Customize Electric Steel Laminations Of Glue-Dot Bonding
Glue-dot bonding enables precise customization of stator and rotor lamination shapes and sizes, facilitating optimal motor performance and reducing energy consumption. The motor application areas for customized electric steel laminations with glue-dot bonding are vast, ranging from small electric motors in household appliances to larger industrial applications such as electric vehicles, drones, wind turbines, and power generators.
Our Motor Lamination Stacks Glue FASTEC Capabilities
The core lamination stacking provides the magnetic circuit for the motor, enabling the conversion of electrical energy into mechanical motion, Our laminations stack glue FASTEC capabilities offer high-speed and precision gluing solutions for motor laminations. Compared with the traditional dowel cores process, this process produces motor iron cores that have less iron loss (eddy current loss and hysteresis loss). The iron loss reduction by 10% or more, means less energy loss.
The stamping or laser and wire-cutting laminations need cleaning and preparation before gluing. This may involve removing any dirt, oil, or other contaminants that could interfere with the bonding process.
A suitable insulating adhesive or bonding agent is applied to the surfaces of the laminations. The adhesive is usually applied using a spray or brush, and care is taken to ensure that the adhesive is applied evenly and consistently across the surface.
Using a hydraulic press, a mechanical press, or other suitable equipment, one can effectively perform this step.
The adhesive needs to be cured or allowed to dry to form a strong bond. This can be done at room temperature, or the laminations can be heated to speed up the curing process.
Benefits Of Gluing Bonding Motor Core Laminations
Bonding motor core laminations using adhesives or glues offers numerous benefits in the manufacturing of the electric motor industry. Some of the key advantages include:
Reduced Noise and Vibration
Gluing motor core laminations helps to eliminate any air gaps between the laminations, which reduces the chances of vibrations and the associated noise, leading to a quieter motor.
Better Thermal Conductivity
The adhesive, serving as a thermal conductor, enhances heat dissipation from the core, which permits the motor to endure higher temperatures without core damage.
Enhanced Mechanical Strength
The adhesive enhances the mechanical strength of the core, preventing shifting or deformation under high loads or during operation by bonding the electrical steel substrates.
Improved Efficiency
By eliminating air gaps you can ensure that the magnetic flux effectively channels through the core, enhancing magnetic properties and allowing the motor to operate with less energy loss.
Cost Savings
Gluing the laminations together eliminates the need for additional mechanical fasteners or mechanical clamping systems, which can simplify the assembly process and reduce manufacturing process costs.
Corrosion Prevention
By encapsulating the laminations with an adhesive, the motor components are better protected against moisture and corrosive substances, extending their lifespan and reliability.
Quality Control For Adhesive Stator And Rotor Laminations
- Conduct thorough checks on the adhesive material before application, ensuring it meets specified standards for viscosity, curing time, and compatibility with the laminations.
- Perform adhesion tests to ensure the bond strength meets or exceeds the required specifications.
- Subject the bonded laminations to vibration and stress tests to ensure they can withstand the rigors of motor operation.
- Conduct visual inspections to check for any defects or imperfections in the adhesive bond.
- Verify that the bonded laminations meet the required dimensional tolerances.

Laminations Gluing Bonding FAQS
Traditional gluing bonding stator and rotor methods often involve applying a continuous layer of adhesive across the entire surface of the laminations.
Glue-dot bonding, on the other hand, uses small dots of adhesive, which can provide more precise control over the bond area and reduce the risk of excess adhesive interfering with the motor’s performance.
Various types of adhesives can be used in glue-dot bonding, depending on factors such as the material of the laminations, desired bond strength, and environmental conditions. Commonly used adhesives include cyanoacrylates, epoxies, and hot melt adhesives.
Adhesive dots are typically applied using specialized equipment, such as a dispensing machine, which can accurately deposit the adhesive dots in the desired pattern and quantity.
Glue-dot bonding can be used with a wide range of materials commonly used for motor laminations, including silicon steel and other metallic alloys. However, the suitability of glue-dot bonding for a specific application depends on factors such as the type of adhesive used, the surface characteristics of the laminations, and the required bond strength.
In addition to the rotor and stator lamination gluing bonding technology, we offer self-bonding, welding processes (laser welding, tig welding, mig welding), riveting, cleating, and interlocking techniques used to bond together the laminations.
