This dissertation presents the design and performance analysis of five-phase ferrite permanent magnet assisted synchronous reluctance motor (Fe-PMaSynRM). The risk of irreversible demagnetization and mechanical deformation are two major challenges in the five-phase Fe-PMaSynRMs. To address these critical issues, this dissertation presents the design considerations for the internal rotor and the external rotor Fe-PMaSynRM. To improve anti-demagnetization ability of the internal rotor Fe-PMaSynRM, a unique rotor structure is proposed with augmented sets of design variables. In addition, to reduce its mechanical stress, novel weight-reducing notches are adopted. The external rotor Fe-PMaSynRM is designed to offer a higher torque density, while the anti-demagnetization ability has been maintained to be comparable to the internal rotor counterpart.The finite element analysis (FEA) model has been utilized to obtain the proposed designs and satisfy the performance specifications. An extensive multiphysics FEA analysis has been conducted on the proposed design to ensure its electromagnetic and structural integrity under critical operating conditions. Simulation results show that the anti-demagnetization abilities of the proposed designs are nearly doubled compared to the state-of-the-art Fe-PMaSynRM designs. To validate the theory and simulation results, the proposed designs of a 3kW internal rotor and a 3.7kW external rotor Fe-PMaSynRM have been fabricated and tested. The simulations and experimental results show acceptable matching with FEA results, which validates the proposed designs and analysis.
