Design and Assembly of a 250 kW Partially Superconducting Flux Modulation Machine

This article presents the superconducting machine demonstrator realized within the frame of project FROST (Flux-barrier Rotating Superconducting Topology) which started in 2020. This demonstrator is a 250 kW partially superconducting machine adopting the so-called flux modulation topology which employs a superconducting static coil fed with DC current to produce a magnetic field which is modulated by a rotor composed of superconducting bulks. Both these components are the machine inductor which generate a torque by interacting with a three-phase conventional copper wound armature. This article presents the machine expected performances as well as an overview of the demonstrator assembly.
