Description

空心电动机
所属技术领域
本发明是一种空心节能电动机。
背景技术：
1、现有的内转子电动机，动力发力点在定子与转子之间，动力传动都是从内转子旋转发力点向中心轴旋转传送，再从中心轴向传动轮外沿传送，向外传送过程中存在着从轴心到传动轮边沿的力臂动力损耗，传动轮直径越大，动力传送的损耗也越大，中心轴受到的扭力就越大，对中心轴生产材料的品质要求也越高。
2、现有电动机的散热系统，是在电动机一端的中心轴上安装螺旋扇叶，在金属机体外壳上设置散热导流槽，中心轴旋转，带动螺旋扇叶旋转作功而产生风力，在导流罩的作用下，用风力对电机外壳上的导流散热槽进行散热，设置机体散热导游槽，增加了机体材料也增大了机体体积和重量，却不能解决电动机内部发热的问题。
3、使用中心轴上安装螺旋扇叶散热，使电动机只能设置一个传动轮，失去了另一端进行动力传送的功能。
4、内转子采用实心轴设计，内转子使用材料多、质量大，启动功耗大，启动和制动时间长。
发明内容：
1、内转子空心电动机，内转子中心部位成空心圆筒形状，在空心圆筒内壁上，向轴心方向焊接或连接内螺旋叶片。
2、内转子空心圆筒两端伸出转子压片内套装的密封轴承，两端伸出部分构成空心传动轮。
3、外转子空心电动机，外转子外沿中间部位成为动力传动轮，外转子压片外沿超出外转子外沿，超出部分呈螺旋扇叶形状，形成外散热叶片。
4、内定子中心部位呈空心圆筒状，空心圆筒内壁上设置内散热片，两端超出转子压片内的密封轴承，超出部分连接固定机座和安装电源接线盒。

附图5：外转子电机外观正面结构图，图中(11)空心内定子散热片。
具体实施方式
1、内转子空心电动机运行时，内转子空心圆筒(7)旋转，带动内壁上的内螺旋叶片(6)旋转，产生对空气的挤压力，推动空气在空心圆筒(7)内快速流动，在散热导流罩(8)的作用下，形成散热气流，对机体内部和外部进行散热。
2、内转子空心电动机旋转，内转子空心圆筒(7)两端伸出转子压片(3)的部分作为动力输出的空心传动轮(2)向外传送动力。
3、外转子电动机运行时，外转子旋转成为动力传动轮(10)，两端的外散热叶片(9)与内定子空心筒内的散热片(11)同时散热。
