| 摘 要： | 永磁同步电机（PMSMs）具有高效、高转矩密度、高功率因数等优点，应用于发电厂辅机系统节能效果显著，具有很好的应用前景好。搅拌机是辅机系统的重要部件，本文基于Easimotor软件的磁路法，为搅拌机设计了一字形、V形、U形与W形转子结构的四种嵌入式PMSMs。在保持定子不变的条件下，比较了四种PMSMs的效率、功率因数与永磁体用量，表明U形转子性能更具有优势，而且永磁体用量少。基于有限元建立了其2D仿真模型，仿真分析空载时的磁场分布与齿槽转矩、额定负载时的磁场分布、平均电磁转矩与转矩脉动，为搅拌机高效永磁同步电机的设计提供参考。

| Abstract: | The permanent magnet synchronous motor (PMSMs) have the advantages of high efficiency, high torque density, high power factor and so on. When they are applied in auxiliary electrical system of power plant, the energy saving effect is remarkable and the prospect of application is fine. The blender machine is one of important part. For this blender machine, four PMSMs with I-shaped, V-shaped, U-shaped or W-shaped rotor topologies are designed based on the magnetic circuit method of Easimotor software. Under same stator condition, the performance of efficiency and power factor and the volume of PMs are compared. The U-shaped rotor topology is shown the be st performance with lowest PM volume. By its 2D simulation model erected in FEM software, the performances including no-load back-EMF, cogging torque and the rate-load magnetic field distribution, average electromagnetic torque and torque ripple are calculated. The research can supply the support to the high efficiency PMSM design applied in blender machine. |
