Abstract

一种40-100VA永磁式无铁芯盘式外转子风力发电机，主要由定子轴(3)、外转子(2)、机壳(1)、耳座(4)及孔(5)组成。40-100VA永磁式无铁芯盘式外转子风力发电机是风光互补路灯系统工程中首选的电机。

Description

40-100VA永磁式无铁芯盘式外转子风力发电机
技术领域
离网型小型风力发电机
背景技术
小型风力发电机以内转子、有铁芯、水平轴运转居多，由于有铁芯，就有齿槽效应，产生定位力矩，微风难启动，由于水平轴运转，必须有转舵装置，结构复杂易损坏。
发明内容
本发明者的目的是解决消除离网型小型风力发电机的定位力矩，微风可以启动，垂直轴运转，去除转舵装置，不受风向限制。
实现上述目的技术方案是：一种40-100VA永磁式无铁芯盘式外转子风力发电机，主要由定子轴(3)、外转子(2)、机壳(1)、耳座(4)及孔(5)组成。其好处是：定位力矩小，微风可以启动，垂直轴运转，去除转舵装置，不受风向限制。
具体实施方案
如附图所示：一种40-100VA永磁式无铁芯盘式外转子风力发电机，主要由定子轴(3)、外转子(2)、机壳(1)、耳座(4)及孔(5)组成。
该电机轴向永磁励磁，多极数(20极以上)，磁路短，盘式内定子无铁芯，无齿无槽，所以没有齿槽效应，静态力矩极小微风即能启动，外转子结构，直接风力驱动，无增减速机构，传动效率高；风叶垂直安装，任何方向的风均可，不需要转舵装置；全封闭扁平式结构，防雨水，导热途径短，散热面积大，温升低，寿命长，双倍轴承支撑和加粗的轴伸，可抗御12级大风不损坏，电机外壳有伸出的耳座，安装风叶支架牢固又很方便，电机的顶端装有内风叶际杆，X形风叶沿导杆滑入至电机的顶端，上面用螺母锁定即可极其简单，且外形美观。
