Description

一种防着火阻燃塑封电机 技术领域：
本实用新型涉及一种防着火阻燃塑封电机。
背景技术：
现有的塑封电机的结构如图1、图2所示，包括转轴、转子组件、塑封定子组件、温控器和轴承支撑架10A，所述的塑封定子组件包括定子铁芯、定子绕组和注塑外壳20A，转轴安装在转子组件上，塑封定子组件中间设有中心孔，转子组件安装在中心孔里，中心孔的两端设有台阶，轴承支撑架安装在台阶上，轴承支撑架设置轴承室，轴承安装在轴承室里面，所述注塑外壳的端面和侧面上设有防火罩包裹住，所述防火罩包括第一外罩1A和第二外罩，所述的第一外罩1A包括第一顶板11A和从第一顶板11A上凸出的第一环形侧板12A，第一环形侧板12A中间围成第一空腔，第一顶板11A中间开设有第一通孔13A，第一外罩1A安装在注塑外壳20A时，第一顶板11A的底面压在注塑外壳20A的一端面上，第一环形侧板12A内壁面紧贴着注塑外壳20A的外壁面，第二外罩包括第二顶板和从第二顶板上凸出的第二环形侧板，第二环形侧板中间围成第二空腔，第一顶板中间开设有第二通孔，第二外罩安装在注塑外壳时，第二顶板的底面压在注塑外壳的一端面上，第二环形侧板内壁面紧贴着注塑外壳的外壁面。
由于防火罩包裹注塑外壳的端面与轴承支撑架之间还有局部的注塑外壳裸露出来，密封效果差，当电机运行时发生异常导致电机起火后有可能会引燃外部的负载，另外温控器没有受到防火罩的包裹裸露在外，当温控器起火时有可能会引燃外部的负载，整机的防火阻燃效果差。
发明内容：
