What Is the Riveting Process?
Our riveting process is a motor lamination stack bonding technique crucial in creating strong and durable connections between a number of thin electrical steel laminations.
It involves using a rivet—a cylindrical metal fastener—that stacks the motor stator lamination or rotor lamination together by deforming its end to secure them in place.
Riveting is a versatile method employed across various industries to ensure sturdy connections that can withstand mechanical stress, vibrations, and other forces.
Riveting Capabilities For motor Lamination

The rivet is inserted into this punched hole, protruding one end from the material’s surface. By applying force or pressure to the exposed end of the rivet, often through hammering or a specialized riveting machine such as a pneumatic hammer, the rivet’s end is deformed, creating a head larger than the hole.

This deformation causes the rivet to expand radially, compressing the materials tightly. As the rivet compresses, it creates friction between itself and the motor laminations, resulting in a secure and permanent bond.
Advantages of riveting Motor Lamination Stacks
The riveting process offers several distinct advantages, making it a preferred method of joining materials in various industries.
Strength and Reliability
The mechanical interlock created by the deformed rivet ensures a robust joint that can withstand substantial loads.
Permanent Connection
Once riveted, the connection is permanent. Rivets don’t rely on adhesives or heat to maintain their bond, ensuring the joint remains secure over time.
Resistance to Vibration and Shock
Riveted joints are highly resistant to vibrations and shocks, making them suitable for transportation, construction, and aerospace applications.
Ease of Inspection
Riveted connections are visible and easy to inspect for quality and integrity, allowing for quick assessments of joint reliability.
Cost-Effective
The riveting process is often more cost-effective than other methods like welding or brazing. It doesn’t require expensive equipment or consumables and can be performed quickly.
Safety
Riveting doesn’t involve open flames, which can contribute to a safer working environment, mainly when flammable materials are present.
Suitable for High-Performance Applications
The reliability and strength of riveted connections make them suitable for high-performance applications, such as industrial machinery, electric vehicles, robotics, and aerospace, where motors are subjected to demanding conditions.
Riveting Laminations Stacks FAQs
In addition to the riveting process, several other motor stacking processes play a crucial role in the manufacturing of electric motors.
Cleating involves the insertion of cleats or tabs between individual motor stator lamination to provide additional stability and alignment within the motor core.
Welding involves laser and TIG+MIG welding, fusing the laminations using heat or pressure.
Gluing lamination is the application of adhesive or glue to bond individual laminations together to form the core of an electric motor. The glue is typically a specialized epoxy or resin.
Self-bonding property is through pressure and heat applied during the motor lamination stack assembly.
The stator and rotor lamination stacking process involves meticulously arranging individual laminations made of specialized electrical steel into precise configurations for electric motors and generators.
For the stator, laminations with slotted cores are aligned and stacked to form the stationary part of the motor. In the rotor case, lamination stacking to construct the rotating component, often focusing on achieving balanced mass distribution.
The stacked laminations are securely pressed, clamped, or riveted to ensure cohesion, optimal alignment, and minimal air gaps, creating a robust magnetic circuit.
