AI Technical Summary
Technical Problem
[0003]相关技术中，行业内风扇电机多采用定子铁芯套绝缘框架内绕的形式，来实现绕组与外部原件电连接，这种结构的电机定子在绕线时，需刻意避让外圆边凸起结构，操作难度增加，且易发生漆包线挂绕在边缘的卡线问题，影响生产效率，而且漆包线在卡线后还易裸露在框架外，在后续装配或运输中易受机械应力，存在断线隐患
Benefits of technology
[0014]综上所述，由于采用了上述技术方案，本实用新型的有益效果是：通过对传统电机定子上的绝缘框架改善，取消了传统绝缘框架的外圆边，这种结构在定子绕线时可提高绕线的效率，同时还能减少漆包线挂在外圆边的不良隐患，电机定子绕完线后，在绝缘框架外围套一层外保护件，可以改善现有技术存在的问题，使整个定子的绕组有更好的防护，能够降低了漆包线因外露而断线的情况，在提高电气连接的稳定性和可靠性的同时，还能提高定子的绕线效率，具有目前产品所不具备的优点，值得推广。
