Analysis of Reliability and FTA of Hybrid Excitation Synchronous Machine

Hybrid Excitation Synchronous Machine(HESM)is a kind of new machinery,which on the base of permanent magnetism simultaneous electrical machinery,adding the electricity excitation winding on the stator or the rotor of the electrical machinery to adjust the main magnetic flux of the electrical machinery.The article indicates that the work principle and the structure of HESM and establish the reliability pattern of HESM,using the reliability analysis method of FTA to take ration and the qualitative analysis on the reliability of HESM.
