High-efficiency miniature linear actuators and micro stepper motors engineered to strict EU reliability standards.
Luxembourg has transitioned from a traditional heavy industry steel-based economy into an advanced engineering, space technology, and medical instruments hub. Key development centers like the Belval Research Portal, the Luxembourg Institute of Science and Technology (LIST), and the Luxembourg Space Agency (LSA) drive demands for micro-positioning components of absolute accuracy.
High-performance coreless motors and linear stepper motors play a foundational role in these emerging sectors. The lack of rotational iron losses in coreless configurations provides superior responsiveness, making them ideal for high-speed robotic grippers, surgical devices, and precision optics assembled in Luxembourg's advanced factories.
Why Luxembourgish R&D engineers opt for slotless, coreless micro-drive topologies for critical positioning loops.
Traditional electromagnetic motors rely on a rotor featuring copper coils wound around an iron core. This configuration results in "cogging torque" due to the magnetic attraction between the stator magnets and the rotor slots, which degrades positioning precision at slow speeds. Coreless DC and BLDC motors bypass this issue entirely by utilizing a self-supporting, basket-shaped skew-wound copper coil as the rotor.
By eliminating the iron core, we achieve extremely low rotor inertia, enabling ultra-fast acceleration and deceleration profiles. The absence of iron losses also leads to exceptional efficiency (often exceeding 85%), which is paramount for battery-operated medical devices and remote communication systems utilized in modern IoT industrial networks across Clervaux, Contern, and Esch-sur-Alzette.
| Parameters | Coreless Rotor Technology | Standard Cored Stator |
|---|---|---|
| Cogging Torque | Zero (Perfect Smoothness) | Present (Interrupts Slow Rotation) |
| Mechanical Time Constant | < 5 ms (Rapid Response) | > 15 ms |
| Power-to-Volume Ratio | High (Extremely Compact) | Moderate |
| Electromagnetic Interference | Low (Self-Shielding Layout) | High (High Iron Mass Inductance) |
Integrating lead screws directly onto micro stepper motors transforms rotational motion into high-precision linear displacement without secondary couplers. This minimizes backlash and reduces overall envelope dimensions.
For applications in smart glasses (such as active optical alignment) and laboratory auto-pipettes, our 10mm to 15mm permanent magnet (PM) linear stepper motors provide up to 160g.cm of holding torque and micron-level stroke control, ensuring long-term mechanical stability.
Under our guiding philosophy—Top Quality & Customization—our production facility employs automated winding, laser spot welding, and microscopic QC to ensure consistent excellence.
