This thesis presents the design and analysis of the performance of a novel flux-intensifying permanent magnet synchronous motor (FI-PMSM), which is derived from a conventional spoke-type PMSM motor. Rare earth materials are gradually becoming scarce and expensive, making it necessary to reduce their use in PMSM motors. However, reducing the amount of permanent magnet used can cause demagnetization during motor operation, leading to decreased overall performance. To address this, the FI-PMSM machine has gained popularity worldwide. In this work, a spoke-type FI-PMSM motor is proposed to improve the risk of irreversible demagnetization, enhance output torque, reduce torque ripple, and extend the continuous power-speed ratio (CPSR) region.
The rotor design process for transforming a flux-weakening spoke-type PMSM motor into a flux-intensifying one is also presented in this thesis. The effects of rotor flux barriers on output torque, torque ripple, demagnetization, and CPSR region for the proposed model are also studied. The results indicate that the proposed FI-PMSM model produces higher output torque, lower torque ripple, reduced risk of demagnetization, and a wider CPSR region compared to the conventional spoke-type model. Ultimately, the main goal of this work is to design a new motor for electric vehicles, and the findings suggest that this type of motor is a promising candidate for such applications. Finally, a prototype motor is manufactured for validation.
