摘要
为了直接把海洋的波浪能转换为电能,提出了一种永磁直线波力发电机。设计了电机的结构。以一个定子模块数为3,振子永磁体磁极数为5的直线发电机为例,采用电磁场有限元方法分析了电机磁场和空载感应电动势,求解发电机定子绕组的电感参数,计算了发电机的功角特性曲面。对感应电动势的实验结果与计算结果进行比较,相对误差为6.8%。该型永磁直线波力发电机在振子速度为0.9m/s时最大输出功率可达80W,能够有效利用海洋波浪能发电。
A permanent magnetic （PM） linear wave power generator was developed to generate electricity directly from wave power. The stator has 3 modules, while the vibrator has 5 PM poles. The field and the induced electromotive force under no load conditions was analyzed using the finite element method （FEM）. The stator inductance was analyzed to give the power angle curve. The relative error between the calculated values for the induced electromotive force and the measured values is 6.8%. The peak output power is about 80 W with a vibrator speed v = 0. 9 m/s.
