Lower Losses
Compared to interlocking and welding, bonding has not short cuts between the single sheets. Better magnetical properties and lower losses are the result.
-
Reduces Noise
The single sheets are glued together tightly which reduces vibration and noise. A good approach to address the higher requirements.
-
Improves Thermal Conductivity
The full area bonding improves thermal conductivity within the stack because Bonding varnish/Backlack has a better thermal conductivity than the air we have from interlocking or welding.

Bonding varnish/Backlack - the joining technology for perfect lamination stacks!
The stator and rotor cores of electrical machinery are manufactured using thin laminations stacked together in order to minimize eddy current losses. There are several ways to join these laminations, and the most efficient way is to use Backlack.
Enhanced Structural Integrity
Bonding laminations together creates a unified and robust structure, minimizing the risk of mechanical failure and ensuring long-term reliability.
Reduced Eddy Current Losses
Proper stator and rotor core stacks bonding minimizes eddy current losses, optimizing energy efficiency and reducing heat generation.
Improved Magnetic Energy Transfer
Bonded laminations contribute to efficient magnetic energy transfer, enhancing the motor's overall performance and energy efficiency.
Thermal Stability
The bonded structure enhances thermal stability, crucial for motors operating in variable temperature environments.
Vibration Reduction
The bonding process reduces vibrations within the motor, leading to quieter operation and extended lifespan.
Cost-Effective
It is a cost-effective solution to reducing the need for additional bonding and enhancing overall motor performance.
Materials Used In Motor Bonding Lamination Stacks
Silicon steel is regarded as an excellent option for electrical steel lamination prototypes. It not only has good corrosion resistance, is lightweight and has high strength, but its good conductivity ensures efficient application in complex electrical systems.
Non-oriented silicon steel materials with a thickness of 0.10/0.20/0.35MM are also very suitable for making prototype laminations due to their excellent tensile strength, durability and excellent electrical properties, showing a high degree of applicability.
As for nickel alloys, their high corrosion resistance, excellent electrical conductivity and relatively low cost make them ideal materials for prototyping laminates, which, combined with their ease of forming, further enhances their usefulness in this field sex.
