The invention discloses a cylindrical double layer winding linear permanent magnet synchronous generator. Including the outer cylinder is provided with a plurality of annular permanent magnet and the first group are separated from each other across the magnetic shaft and the inner and outer core hole around the circular permanent magnet multiple outer winding and the same number of second groups are separated from each other across the magnetic ring. In the center of the shaft is provided with a center hole, is arranged in the center hole, the inner cylinder is arranged on the outer winding third groups across the magnetic separation, the bottom surface of the inner core spring mounting shaft is provided with a center hole and inner side of the inner core and outer core, face mounting end cover; an annular air gap between the outer winding with the same height respectively. And the permanent magnet and the inner winding. The invention adopts the double stator structure with no alveolus and movable magnetism. The utility model has the advantages of quick response and high utilization ratio of the magnetic field when the positioning force is eliminated. No intermediate conversion device is used to convert linear motion into electric energy output, which can be used in occasions such as piston and wave power generation, and energy saving and environmental protection.

技术介绍
随着人们对能源和环境的关注,可直接利用物体的机械振动发电的直线发电机逐 渐成为国内外研究的热点。与传统的旋转发电机不同,直线发电机可以将生产、生活中的直 线运动直接转化为电能,不仅减少了能量的损失,而且扩大了应用范围。振动无处不在,活 塞的运动、车辆的抖动,在海洋的潮汐和波浪能量的利用中,直线发电机可以直接通过次级 的上下运动产生交变电流,简单高效的直接性能量转化方式促进了直线发电机的发展和应 用。目前国内一般采用传统圆筒形直线发电机多采用动磁式结构,初级由铁心和绕组 组成,管型铁心内侧均勻开有环槽,铁心槽内嵌套有电枢绕组;次级由铁心和永磁体组成, 圆环形永磁体采用径向或者轴向充磁方式,固定在次级铁心外侧,通过轴承与外部驱动设 备相连。这使得直线发电机在运行时存在有一下几个主要问题1、电机的齿槽效应会产生定位力,影响了电机运行的稳定性;2、铁心的存在增加了次级的重量,降低了电机的响应速度;3、铁耗较高,限制了电机效率和永磁体利用率的提高。
