Control of a Multiphase Superconducting Axial Machine Drive for Electric Aircraft
摘要
In recent years, increasingly restrictive emissions regulations have driven the demand for sustainable aviation, leading to the development of electric propulsion systems – particularly high-power-density electrical machines – as one of the promising alternative solutions to traditional gas turbine engines, particularly high-power-density electrical machines. Applying High-Temperature Superconductors (HTS) to electrical machines is considered promising due to their high current density and negligible energy losses, enabling the creation of compact and power-dens machines that are viable for aviation applications. This work presents a preliminary study for the drive control of a multiphase axial-flux superconducting machine with an HTS disc rotor made of rare-earth barium copper oxide (REBCO) tapes, providing a presentation of the control architecture and simulation of the inverter. The double-stator is made of conventional windings, generating magnetic poles that can be changed electronically. Furthermore, multiphase machines are more fault-tolerant compared to traditional three-phase machines, making them more reliable for electric aviation.
