提出了一种新型轮辐式容错永磁无刷电机的非线性自适应集中参数磁路模型。LPMC方法可以作为有限元辅助设计工具,大大减少了总的计算时间。因此,用它来计算ST-FTPM电机的磁链、反电动势、电感和转矩性能。本文的创新之处在于基于改进的LPMC模型对短路电流进行预测。同时,为了保证分析精度,在模型设计中考虑了磁饱和的影响。有限元分析和实验结果验证了该模型的有效性。
This paper proposes a nonlinear adaptive lumped parameter magnetic circuit (LPMC) model for a new spoke-type fault-tolerant permanent-magnet (ST-FTPM) brushless motor. The LPMC method, which reduces the total computational time greatly, can be used as a finite-element method (FEM) assistant design tool. Hence, it is used to calculate the flux linkage, back-electromotive force (back-EMF), inductance, and torque performance of the ST-FTPM motor. The novelty of this paper is to predict short-circuit current based on the developed LPMC model. Meanwhile, in order to ensure the analytical accuracy, the magnetic saturation is considered in the model design. The effectiveness of the presented LPMC model is verified by FEM and the experiments.
