摘　　要：针对卫星姿态控制用反作用飞轮小型化的要求,设计了采用印刷电路板(PCB)定子绕组形式的轴向磁通反作用飞轮系统,并研究了PCB定子绕组的布线形式。根据系统设计方案和工艺的要求,采用理论分析与有限元仿真相结合的方法,研究了螺旋形绕组的反向转矩产生机理,对比分析了螺旋形和波形PCB定子绕组对飞轮驱动电机性能的影响,并分别对采用两种形式定子绕组的飞轮样机进行了地面性能测试。试验结果表明,飞轮工作在额定转速5 000r/min时,采用波形定子绕组比采用螺旋形定子绕组时的电机功耗降低了26.2%,电磁效率降低了0.8%。试验结果验证了理论分析与仿真结果的正确性,为PCB定子绕组型轴向磁通永磁电机的工程化应用提供了参考。To meet the miniaturization requirements of a reaction flywheel for small satellites,a reaction flywheel system using the axial flux permanent magnet motor based on a Printed Circuit Board（PCB）stator was proposed and the winding layout form for the PCB stator winding was researched as well.According to the system design and manufacturing requirements,a combination of theoretical and finite element analysis was applied to the illustration of generating mechanism of the reverse torque in the spiral winding.The effects of spirally type and waveform type PCD stator windings on the flywheel system performance were also analyzed,respectively.Finally,the performance of flywheel system prototypes with two forms of stator windings was tested on the ground.The results indicate that the driven motor with the waveform PCB stator winding has reduced its power consumption by 26.2%than that with spirally winding when the flywheel works at a ratedspeed of 5 000r/min,meanwhile its electromagnetic efficiency is also reduced by 0.8%.The experimental results verify the correctness of theoretical analysis and simulation results,and provides an important reference for the engineering applications of the axial flux permanent motors with PCB stator windings.
