Abstract
In the development of more-electric aircraft, the motors with high torque density and specific power are required within the weight restriction. In this article, a novel hybrid axial transverse flux permanent magnet motor (HATF-PMM) is proposed with compound permanent magnet (PM) rotor, which exhibits great torque capacity to satisfy the requirement in more-electric aircraft. The method of electromagnetic characteristic superposition is highlighted in this article for the first time to decouple the magnetic field and reduce dimensionality. Considering the calculating time and accuracy, an analytical model (AM) based on the subdomain method is utilized to calculate the magnetic field of the proposed HATF-PMM and further obtain the electromagnetic characteristics, which is verified by finite-element analysis (FEA). Then, the HATF-PMM is optimized with the objective of high specific power by using the AM. In the end, the analysis results and performance of the proposed HATF-PMM are validated by the prototype experiment, which proves that the HATF-PMM has great potential in the application of more-electric aircraft.
