| 摘 要： | 为了提高功率密度和转矩密度,需要在六相感应电动机中注入三次谐波电流,这势必导致控制系统的复杂化。为了分析定子绕组流过非正弦电流时,六相感应电动机的运行性能,必须了解谐波电流与谐波磁势的关系。运用了傅里叶分析和绕组函数的方法,推导了六相感应电动机的磁动势,同时给出了考虑三次谐波电流时的数学模型,通过比较在绕组中注入和不注入三次谐波电流的仿真波形,得到了六相感应电动机加入三次谐波电流能够提高转矩密度的结论,所建立的仿真驱动系统,具有较高的有效性和可行性,且便于快速修改控制结构和相关参数。

| Abstract: | The mode of the triple-frequency harmonic wave injection to six-phase moter can improve power intensity and torque intensity,which will comlicate the drive system.In order to analyse the performance of the six-phase induction motorwith non-sinusoidal currents in stator windings, the relationship between the harmonic currents and the corresponding harmonic magnetic mofive force(MMF) should be understood. This paper presents MMF of a six-phase induction motor by means of fourier analysis and winding function ... |
