Precision, Smooth Operation, and Thermal Stability as Key Performance Factors
In sensitive applications such as robot-assisted surgery or implantable systems, even minimal imbalance or vibration can compromise accuracy. At the same time, drives must remain thermally stable during continuous operation to ensure patient safety and long-term reliability.
High-quality lamination stacks with optimized magnetic properties play a decisive role in minimizing magnetic losses, improving efficiency, and reducing heat development. This is particularly critical for cardiovascular systems, implantable devices, and motorized endoscopic solutions, where even small efficiency losses can present risks.
Facts
- Backlack bonding enables high-precision, low-vibration miniature drives
- Segmented stators increase efficiency, reproducibility, and design freedom
- Ultra-thin special materials minimize magnetic losses and increase energy efficiency
Innovative Manufacturing and Bonding Technologies for High-Performance Stators and Rotors
The demands placed on electric drives in medical technology continue to rise. Robotic assistance systems, surgical hand tools, blood pumps and minimally invasive instruments require compact miniature drives that deliver maximum precision, smooth operation and energy efficiency while generating minimal heat. Conventional manufacturing methods are increasingly reaching their limits — especially when extremely small geometries, tight tolerances, and the highest requirements for magnetic performance are involved.
Advanced production and stacking technologies for lamination stacks are therefore becoming essential to meet both technical and regulatory standards in modern medical applications.

Backlack Bonding for Structural Integrity and Reduced Vibration
A key technology is the Backlack jointin which individual slats are glued together over their entire surface. In contrast to conventional welding or punching stacking processes, highly stable, dimensionally accurate sheet metal packages are produced with significantly reduced vibrations and noise emissions.
The increased structural strength also allows higher winding tension and faster winding speeds, improving copper fill factors and enabling tighter air gaps between stator and rotor. The result is enhanced power density and improved overall efficiency — decisive advantages for compact, high-performance medical drives.
Segmented Stators for Greater Flexibility and Efficiency
Segmented stators offer further technological advantages. Individual segments can be manufactured and wound separately with high precision before being assembled into a complete stator. This improves reproducibility, increases process speed, and enables higher copper fill factors — a critical parameter in miniaturized motors.
Segmentation also supports ultra-compact designs for minimally invasive instruments while optimizing the magnetic characteristics of the stator. The combination of efficiency, flexibility, and process stability enhances both performance and safety in demanding medical applications.
Advanced Materials and Automated Precision Manufacturing
Modern medical devices increasingly rely on specialized materials such as cobalt-iron alloys or ultra-thin electrical sheet below 0.1 mm. These materials significantly reduce magnetic losses but require exceptional punching precision and process stability.
Automated manufacturing systems, digital measurement technologies, and digital twins ensure consistently high edge quality and full traceability — an indispensable requirement in highly regulated medical environments. At the same time, scalable production concepts allow efficient manufacturing of small and medium-sized series while maintaining the option for future volume expansion.
Applications Across the Medical Technology Spectrum
High-precision stators and rotors with optimized lamination stacks are used in:
-
High-speed surgical hand tools
-
Robotic assistance systems
-
Blood pumps and cardiovascular support systems
-
Electrically driven dental devices
-
Compact motors for endoscopy and microfluidic systems
In each of these applications, the combination of backlack bonding, segmented stators, advanced materials, and automated production processes enables a new level of performance in terms of precision, smooth operation, and energy efficiency.
Conclusion
Medical technology requires increasingly compact, quiet, and energy-efficient drive systems. Innovative manufacturing technologies for lamination stacks provide the foundation for this next generation of performance.
Through full-surface bonding, segmented stator design, advanced materials, and highly automated production processes, modern stators and rotors achieve exceptional precision, thermal stability, and power density.
Thus, modern manufacturing technologies form the basis for the next generation of medical devices — more powerful, safer, and more sustainable.
