提出了一种基于高斯基函数的永磁电机2.5维多相拓扑优化方法。将转子中的设计区域分成圆柱层,对每一层进行二维拓扑优化,使平均转矩最大化,同时最大限度地抑制转矩脉动。所提出的拓扑优化可以确定转子铁心和磁体的形状,以及磁化方向。结果表明,与传统的2-D优化相比,优化后的2.5-D拓扑优化可以获得更好的转矩性能。
This article proposes a novel 2.5-D multi-phase topology optimization method using a Gaussian basis function for permanent magnet motors. The design region in the rotor was sliced into cylindrical layers; the 2-D topology optimization was performed for each layer such that the average torque was maximized, while the torque ripple was suppressed to the maximum possible extent. The proposed topology optimization could determine the rotor core and magnet shapes, as well as the magnetization direction. It was shown that the optimized 2.5-D topology optimization led to better torque performance when compared to conventional 2-D optimizations.
