摘要
介绍了一种直线永磁往复式发电机的结构及其工作原理,并采用有限元法对永磁体不同位置的磁场进行了分析,阐述了磁场的分布状况,计算得到空载电动势和负载电磁力,并把计算结果与测试值做了误差分析。通过分析可知,计算结果和测试值基本一致。
This paper introduces the construction and principle of a kind of linear permanent-magnet reciprocating generators. The magnetic field of the permanent magnet at different position is analyzed by finite element method and the distribution of the magnetic field is stated. The electromotive force at no load and electro-magnetic force at load are calculated and the error between the calculated results and the measured values is analyzed. The result indicates that the calculated and the measured values are basically consistent.
