附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明一种具体实施方式所提供的角向磨光机的结构示意图；
图2为图1中无刷电机部分的轴向结构示意图。
具体实施方式
本发明的核心是提供一种角向磨光机，该角向磨光机的结构简单紧凑，使用寿命较长，且传动效率较高。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
请参考图1和图2，图1为本发明一种具体实施方式所提供的角向磨光机的结构示意图；图2为图1中无刷电机部分的轴向结构示意图。
在具体实施方式中，本发明所提供的角向磨光机，包括机壳11，机壳11的内部设置有无刷电机和控制器14，所述无刷电机包括电机转轴12，电机转轴12的外端部可联动地套装有输出盘片13，电机转轴12的轴线垂直于输出盘片13的操作面且经过输出盘片13的圆心；电机转轴12的内端外周部同轴套装有转子铁芯121，转子铁芯121的外周面上设置有永磁体122，机壳11的内部还设置有与永磁体122相配合的定子123。工作过程中，永磁体122在定子123的磁场作用下驱动电机转轴12转动，同时带动输出盘片13同轴联动以实现相应的切削切割作业。所述角向磨光机的整体工作结构中无需齿轮等传动结构，整体装配结构简单紧凑，使用寿命较长，且其仅需无刷电机转轴及其相关磁性定、转子配合件即可实现传动机构的减速，有效避免了动力损耗，使得所述角向磨光机的传动效率较高。
进一步地，控制器14设置于机壳11的内部。将控制器14设置于机壳11内部能够进一步提高所述角向磨光机的组件集成度，并使其结构更加紧凑。该控制器能够实现交流电源到直流电的滤波、整流，以及对所述无刷电机的起停、调速控制、过流保护、断电保护和软启动等控制功能。
本实施例中的无刷电机在实际工作中具有以下特点：效率高，电机效率在80％以上；整机使用寿命长，因为没有碳刷和齿轮，使用寿命在1200小时以上；噪音低，噪音值在65db(分贝)左右；体积小，重量轻；具有电流过载保护和突来电保护。
另一方面，定子123包括定子铁芯124、多个缠绕于定子铁芯124内的定子漆包线组125及设置于定子铁芯124内的冷风通道126。通过设置冷风通道43，以便空气流动，有效降低定子漆包线组42的温度，进而提高电流密度，确保本实施例中的无刷电机为高功率密度的无刷电机，即，单位体积的电机产 生的功率较高。
另外，冷风通道126由相邻两个定子漆包线组125之间的间隙及定子铁芯124与转子铁芯121之间的间隙组成。定子漆包线向定子铁芯124上缠绕，形成定子漆包线组125。在缠绕过程中，相邻两个定子漆包线组125之间存在间隙，以供空气流动，相邻两个定子漆包线组125之间的间隙与定子铁芯124与转子铁芯121之间的间隙连通，进一步加强了空气流动，提高了冷却效果。
如下面数据表显示，以定子4的直径为55mm-65mm，定子高度为20mm的无刷电机为例：
表1 现有技术中与本发明的比较数据
Figure PCTCN2014089562-appb-000001
由此可知，本发明实施例提供的无刷电机的尺寸(定子直径及高度)均小于现有技术中的无刷电机的尺寸，但是，功率大于现有技术中的无刷电机的功率，因此，其单位体积的电机产生的功率较高，使得本发明实施例提供的无刷电机为高功率密度电机。
具体地，电机转轴12上同轴套装有冷却风扇15。该冷却风扇15能够在工作过程中为所述无刷电机降温，以保证其主体工作组件的稳定可靠作业。
更具体地，机壳11上具有与所述无刷电机相配合的通风口111。该通风口111能够进一步提高所述无刷电机的冷却效果。
另一方面，电机转轴12与转子铁芯121之间设置有绝缘层127，绝缘层127为环氧树脂管，机壳11为塑料制件。该绝缘层与塑料机壳相互配合形成双重绝缘结构，能够有效保证所述角向磨光机符合相应的绝缘安全要求，并提高其使用安全性。
当然，上述绝缘层为环氧树脂管仅为优选方案，其材质并不局限于上文所述的环氧树脂管，只要是能够满足所述角向磨光机的实际使用需要均可。
更具体地，所述角向磨光机由工频交流电(AC:110-127V/220-240V)驱 动，控制器14中设置有用于交直流转换的滤波整流模块。在实际装配使用过程中，所述角向磨光机是通过滤波整流模块实现交流电到直流电的转化，再输入到电机，这是无刷电机通行的技术方案。
进一步地，输出盘片13为砂轮磨片、金刚石切割片、混凝土切割片中的任一种。当然，该输出盘片13并不局限于上文所述的砂轮磨片、金刚石切割片、混凝土切割片等，工作人员可以根据实际工况需要灵活选择输出盘片13的材质，即，只要是能够满足所述角向磨光机的实际使用需要均可。
更具体地，所述角向磨光机由直流低压电源或电池包驱动。
为了更好地说明本发明中无刷电机应用于角向磨光机后的改进效果，现将角向磨光机应用串激电机和无刷同轴电机的相关资料列入下表：

综上可知，本发明中提供的角向磨光机，包括机壳，所述机壳的内部设置 有无刷电机和控制器，所述无刷电机包括电机转轴，所述电机转轴的外端部可联动地套装有输出盘片，所述电机转轴的轴线垂直于所述输出盘片的操作面且经过所述输出盘片的圆心；所述电机转轴的内端外周部同轴套装有转子铁芯，所述转子铁芯的外周面上设置有永磁体，所述机壳的内部还设置有与所述永磁体相配合的定子。工作过程中，所述永磁体在所述定子的磁场作用下驱动所述电机转轴转动，同时带动所述输出盘片同轴联动以实现相应的切削切割作业。所述角向磨光机的整体工作结构中无需齿轮等传动结构，整体装配结构简单紧凑，使用寿命较长，且其仅需无刷电机转轴及其相关磁性定、转子配合件即可实现传动机构的减速，有效避免了动力损耗，使得所述角向磨光机的传动效率较高。
