| Summary: | As electric vehicles (EVs) become increasingly popular, there is a crucial demand for efficient and reliable motor systems. This project focuses on designing a dual three-phase permanent magnet synchronous motor (DTP-PMSM) with a 48-slot/22-pole configuration and a 30° phase shift angle, specifically tailored to achieve high efficiency and high power density for EV application.
The innovative DTP winding configuration enhances reliability and significantly reduces harmonics in the armature's magnetic field, addressing critical challenges in conventional single three-phase PMSMs, such as cogging torque and harmonic distortion. Finite-element method (FEM) analysis, conducted using JMAG software, facilitates detailed simulations of the motor's performance, including magnetic field distribution, torque characteristics, energy losses, and thermal behaviour under various operating conditions.
This report outlines the design process, analyses the technical challenges encountered, and discusses the solutions implemented. The results indicate that the DTP-PMSM has the potential to meet the evolving standards in EV propulsion systems. Finally, the report concludes with insights into the findings and recommendations for future advancements in high-efficiency motor designs aimed at sustainable transportation. |
