Abstract

The optimization of the permanent magnet shape and dimension is crucial for the performance improvement of axial flux permanent magnet (AFPM) machines. In this paper, different magnet shapes are studied and compared based on the performance results. A new magnet shape is also proposed. The cogging torque is considered the most prominent noise source in axial flux permanent magnet (AFPM) machines. Different magnet shapes are analyzed and compared to optimize the efficiency of axial flux permanent magnet (AFPM) machines. Flat trapezoidal pole, curved pole and skewed pole are studied and analyzed and a new shape which is a combination of curved and skewed magnet shape is proposed to further reduce the cogging torque and improve the overall efficiency of axial flux permanent magnet (AFPM) machines. The study focuses on single-sided machines, but the results are valid even for double-sided machines and can be easily extended to other configurations.

轴向磁通永磁电机转子不同拓扑结构的比较研究

永磁体形状和尺寸的优化是提高轴向磁通永磁(AFPM)电机性能的关键。本文根据性能结果对不同形状的磁体进行了研究和比较。提出了一种新的磁体形状。齿槽转矩是轴向磁通永磁(AFPM)电机中最主要的噪声源。为了优化轴向磁通永磁(AFPM)电机的效率，对不同形状的磁体进行了分析和比较。对平面梯形磁极、弯曲磁极和倾斜磁极进行了研究和分析，提出了弯曲磁极和倾斜磁极相结合的新型磁体形状，以进一步减小轴向磁通永磁(AFPM)电机的齿槽转矩，提高整机效率。研究的重点是单面机器，但结果是有效的，即使是双面机器，可以很容易地扩展到其他配置。
