high-temperature applications.
However, these materials are more expensive and harder to work with than silicon steel, making them less common in mass-produced motors. Nevertheless, they are a good choice for specialized applications where high efficiency and performance are critical.
electrical Steel Laminations FAQs
Electrical steel laminations are typically very thin, with a thickness ranging from 0.18mm to 0.5mm. This thinness is necessary to minimize eddy current losses and increase the magnetic permeability of the steel.
The laminations are typically made by stacking multiple layers of thin electrical steel sheets and then punching holes through them to create the required shape for the electrical component.
The thickness of the laminations may vary depending on the specific application, but in general, they are as thin as possible while still maintaining the required electrical and magnetic properties.
Cold rolled motor laminations steel are widely suitable in various industrial applications, including HEV and EV drives, new energy vehicles, aerospace, and defense applications.
In HEV and EV drives, electrical steel laminations are suitable for making the stator and rotor cores of electric motors due to their high magnetic permeability, low core loss, and low eddy current losses.
For industrial applications, they are suitable for transformers, generators, and other electrical equipment.
In the aerospace and defense industries, electrical steel laminations are suitable in motors, generators, and power conversion systems due to their high efficiency, low weight, and compact size.
Therefore, it is clear that electrical steel laminations have a wide range of applications in various industries, making them an essential component in modern-day technology.
Silicon steel laminations contain between 2% and 4% silicon.
The manufacturing process involves multiple steps, including stamping, annealing, and coating.
During the stamping process, the electrical steel is cut into precise shapes and sizes that will fit together to form the completed core.
Annealing involves heating the steel to high temperatures and then cooling it slowly to improve its magnetic properties.
Finally, the coating prevents corrosion and improves the efficiency of the core.
Electrical steel sheets are an integral part of every motor. These laminations are crucial components of these electrical devices as they reduce energy loss during the process of converting electrical energy from one form to another.
Magnetic properties: Silicon steel laminations exhibit excellent magnetic properties, making them ideal for use in electrical equipment such as transformers and generators.
Electrical conductivity: These laminations have high electrical conductivity, which means that they are efficient at conducting electricity and transmitting electrical current without generating excessive heat.
