摘要：

Five-phase fault-tolerant doubly salient electromagnetic generator (FTDSEG) is proposed for high reliability applications in this paper. On the basis of comparative analysis on structure characteristics between five-phase non-fault-tolerant doubly salient electro-magnetic generator (NFTDSEG) and five-phase FTDSEG, the variation of stator and rotor pole number from NFTDSEG to FTDSEG is revealed and the phase width of back electromotive force (EMF) of five-phase FTDSEG approaching 144 is deduced. Then the flux linkage and EMF of five-phase NFTDSEG and five-phase FTDSEG are investigated using finite-element method with two dimensions and four fault modes of five-phase FTDSEG are analyzed in detail. The laws of fault operating influence on external and power characteristic of motor and output voltages of rectifier are researched in four fault modes with different exciting currents. Meanwhile, the reason why the output voltage of rectifier of single phase short circuit fault is bigger than open circuit fault is given. Finally, the fault-tolerant characteristic of five-phase FTDSEG is verified by the experimental results.
