Motor lamination stacking is a crucial aspect in the production of electric vehicle motors, ensuring efficient and reliable performance.

Interlocking, a method where laminations fit together seamlessly, minimizes energy loss and enhances magnetic properties.

Laser welding ensures precision by fusing laminations with minimal heat impact. TIG (Tungsten Inert Gas) welding offers a clean and precise alternative, while MIG (Metal Inert Gas) welding provides efficiency in mass production.

Riveting involves securing laminations with rivets, ensuring structural integrity. Cleating, a method where laminations are stamped with protrusions, facilitates interlocking. Bolt stacking involves using bolts to hold laminations together, offering flexibility in disassembly.

The epoxy powder coating method involves applying an insulating layer of epoxy powder to the laminations, creating a robust barrier against corrosion, moisture, and wear. The electrostatic application process ensures even coverage, promoting uniform protection.

Epoxy coatings are known for their high dielectric strength, crucial for insulating motor components. Additionally, epoxy’s thermal resistance enhances the motor’s efficiency by withstanding elevated temperatures during operation.

This coating not only safeguards the motor against environmental factors but also contributes to the longevity and reliability of electric vehicle propulsion systems.

E-mobile Laminations FAQS

Laminations help reduce eddy current losses, which can occur when a magnetic field induces currents in the motor’s metallic components. This, in turn, enhances the overall efficiency of the electric motor.

Motor laminations are utilized in various industries beyond electric vehicles. They are integral components in automotive, home appliances, HVAC systems, industrial machinery, aerospace, rail transportation, and renewable energy applications.

Amorphous lamination offers significant benefits for new energy vehicles, enhancing efficiency and performance. With lower core losses and improved magnetic properties compared to traditional silicon steel, amorphous lamination contributes to increased energy efficiency, reduced heat generation, and overall improved sustainability in electric vehicle propulsion systems.

New energy vehicles often use axial flux motor laminations due to their compact design and improved power density. Axial flux motors offer a high torque-to-weight ratio, enabling efficient power delivery in electric vehicles. Their compact size and lightweight nature make them well-suited for applications with limited space, enhancing overall vehicle performance.

Self-adhesive technology streamlines electric vehicle motor assembly, eliminating the need for mechanical fasteners. This enhances production efficiency, reduces weight, and allows for more flexible and compact motor design in the automotive industry.


Flat wire motors offer compact design, high torque density, and superior heat dissipation, making them ideal for new energy vehicles. Their efficient performance and low profile enable enhanced powertrain integration and increased vehicle range. With advancements in electric vehicle technology, flat wire motors are poised to play a crucial role in shaping the future of transportation.

The thickness of laminations significantly influences motor performance. Thinner laminations of various motor types like DC and AC, synchronous and asynchronous, permanent magnet and induction, and axial flux, reduce core losses, enhancing overall motor efficiency.
