Direct Drive Applications
Medical & Life Sciences — Direct Drive Applications
Medical equipment and life-science instruments require clean, smooth, low-noise and maintenance-free precision motion, and continue to move toward miniaturization. Ironless linear motors deliver smooth positioning contactlessly and without cogging, while UPR printed-circuit-board lightweight motors serve as low-inertia rotary axes — supporting surgical robots, lab automation and diagnostic and analytical instruments.
Drive Challenges in Medical & Life SciencesDrive challenges in medical & life sciences
Medical equipment and laboratory instruments impose strict requirements on cleanliness, smoothness, precision and reliability.
Clean & Particle-FreeClean & Particle-Free
Surgical and laboratory environments are sensitive to contamination. Direct-drive motors have contactless transmission and are wear-free, avoiding lubricant and wear-particle contamination; ironless linear motors have a clean structure that benefits clean design.
Smooth, Low-Noise MotionSmooth, Low-Noise Motion
Surgical positioning and diagnostic measurement require extremely low noise and no vibration. UPLplus ironless linear motors have no cogging force or ripple force and move extremely smoothly; UPR has no cogging and extremely low load ripple, ensuring smooth and quiet operation.
Precision MiniaturizationPrecision Miniaturization
Medical equipment continues to miniaturize. UPLplus offers +42% force-to-mass ratio with low moving mass, compact and lightweight; UPR is a printed-circuit-board lightweight motor with low profile and low inertia, ideal for space-constrained medical and laboratory instruments.
Maintenance-Free & ReliableMaintenance-Free & Reliable
Diagnostic and analytical instruments require 24-hour continuous operation. Direct drive is contactless, wear-free and maintenance-free with high reliability; UPR is contactless and wear-free, ensuring long-term consistent accuracy and lifetime.
