About

Jun-Hyuk Choi is a leading researcher in the design and control of high-performance brushless DC (BLDC) motors, with a specialized focus on compact, high-torque actuators for robotic systems. His most cited work, “Design of axial flux permanent magnet brushless DC motor for robot joint module” (27 citations), pioneered a slim axial flux topology that delivers exceptional torque density—critical for space-constrained robot joints. Choi’s contributions extend to efficiency optimization, as shown in his 2014 study on control schemes for slim-type BLDC motors (12 citations), which addresses the growing demand for miniaturized actuators in home appliances and vehicles. He has also advanced micro-motor technology, with papers on ultra-small BLDC motors (7 citations) for medical and automation applications, and on entertainment robot motor development (9 citations). By combining numerical analysis with analytic modeling, Choi has enabled practical, high-torque solutions that bridge the gap between theoretical motor design and real-world robotic integration. His work remains foundational for engineers seeking to maximize power density in next-generation, slim-profile actuation systems.
