中文摘要:
      对称六相永磁同步电动机(PMSM)和三相 PMSM串联系统中,电机空间谐波对解耦运行存在耦合问题,文章以短矩集中绕组的串联电机为研究对象,利用绕组函数分析了各台串联电机包含的各次谐波的耦合影响规律,构建了对称六相 PMSM中含有 2、4次空间谐波时的串联系统数学模型,推导了电磁转矩的耦合表达式,通过变速运行的仿真,分别进行了耦合运行及其解耦运行的验证。
英文摘要:
      Space harmonics has effects on decouple operating of symmetrical six-phase PMSM and three-phase PMSMSeries-connected system. The couple effects laws by each order harmonic for the series-connected system with short pitchconcentrated windings were analyzed. The mathematic models with 2th and 4th harmonics of symmetrical six-phase PMSMunder d-q coordinates were deduced. The couple expressions of torque was deduced. And the simulations with variablespeed operating were proposed to validate the feasibility of couple and decouple operating.
