Motion Control Requirements for Medical Instruments

Medical equipment motion control runs the gamut from electric wheelchair motion to heart assist pumps. This article will focus on the segment consisting of medical laboratory instruments. Even in this segment, motion control ranges from precision liquid handling and dispensing, to sample- handling robotics and automated sample storage and retrieval systems. We’ll delve into precision liquid handling and dispensing and related functions, and the interaction between the mechanical system and the motion control system. High-pole-count permanent magnet AC servo motors can simplify system design and improve system performance and reliability when mated with control systems capable of bringing out their full potential.
