如图5所示，磁铁组件4包括安装架和多个磁铁43，安装架包括依次套设的外安装环41、内安装环42和轴支架44，位于绕线架2内部的所述磁铁组件4中，外安装环41的外径小于外环架21的内径，以保证该组磁铁组件4在绕线架2内的转动不受影响，外安装环41与内安装环42之间用于固定磁铁43，轴支架44固定在内安装环42内，且轴支架44用于固定套设于动力元件5的转轴52上，并在动力元件5的带动下转动，磁铁43围绕内安装环42均匀周向固定，实现磁铁43的固定，以及保证磁铁43和线圈3的相互作用，优选地，磁铁43为永磁合金。
轴支架44为三角轴支架，且轴支架44上设有散热孔，整体美观坚固，且散热孔的设计能够利于空气的流通，以便于后序散热使用。但本发明提供的无刷永磁发电机100中对于轴支架44的具体形状并不限定于三角轴支架，本领域技术人员可根据实际需要对其形状作适应性更改，只要能够满足支撑效果以及能够保证空气流通即可。
各磁铁组件4中的磁铁43为六个，且相邻的磁铁43之间有间距，各磁铁43的形状与相邻的连杆组23之间的间距形状一致，相邻磁铁43的磁极朝向相反，各磁铁43的异端相邻，能够最大限度地减少磁漏和磁衰；磁铁43共有十八块，线圈3和磁铁组成永磁阵列，但本发明提供的无刷永磁发电机100中，各组磁铁组件4中磁铁43的数量不限于六个，只要保证是双数个即可，且各磁铁组件4上的各磁铁43的位置相对应，以保证正常发电。当动力元件5带动磁铁组件4转动时，同一纵截面上的六块磁铁43(即八个磁极作用)的组合方式正好会让该线圈3形成一个同向电流；随着动力元件5的转动，各磁铁组件4也随之转动，由于相邻的磁铁43磁极相反，因此当另一组磁铁43磁极经过该线圈3时又会产生反向电流，进而形成交流电，更优的，还可使各线圈3并、串联以实现多项宽幅电压输出。
动力元件5包括转轴52和动力轮51，动力轮51位于机壳1外部，并用于与外部驱动装置固定，进而在外部驱动装置的带动下转动，转轴52的一端转动安装在机壳1的内壁上，转轴52的另一端穿过机壳1的侧壁并与动力轮51同轴固定，保证转轴52转动的稳定性，优选地，转轴52与机壳1之间通过轴承连接。
转轴52上固定有散热元件7，散热元件7位于机壳1内部，且靠近动力轮51设置，机壳1上对应散热元件7的位置开设有散热孔，散热元件7用于将机壳1内的热量经散热孔导出至外界，避免由于温度过高影响正常工作，优选地，散热元件7为散热扇。
机壳1的下端还固定有底座6，底座6用于支撑机壳1和接地使用，保证工作安全性。
本说明书中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时， 对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上，本说明书内容不应理解为对本发明的限制。
