About

Ju Lee is a prominent electrical engineer whose research spans advanced motor design, electromagnetic field computation, and robotics actuation systems. With a career dedicated to pushing the boundaries of electric machine technology, Lee has made significant contributions to both theoretical frameworks and practical applications in motor engineering. Lee's most notable work centers on multi-degree-of-freedom (multi-DOF) spherical motors, pioneering designs that eliminate the need for conventional gear systems in robotic joints. His research on double air-gap spherical motor configurations and electromagnetic field computation using sigmoid-based interpolation methods has helped lay the groundwork for next-generation humanoid and robotic eye systems, earning over a dozen citations across related studies. More recently, Lee has directed his expertise toward high-efficiency permanent magnet synchronous motors (PMSMs), including spoke-type configurations for hybrid and electric vehicles — his most cited work with 22 citations — and novel slotless motor designs tailored for collaborative robots, addressing real-world manufacturing constraints. Across his body of work, Lee demonstrates a consistent ability to bridge fundamental electromagnetic theory with industry-relevant engineering solutions, making his research particularly valuable to students and practitioners working at the intersection of motor design, robotics, and electromechanical systems.
