摘　　要：研究了一种结构较为新颖的航空永磁同步电机-双机共轴余度系统,双余度电机系统由两台共轴的永磁同步电动机和两套独立的功率变换器组成。通过两台电机在不同运行模式下的协调工作,使余度系统在故障时能实现容错运行,有效地提高机载电气系统的安全性和可靠性。仿真分析及实验结果均表明共轴余度电机系统具有良好的稳态和动态特性。A dual-redundancy aviation AC motor system is constructed by two permanent magnet synchronous motors fitted on the same shaft and two independent power drive circuits. Under two fault-tolerant conditions, the redundancy motor system can continue to operate in a satisfactory manner after sustaining a fault so that the security and the reliability of electric installations on aircrafts be significantly improved. Simulation and experiment results showed that the dual-redundancy motor system could realize high performance.
