About

Motomichi Ohto is a researcher specializing in advanced motor drive systems and control technologies, with a particular focus on interior permanent magnet (IPM) motors and sensorless control methodologies. His most recognized contributions center on the innovative fusion of motor design and control engineering — a paradigm that demonstrates how deliberately co-designing hardware and control algorithms can unlock entirely new application possibilities. Ohto's most impactful work explores saliency-based sensorless drive systems for IPM motors tailored specifically to robot vehicle applications. Rather than adapting existing motor designs to control strategies, his approach advocates for purpose-built motor configurations that inherently satisfy both mechanical and control requirements, enabling reliable position estimation without physical sensors. This work, cited over two dozen times across closely related publications from 2007 and 2008, has contributed meaningfully to the fields of robotics, electric drives, and embedded motion control. His research is particularly valuable to engineers and students working at the intersection of electromagnetic machine design and modern control theory, offering a compelling demonstration that interdisciplinary thinking — bridging magnetics, mechanical systems, and signal processing — can yield practical, application-ready solutions in autonomous and robotic platforms.
