    • Concentric-Coil Distributed Winding Design for Large Direct-Drive Fully Superconducting Machines 

      Lin, Jiaxi; Liu, Dong; Wu, Yingjun (IEEE, 24.02.2023)
      Fully superconducting generators (FSCGs) use superconducting wires for both the field and armature windings to reach a high torque density for wind turbine applications. The AC armature winding of an FSCG design mostly ...

    • Design and Manufacturing of a Modular Low-Voltage Multi-Megawatt High-Speed Solid-Rotor Induction Motor 

      Kurvinen, Emil; Di, Chong; Petrov, Ilya; Nerg, Janne; Liukkonen, Olli; Jastrzebski, Rafal P.; Kepsu, Daria; Jaatinen, Pekko; Aarniovuori, Lassi; Sikanen, Eerik; Pyrhönen, Juha; Sopanen, Jussi; Pyrhönen, Olli; Niemelä, Markku; Kangasmäki, Toni (IEEE, 26.05.2021)
      High-speed solid-rotor induction machines (HSIMs) are popular within high-speed applications because of their high rotor structural integrity and their fairly well-established manufacturing process guaranteeing high quality ...

    • Design Aspects of a Compact Variable Reluctance Resolver 

      Abramenko, Valerii; Petrov, Ilya; Pyrhönen, Juha
      Proceedings : IEEE international electric machines and drives conference (IEEE, 04.07.2025)
      Variable reluctance (VR) resolvers are used in electrical drives for position and speed feedback. Their winding-free rotors make them particularly robust and reliable. One example of their application is in electric ...

    • Energy transition changing land use – estimating large-scale PV and Power-to-X potential of present peat production areas 

      Räisänen, Otto; Vilppo, Julius; Haapaniemi, Jouni; Supponen, Antti; Karjunen, Hannu; Repo, Sami; Lassila, Jukka (IEEE, 20.10.2022)
      Due to EU Climate policies the use of peat as an energy source is winding down. In Finland alone there was approximately 900 km 2 of active peat production area in 2021 and it has been proposed that these large and otherwise ...

    • Investigation of a Direct Liquid Cooling System in a Permanent Magnet Synchronous Machine 

      Petrov, Ilya; Lindh, Pia; Niemelä, Markku; Pyrhönen, Juha; Scherman, Eero; Wallmark, Oskar (IEEE, 08.10.2019)
      A high demand for electrification of the transport sector has resulted in a need to provide compact and reliable electric power trains where the electric machine is a key element. The cooling system has a strong impact on ...

    • Linear Variable Reluctance Resolver With a Modular Design 

      Abramenko, Valerii; Petrov, Ilya; Pyrhönen, Juha
      Proceedings : IEEE international electric machines and drives conference (IEEE, 04.07.2025)
      This paper presents the design and analysis of a linear modular variable reluctance (VR) resolver for precise position sensing in linear motion systems. The resolver features a modular stator with paired sine and cosine ...
