| Title | Design Optimization of Outer-Rotor Permanent Magnet Synchronous Motor for Automated Ground Vehicles |
| Summary | Permanent magnet synchronous motors (PMSMs) with outer rotor configurations are increasingly adopted in automated ground vehicles (AGVs) for their compact structure and high torque density. However, the motor’s electromagnetic performance, including torque ripple and efficiency, is significantly influenced by slot/pole combinations and permanent magnet (PM) shapes. This project focuses on optimizing slot/pole ratios and PM geometries to enhance torque quality and operational stability, tailored for AGV applications. The research includes the following tasks: (1) Analyze the impact of slot/pole combinations (e.g., 12-slot/10-pole vs. 12-slot/8-pole) on cogging torque, back-EMF harmonics, and torque ripple. (2) Optimize permanent magnet shapes (e.g., arc-shaped, segmented) to suppress air-gap flux density harmonics and improve torque quality. (3) Develop parametric JMAG models for outer rotor PMSMs with varied slot/pole combinations and PM geometries to iteratively reduce torque ripple. (4) Validate optimized designs by comparing torque ripple reduction, efficiency gains, and thermal stability under AGV operational loads. |
