Capabilities Of Glue Bonding Stacks For Electric Motor Laminations
Glue fastening is a unique mass-production adhesive technology that revolutionizes bonding motor stator and rotor laminations. This innovative method involves applying glue that securely unites laminations, forming a seamless and robust motor core.
We can stack motor lamination by gluing bonding processes (such as DotBond® and FullBond®) according to customer requirements. Whether it is through built-in tools or manual operation, it is a process.
Our Glue FASTEC® core produces less iron loss (eddy current loss and magnetic losses) than other magnetic core bonding technologies(Reduces iron loss by more than 10%).
Since our stacking is done by gluing, it can also be used for very thin metal sheet products.
We used a shrink-fitting compression test bench, and the effect on core losses was studied in stators fastened with interlocks and with Glue Fastec® at different compression stress conditions, with and without insulation. The glued stator increased stiffness 9.8 (±0.6) times compared to the interlocked stator.
Advantages Of Bonding Rotor And Stator Laminations
Enhanced Bonding Strength
Glue bonging ensures a robust bond between laminations. It is suitable for stacking thin/hard materials.
The adhesive layer effectively keeps the vibration at rotation low, contributing to quieter electrical machines operation, and smooth stacking reduces wind noise.
Improved Heat Dissipation
The adhesive bonding process aids efficient heat transfer across laminations and good motor cooling performance.
This process allows for intricate and customized electric machine designs that may not be achievable with traditional stacking methods.
Minimum Core Loss
The absence of additional mechanical fasteners reduces iron loss and heat generation, increasing motor efficiency.
Flexibility with Materials
Glue fastening is compatible with motor lamination materials like electrical steel and alloys.
Applications Of Glue Bonding Lamination Stacks
Glue fastening in electric motor stator core manufacturing is used in all sectors and a wide range of applications. Here are some applications:
Automotive Electrification: Glue bonding is ideal for manufacturing electric vehicles (EV) and hybrid vehicle motor cores, ensuring reliable and efficient performance.
Appliance Motors: Home appliances benefit from glue fastening’s quiet operation, vibration reduction, and improved magnetic properties and energy efficiency.
Industrial Automation: Glue fastening is employed in various industrial motors, enhancing durability and allowing for customized core designs.
Renewable Energy: Motors used in wind turbines and solar tracking systems benefit from adhesive bonding’s resistance to environmental conditions.
Laminations Stacks FAQs
Laminated electrical steel cores, as implemented in electric motors, were manufactured by applying various stacking processes.
Self-bonding property is through pressure and heat applied during the motor lamination stack assembly.
In addition, welding techniques like Laser Welding, TIG (Tungsten Inert Gas), and MIG (Metal Inert Gas) use thermal stress, electric arcs, and consumable electrodes to fuse laminations.
Our selection of adhesive bonding materials takes into account curing speed, bond strength and toughness. Usually used imported glue (such as epoxy resin) in line with the H class standard, temperature resistance up to 120-200 degrees.
Glue fastening is suitable for high-volume production, provided that the adhesive application process is efficient and streamlined. Working with our experience, we can ensure consistent adhesive application and quality control is essential.
The strength of a glue bond uses various testing methods, including lap shear testing, peel testing, and tensile testing. These tests measure the adhesive’s ability to withstand different types of forces, providing insights into its reliability and durability for specific applications.
