In this article, a hybrid-slot radial-flux dual-stator permanent-magnet machine (HS-RDPM) with fault-tolerant consideration is presented. On the one hand, the torque density of this structure is improved compared with conventional fault-tolerant permanent-magnet machines (FTPMs). On the other hand, both large torque ripple and weak phase isolation coming from dual stators are optimized. First, radial-flux dual stators with higher torque density are extended to FTPMs innovatively. Second, to decrease torque ripple, dual-layer fractional-slot concentrated winding (DFCW) is used, while optimized rotor and staggered stators are proposed. Finally, the hybrid slots that are composed of deep and narrow notches (DNNs) and large-opening slots are raised to enhance phase isolation; meanwhile, the deflection teeth are proposed to increase slots’ utilization. The comparisons between HS-RDPM with conventional and intermediate structures are made. The higher torque density and smaller torque ripple are testified by back-EMFs and torques. The greater phase isolation is proven jointly by flux just with single-phase current, inductance performances, and back-EMFs varieties after a short circuit. In addition, the loss distributions are studied, while the winding temperatures indicate that the security of the machine under a short circuit can be guaranteed if the current is limited. A prototype is manufactured, and the experimental results verify the correctness of simulations.

考虑容错的混合槽径向磁通双定子永磁电机

在本文中,提出了一种具有容错功能的混合槽径向磁通双定子永磁电机(HS-RDPM)。一方面,与传统的容错永磁电机(FTPM)相比,这种结构的扭矩密度得到了改善。另一方面,来自双定子的大转矩脉动和弱相隔离都得到了优化。首先,具有更高转矩密度的径向磁通双定子被创新地扩展到FTPM。其次,为了减小转矩脉动,使用了双层分数槽集中绕组(DFCW),同时提出了优化的转子和交错定子。最后,提出了由深和窄槽口(DNN)和大开口槽组成的混合槽,以增强相位隔离。同时,提出了偏转齿来增加槽的利用率。进行了HS-RDPM与常规结构和中间结构的比较。反电动势和转矩证明了较高的转矩密度和较小的转矩波动。短路后,通量与单相电流,电感性能和反电动势变量共同证明了更大的相位隔离。此外,还研究了损耗分布,而绕组温度表明,如果电流受到限制,则可以保证短路情况下电机的安全性。制造了一个原型,实验结果验证了仿真的正确性。短路后,通量与单相电流,电感性能和反电动势变量共同证明了更大的相位隔离。此外,还研究了损耗分布,而绕组温度表明,如果电流受到限制,则可以保证短路情况下电机的安全性。制造了一个原型,实验结果验证了仿真的正确性。短路后,通量与单相电流,电感性能和反电动势变量共同证明了更大的相位隔离。此外,还研究了损耗分布,而绕组温度表明,如果电流受到限制,则可以保证短路情况下电机的安全性。制造了一个原型,实验结果验证了仿真的正确性。
