摘要:
无刷双馈电机( BDFM) 结构特殊,磁场调制机理复杂,目前尚缺少有效工具可快速而准确地对其运行特性进行分析。为此,根据磁网络的基本概念,结合笼型转子BDFM 的结构特点并考虑铁心饱和与转子旋转的影响,阐述了笼型转子BDFM 等效磁网络的建模方法; 在此基础上,建立了一个笼型转子BDFM 样机的动态磁网络模型,利用回路法对其进行求解,进而得到并分析了BDFM在多种不同工况下的运行特性; 最后,将动态磁网络模型的分析结果与有限元分析结果和样机实验数据进行了对比。结果表明,笼型转子BDFM 动态磁网络模型在保证准确性的前提下,计算速度与有限元法相比明显提升,为分析笼型转子BDFM 的运行特性提供了新思路。
Abstract:
 There are few effective tools to quickly and correctly analyze the operating performances of Brushless Doubly-Fed Machine ( BDFM) due to its special structure and complex magnetic field modulation mechanism. Based on the basic concept of Magnetic Equivalent Circuit ( MEC) ,the method for establishing the MEC model of BDFM with cage rotor was proposed,considering the effects of special structure of BDFM,core saturation and rotor revolution. Furthermore,a dynamic MEC model of a prototype with cage rotor was built up and solved by the mesh method. And then,the operating performances of the prototype under different operating conditions were obtained and analyzed. Finally,the results of dynamic MEC model were compared with those of Finite Element Analysis ( FEA) and experiment data. The results show that the dynamic MEC model can correctly predict the operating performances of BDFM with cage rotor and is much faster than FEA. This work brodens the research thought for analyzing the operating performances of BDFM of cage rotor.
