根据双凸极电机的机电能量转换过程，从磁能变换的角度分析了电励磁双凸极电机电动及发电时的工作原理。借助有限元仿真软件，针对同一台12/8极电励磁双凸极电机，分析了电枢反应对双凸极电机电动及发电功率的不同影响，比较了提前角度控制和不控全桥整流发电方式下电机的功率密度，给出了不同励磁电流下电机电动及发电功率特性曲线。对原理样机进行了试验，验证了仿真分析的准确性。分析结果表明：电励磁双凸极电机电动和发电最大功率点随励磁电流的增加不断增大，而相同转速、励磁电流条件下，双凸极电机电动功率大于发电功率。

According to the electro-mechanical energy conversion process of the Doubly Salient Motor( DSM) , operational principles of Wound-Field Doubly Salient Machine( WFDSM) , both applied as motor and generator, are illustrated from the perspective of magnetic energy transformation. By means of the finite element simulation software, the different influences on motoring and generating power due to armature reaction are studied in the same 12/8 pole WFDSM. Power density of motor is compared in advanced angle control mode ( AACM ) with that of generator in Doubly Salient Generating-2 ( DSG2 ) . The power characteristic curves are acquired under different excitation current. Beyond that, the experiments on prototype were conducted to validate the accuracy of the simulation. Results showed that: With increasing of the excitation current, the motoring and generating power of WFDSM continue to rise. However, the motoring power is greater than generating power under the identical velocity and excitation current.
