About

E. J. Gudefin’s research centers on the electromechanical design and theoretical foundations of reluctance step motors—specialized electric machines used for precise motion control. His major contributions lie in advancing the structural understanding of these motors, particularly through his development of a “Structures Theory” that clarifies how the number of phases and rotor teeth interact to determine step resolution. Gudefin’s most cited work (1995, 7 citations) systematically analyzes conventional motor architectures, establishing the mathematical constraints governing step counts. He later extended this into a generalized theory (2002, 3 citations) that introduces dissymmetrical stator designs, a novel approach that dramatically expands the achievable range of steps per revolution—potentially enabling any integer value. While his citation counts are modest, Gudefin’s work is notable for its theoretical rigor and practical ambition, offering engineers new pathways to customize motor performance for applications requiring high precision or unusual step sequences. His research remains a specialized but valuable reference for those exploring non-standard reluctance motor topologies.
