摘　　要：针对直驱漂浮点吸收式波浪能装置,提出一种直线电机设计方案。分析了电机模型,并采用电磁场有限元方法分析了电机性能,给出了电机空载状态下感应电动势波形及负载状态下输出电压波形。通过改变电机定子铁心长度对电机进行了优化设计,最后给出了电机所受磁阻力大小。该型电机在动子速度为1m/s时,输出功率可达10kW,能够有效利用波浪能发电。A linear generator＇s design proposal was developed for the direct driven floating point absorption wave energy device. The model of generator was analyzed, and the performance of generator was analyzed by using electromagnetic field finite element method, the waveform of induction under no load condition and the waveform of output voltage under load condition was obtained. Optimized design of the generator was obtained by changing wave energy the length of stator, finally, detent force of generator was offered. The generator can transform to electric power effectively when output power is about 10 kW with a rotor speed 1 m/s.
