About

N.C. Cheung is a researcher specializing in precision motion control, electric actuator design, and automated manufacturing systems, with a particular focus on developing innovative electromagnetic actuators for industrial applications. His work addresses fundamental challenges in high-precision robotic and manufacturing environments, where conventional mechanical drive systems often fall short. Cheung's most recognized contribution lies in advancing linear switched reluctance motor (LSRM) technology, demonstrating how improved mechanical structures can deliver the precise linear motion demanded by semiconductor manufacturing processes such as wire bonding and surface mount technology — areas where traditional ball-screw and belt-driven systems introduce unacceptable positioning errors. His 2006 paper on LSRM improvements has garnered 7 citations, reflecting meaningful influence within a specialized engineering community. Beyond linear motors, Cheung has championed variable reluctance actuators as viable proportional control devices, challenging the prevailing assumption that their nonlinear characteristics limit them to simple switching roles. His work in grasping applications and automated assembly machines demonstrates practical pathways for deploying these cost-effective, robust actuators in demanding manufacturing contexts. Collectively, his research offers engineers practical alternatives to conventional rotary motor-and-transmission systems, contributing to more direct-drive, compact, and accurate motion solutions across modern industrial automation.
