About
Erik Hultman’s research sits at the intersection of industrial robotics and sustainable energy manufacturing, focusing on automating the production of large electrical machines for renewable energy systems. His primary contributions center on robotized cable winding—a technique that replaces manual, time-consuming stator winding in high-voltage, direct-drive generators used in wind, hydropower, and wave energy. Hultman developed the first fully automated cable winding process, including a specialized cable feeder tool and automated cable preparation equipment, validated through full-scale experiments on Uppsala University’s wave energy converter generators. His work also extends to robotized surface mounting of permanent magnets and 6-DOF positional calibration using proximity sensors, addressing critical automation challenges in large-machine assembly. With over 98 total citations across his top ten papers, Hultman’s research has directly advanced the feasibility of mass-producing wave energy converters and other renewable energy technologies. Notably, his 2012 paper on cable winding manufacturing remains a foundational reference, while his 2018 study validating the first fully automated stator cable winding process marks a key milestone. Hultman’s work demonstrates how robotic automation can reduce costs and increase production scalability, making renewable energy systems more competitive on the global market.
