Description

超高转速风类电机 技术领域
本发明涉及电机技术领域，特别涉及一种超高转速风类电机。
背景技术
目前，电吹风、无叶电风扇、负压吸尘器、干手器、卫浴干燥等所使用的电机，一般采用单悬臂结构，采用单悬臂结构容易造成偏心，在高速电机启动的时候，单悬梁臂的转子受到磁场力的作用，受到很多的径向力，此外，单悬臂梁结构，即使增加了固定定子措施，仍然不能完全保证电机转子启动时摇摆，由此造成电机启动时产生很大的声音；为了减少单悬臂梁结构摇晃，固定电机转子两个轴承距离比较大，加上转子的长度，电机总体高度比较高，造成安装不方便。
为了减少电机的轴向长度，通常采用胶水固定，通过胶水固定时，因为胶水不能反拆，一旦出现问题，则造成报废材料，如果由于员工操作不当，则容易造成胶水不牢靠，轻者造成变音，噪音加大，严重者造成电机失效。
另外，目前的电机中间一般安装有轴承挡板，增加了轴向长度，导致安装空间受限。
