摘要：波浪能是一种新型的清洁能源,近几年提出了多种对波浪能进行开发的方案,但大多都是在波浪能和发电机之间加入转化装置,这样效率低,成本较高。该文提出了永磁圆筒型直线发电机可以将波浪能直接转化为电能。详细阐述了该发电机的结构,并且基于电磁场有限元分析软件Ansoft对于发电机进行仿真,得到空载电压的波形。通过改变永磁体长度对发电机进行优化设计,最后给出优化后发电机的三相空载电压波形和负载特性。仿真结果可以指导磁体结构的圆筒型直线发电机的理论研究。

摘要：A dynamical dq model is proposed for a linear flux-switching permanent magnet（LFSPM） machine which is suitable for high-precision control *** operation principle of the prototype machine is analyzed using the finite element method（FEM）,and the parameters,such as the back electromotive force（EMF） and the phase flux linkage,are *** calculated and measured results reveal that the back EMF and the flux linkage are essentially sinusoidal,and the variation of the phase flux linkage profile of the LFSPM machine is similar to that of the linear surface permanent magnet（LSPM） *** on this,a dynamical dq model and a simulation control model are *** simulation results are compared with the test results obtained from a DSP-based control platform,which verifies that the model is correct and ***,the model can be used for design optimization and control development.
