The FSN lightweight type is Laifual Drive’s specialized solution for weight-sensitive applications. Through structural optimization and advanced material engineering, the FSN Series achieves a lightweight profile without compromising performance. It delivers the same high precision, torque capacity, and rigidity as our standard models, making it the ideal choice for dynamic systems where reducing inertia and overall mass is critical.
FSN Lightweight
FSN Harmonic Drive Unit
Key advantages of the FSS unit include:
-
Ultra-Lightweight Design: Significantly reduced weight compared to standard series, helping to lower the total mass of the robotic joint or automation equipment.
-
Uncompromised Performance: Unlike traditional lightweight solutions that may sacrifice durability, the FSN Series maintains the same torque output, stiffness, and transmission accuracy as standard Laifual products.
-
High Power Density: Offers an exceptional torque-to-weight ratio, allowing for the design of faster, more agile, and energy-efficient machinery.
-
Low Moment of Inertia: The reduced mass contributes to lower start-up torque and faster acceleration/deceleration response.
