| 摘 要： | 双余度无刷直流电动机由于具有较高的安全性和容错性,已广泛应用于电力作动器等关键电力系统中.由于器件以及电机制造上的各种因素,两个电气余度的参数不会完全一致,电流出现不均衡的情况,将导致电机铜损的剧增、散热条件的恶化以及输出转矩的较大波动,影响到双余度电机性能的发挥.通过对双余度无刷直流电动机铜损以及转矩波动的分析,得出了电流不均衡情况下电机铜损变化规律和转矩波动规律,并通过样机验证了理论分析结论.

| Abstract: | Dual redundancy brushless DC motor has been widely used in the electric actuators and other crucial power systems for its safety and fault tolerance.Because of the device and the motor manufacturing,many electrical parameters are not exactly the same,which make the current situation unbalanced and cause the rapid increase of copper loss,heat dissipation problem and the torque ripple.The change rules of copper loss and torque ripple rules were obtained through the analysis of dual redundancy brushless DC mot... |
