Analysis of Losses and Radial Vibration in a PM Synchronous Machine with Physical Modularity
Mellerud, Runar (Master thesis, 2021)En ModHVDC-generator er en spesielt lukrativ løsning for havvind ettersom den bidrar til et redusert antall komponenter i systemet og samtidig øker tilgjengelighet. Her bruker man fysisk modularitet, der luftgap deler opp ... -
Design of a Power-Dense Aviation Motor With a Low-Loss Superconducting Slotted Armature
Mellerud, Runar; Hartmann, Christian Magnus; Klop, Casper Leonard; Austad, Sindre; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2023)This article describes the design and analysis of a 2.5-MW, 5000-rpm electric motor with a slotted armature employing REBCO high-temperature superconductors (HTS). The alternating current and field in the armature induces ... -
Dual Use of Liquid Hydrogen in a Next-Generation PEMFC-Powered Regional Aircraft with Superconducting Propulsion
Hartmann, Christian Magnus; Nøland, Jonas Kristiansen; Nilssen, Robert; Mellerud, Runar (Peer reviewed; Journal article, 2022)In this paper, we present a comprehensive model framework for a disruptive cryo-electric propulsion system intended for a hydrogen-powered regional aircraft. The main innovation lies in the systematic treatment of all the ... -
Electro-Thermal Homogenization of HTS Stacks and Roebel Cables for Machine Applications
Klop, Casper Leonard; Mellerud, Runar; Hartmann, Christian; Nøland, Jonas Kristiansen (Journal article; Peer reviewed, 2024)This paper presents a homogenized electro-thermal model for high-temperature superconductor (HTS) stacks made of multiple REBCO tapes, which reduces the computational complexity of their thermal analysis. The electromagnetic ... -
Next-Generation Cryo-Electric Hydrogen-Powered Aviation: A Disruptive Superconducting Propulsion System Cooled by Onboard Cryogenic Fuels
Nøland, Jonas Kristiansen; Mellerud, Runar; Hartmann, Christian Magnus (Journal article; Peer reviewed, 2022)The idea of hydrogen (H2)- powered airplanes has recently attracted a revitalized push in the aviation sector to combat carbon dioxide (CO2) emissions. However, to also reduce, or even eliminate, non-CO2 emissions and con- ... -
Production and development of HTS terminations for future HTS coil manufacturing
Aabrekk, Erling Andreas (Master thesis, 2023)Avslutningsmetodar/festepunkt for enkle og parallellkopla REBCO HTS teipar har blitt undersøkt i laboratorieeksperiment for å oppnå handteringskunnskap for framtidige eksperiment og produksjon av HTS spolar for EME ...
