摘要
阐述了轴向磁场盘式永磁无刷直流发电机的结构及其特点,提出了气隙磁场的简化模型,并对三维磁场进行了分析,在此基础上探讨了这种电机的设计方法,以最大功率输出为优化目标,导出了几个简单实用的设计公式。6极9相样机的实测数据证实了分析和设计方法的正确性,这种无刷直流发电机结构紧凑,效率高,特别适用于由引擎驱动的发电系统。
A novel type of axial-fiem disk-type permanent magnet brushless DC generators with u-nique arrangement and salient features is presented.Based on a simplified model for the mag-netic field in the airgap region of the machines,which is validated by a 3-D finite elementanalysis,the design of the slotless permanent magnet generators is investigated.Some sim-plified analytical expressions are derived and usedto optimize the design for several key pa-rameters on machine using Nd-Fe-B magnets.The test results of a prototype machine wellprove the design method.It is shown that the generating system with such a machine is par-ticularly suitable for the mobile engine-driven DC power supply.
