摘　　要：研究了一种新型轴向磁通电励磁双凸极电机。在轴向磁通永磁电机的基础上,用励磁绕组取代原电机的永磁体,发电运行时,无需功率变换器和转子位置传感器。兼具了轴向磁通与电励磁双凸极电机的优点,电机结构简单、新颖,励磁磁场可调,功率密度高。采用双定子结构,励磁效率高。转子铁心凸极数为3个,有利于降低铁损。采用三维电磁场有限元法对电机的静态特性参数进行仿真分析,并初步验证该电机的合理性。A new type of axial flux electro-magnetic generator with doubly salient structure was proposed. The permanent magnet of the axial flux DSPM was replaced by the electric field coils. There was no need for the power converter and rotor position sensor when the motor was operated. It combined the advantages of axial flux and doubly salient excited motor.The configuration of the motor was simple and novel,the excitation field was adjusted and its power density was high. The excitation efficiency was high due to the double stator structure. The number of salient poles of the rotor was 3,which helped to reduce the iron loss. The three-dimensional finite element method was used to simulate and analyze the static characteristic parameters of the motor,the results of the simulation can initially verify the effectiveness of the proposed motor.
