Abstract：Based on the original combination of the permanent magnet synchronous machine and the doubly salient electro-magnet machine, this paper presents a new topology of parallel hybrid excitation brushless dc machine (PHE-BLDCM). Matching rules of slot/pole number are determined and the configurations of the armature windings are discussed, including the one possessing the fault-tolerant ability. 2D-finite element analysis(2D-FEA) is used to analyze performance characteristics of two machines, and the whole PHE-BLDCM is analyzed by 3D-finite element analysis transient field. The results of the study confirm: the PHE-BLDCM achieves efficient operation of two kinds of different principle brushless machine; for its structure is simple and reliable, air-gap field is easy to bidirectional adjustment and de-excitation at fault is achieved when the short-circuit of the internal windings happens in the part of permanent magnet synchronous machine, the PHE-BLDCM has important application value in the occasion of the aircraft power for starter-generator.
