About

Hyun Jang Shin focuses on the acoustic and electromagnetic optimization of permanent magnet motors for robotic joints. His core research addresses the critical challenge of noise reduction in compact, high-performance actuators. Shin’s major contributions lie in systematically identifying and simulating the three primary noise sources in these motors: rotor imbalance, aerodynamic turbulence from the rotator, and electromagnetic force harmonics. His work on "Acoustic FEA Analysis and Modification for Robot Joint BLDC Motor" (2017) demonstrates a practical application of this approach, where he used coupled electromagnetic, modal, and acoustic finite element analyses to pinpoint a 3500 Hz electromagnetic force as the root cause of abnormal noise. This methodology, further detailed in his 2018 paper, provides a robust simulation framework for engineers to preemptively address noise during the design phase. While his citation counts are currently modest, his targeted, simulation-driven approach is directly relevant to the growing field of quiet, high-torque-density robotics, offering a clear, replicable path for motor refinement in precision applications.
