摘　　要：混合励磁转子在生产过程中有较高的工艺要求,针对在制造过程中磁钢极性正确安装,流程检验中励磁线圈与集电环电励磁极性的判别,以及不同磁钢材料运用对性能提升的效果这3点作为切入点,通过磁钢与爪极的阵列配合,设计专用的检验设备在检验环节对励磁线圈进行通电校验,并使用不同材料磁钢进行发电机的性能试验。结果表明,配合励磁线圈正负极与磁钢组成海尔贝克阵列,能有效提升发电机输出功率,且汝铁硼材料相较于铁氧体对电性能的提升有更好的效果。The hybrid excitation rotor has higher process requirements in the production process.This paper discussed hybrid excitation rotor from 3 perspectives,i.e.how to correctly install the magnetic steel polarity in the manufacturing process,the identification of the magnetic polarity of the excitation coil and slip ring in the process inspection and the effect of different magnetic steel materials on the performance improvement.Through the combination of magnetic steel and claw pole arrays,a dedicated inspection equipment was designed to verify the excitation coil during the inspection process,different materials of magnetic steel were used for performance testing of the generator.The results show that combining the positive and negative poles of the excitation coil with the magnetic steel to form a Haier Beck array can effectively improve the output power of the generator,aluminum iron boron material has a better effect on improving electrical performance compared to ferrite.
