Description

涵道式双磁路无铁芯潮汐发电机 技术领域
本发明涉及发电技术领域。具体地讲,是在水下利用潮汐水流发电的涵道式双磁路无铁芯潮汐发电机。
背景技术
常规永磁发电机主要由一个定子铁芯绕组结构和一个永磁转子结构组成,由于定子绕组依次设置于硅钢片铁芯的齿槽中,定子绕组的铁芯结构与永磁转子的气隙之间,自然会产生一种永磁铁吸合硅钢片铁芯的齿槽阻力矩。永磁发电机在发电时,这种被吸合的定子齿槽结构又会产生磁滞阻力和涡流阻力现象,并且产生铁损的热能消耗。所以能量转换效率更高的无铁芯发电机将成为电机行业的发展方向,但是,由于无铁芯定子绕组没有硅钢片铁芯的导磁作用,相对于无铁芯定子绕组切割旋转磁场磁力线的密度就会减少,如果解决上述问题必须增加永磁转子结构的磁通密度,势必增加发电机永磁铁的采购及生产成本。
