摘　　要：为了使新型直线波力发电机能够良好运行,需要准确分析定位力的大小。以电磁场数值计算为基础,根据磁场能量的变化来求解电机的定位力。以一个定子模块数为3,振子永磁体磁极数为5的直线波力发电机为例,以单个振子永磁体块所受定位力为基础,确定电机的振子极距,并以此为基础求解出考虑导磁端盖影响的整个发电机振子所受定位力的变化。实验结果表明,与理论计算结果基本一致;所采用的定位力的分析方法是可行的和有效的,对进一步改进和优化直线波力发电机的设计具有重要参考价值。The analysis of cogging force is important in the novel wave power linear generator opera- tion. Based on numeric calculation of magnetic fields, the cogging force is calculated in terms of magnetic energy way. The stator has 3 modules, and the vibrator has 5 PM poles. The pole distance is determined by the cogging force of single magnetic pole. The cogging force of the vibrator is calculated. The calculated values agree well with measured values and the method could benefit the improvement and optimization of linear wave power generator design.
