Description

一种干衣机用的BLDC驱动一体式电机 技术领域
本PCT属于电机技术领域，尤其是涉及一种干衣机用的BLDC驱动一体式电机。
背景技术
目前有些干衣机使用感应电机或者BLDC电机，BLDC电机即无刷直流电机，该电机克服了有刷直流电机的先天性缺陷，以电子换向器取代了机械换向器，定子产生的磁场与转子产生的磁场具有相同的频率。但是BLDC电机的驱动控制部分安装在后端盖的内部，驱动控制部分由于电子元件较多极易损坏，维修驱动控制部分需要把后端盖拆卸后再维修，这样造成维修不便，并且驱动控制部分损坏了往往需要整个更换，若能够把驱动控制部分与电机分开安装，驱动控制部分不再安装在后端盖内部，这样后续的维修方便。
PCT内容
本PCT是为了解决BLDC电机的驱动控制部分安装在后端盖的内部，后续维修不方便的问题，提供了一种干衣机用的BLDC驱动一体式电机。
本PCT采用的技术方案如下：
一种干衣机用的BLDC驱动一体式电机，包括定子、转子、前端盖、后端盖和转轴，所述转轴依次穿过前端盖、转子、后端盖、底板和外壳，所述转子包括永磁体，所述转子的外侧装有定子，所述后端盖外侧安装底板，所述底板上设有驱动器模块，用外壳罩住驱动器模块并通过螺栓与底板、后端盖固定在一起。该BLDC电机通过底板上安装驱动器模块，再用外壳罩住驱动器模块，这样在维修时不再需要拆开电机的后端盖，只需要把外壳拆卸，然后在底板上维修驱动器模块，若是驱动器模块损坏严重是可以直接拆卸底板，再安装一个新的具有驱动器模块和外壳的底板，这样维修方便、快捷。
进一步地，所述定子包括定子铁芯，所述定子铁芯包括定子冲片直线条形冲压形成的圆形结构，所述定子铁芯由若干的铁芯分部构成，所述铁芯分部的左侧设有一个凸形圆，铁芯分部的右侧设有一个凹形圆，凸形圆和凹形圆连接。目前的现有技术中定子冲片大多采用扇形定子冲片，材料利用率只有36％，采用直线条形冲压即在一块硅钢片上冲压12个定子冲片槽，冲压后叠压再弯圆，这样材料利用率可以提高到67％。
进一步地，所述驱动器模块上的散热块通过导热胶固定，并且通过外壳罩住散热块固定。导热胶在这里具有两个作用：一是具有粘性，沾住散热块；二是具有导热作用。外壳还能顶住散热块，防止散热块移位。
进一步地，所述底板和外壳均是由塑料制成的圆形壳体。圆形壳体提高空间利用率，并且在外壳上需要设有通风口和插件槽，塑料成型的工艺简便。塑料不导电，若是由铝制成会导致漏电的风险，并且插件插进插件槽在铝制的条件下需要6mm的安全距离，而铝制的外壳往往需要灌胶，灌胶之后就不能保证6mm的安全距离，因此在这里用塑料制成底板和外壳。
进一步地，所述底板和外壳的四周均设有若干条三角凹槽，所述底板的三角凹槽内设有空心三角柱，所述外壳上对应空心三角柱的位置设有实心三角柱。在安装时外壳的实心三角柱插入底板上的空心三角柱来定位、固定外壳。
进一步地，所述后端盖和前端盖与定子都通过卡槽连接，所述后端盖与前端盖用螺栓固定。后端盖和前端盖与定子的连接处直径都大于定子，这样定子可以卡入前端盖和后端盖。
进一步地，所述前端盖、后端盖、外壳上都设有若干个通风口。通风口有利于电机本体和驱动器模块的散热。
进一步地，所述外壳的侧部设有插件槽。插件槽用于插插件。
进一步地，所述定子铁芯的磁极端部设有防脱落结构，该防脱落结构呈U型。在安装电机时在定子铁芯上缠绕线圈，防脱落结构可以防止线圈脱落。
本PCT具有以下有益效果：该BLDC电机采用驱动与电机一体的一体机即通过底板上安装驱动器模块，再用外壳罩住驱动器模块，这样在维修时不再需要拆开电机的后端盖，只需要把外壳拆卸，然后在底板上维修驱动器模块，若是驱动器模块损坏严重是可以直接拆卸底板，再安装一个新的具有驱动器模块和外壳的底板，这样维修方便、快捷；定子冲片采用直线条形冲压后绕线圈再弯圆的工艺可以把材料利用率从扇形定子冲片的36％提高到67％；驱动器模块上的散热块通过导热胶固定，并且通过外壳罩住散热块固定。

具体实施方式
下面结合附图和实施例对本PCT进行详细阐述。
实施例：如图1至图5所示，一种干衣机用的BLDC驱动一体式电机，包括定子5、转子12、前端盖4、后端盖6和转轴1，所述转轴1依次穿过前端盖4、转子12、后端盖6、底板7和外壳3，所述转子12包括永磁体，所述转子12的外侧装有定子5，所述后端盖6外侧安装底板7，所述底板7上设有驱动器模块9，用外壳3罩住驱动器模块9并通过螺栓与底板7、后端盖6固定在一起。该BLDC电机采用驱动与电机一体的一体机即通过底板7上安装驱动器模块9，再用外壳3罩住驱动器模块9，这样在维修时不再需要拆开电机的后端盖6，只需要把外壳3拆卸，然后在底板7上维修驱动器模块9，若是驱动器模块9损坏严重是可以直接拆卸底板7，再安装一个新的具有驱动器模块9和外壳3的底板7，这样维修方便、快捷。
所述定子5包括定子铁芯17，所述定子铁芯17包括定子冲片直线条形冲压形成的圆形结构，所述定子铁芯17由若干的铁芯分部构成，所述铁芯分部的左侧设有一个凸形圆，铁芯分部的右侧设有一个凹形圆，凸形圆和凹形圆连接。由定子冲片先采用直线条形冲压形成单层定子铁芯片，冲压之后若干个单层定子铁芯片压叠成定子铁芯17，然后在定子齿极16上绕线圈，之后把条形的定子铁芯17弯成圆形，最后定子注塑。目前的现有技术中定子冲片大多采用扇形定子冲片，材料利用率只有36％，采用直线条形冲压即在一块硅钢片上冲压12个定子冲片槽，冲压后再弯圆，这样材料利用率可以提高到67％。把多块冲压后的硅钢片压叠而成后再弯圆。
单层定子铁芯片具有12个T型的铁芯分部，铁芯分部的上部呈圆弧形，每个铁芯分部之间上表面呈凹形，每个铁芯分部的左侧设有一个凸形圆，凸形圆半径为0.8mm，每个铁芯分部的右侧设有一个凹形圆，凹形圆半径为0.8mm，凸形圆和凹形圆连接并且下部设有30度的过渡角。凸形圆和凹形圆连接并且下部设有过渡角，铁芯分部的上部呈弧形，这样使条形的定子铁芯弯成圆形并且第一个铁芯分部与最后一个铁芯分部连接。
所述驱动器模块9上的散热块11通过导热胶固定，并且通过外壳3罩住散热块11固定。导热胶在这里具有两个作用：一是具有粘性，沾住散热块；二是具有导热作用。外壳3还能顶住散热块11，防止散热块11移位。
所述底板7和外壳3均是由塑料制成的圆形壳体。圆形壳体提高空间利用率，并且在外壳3上需要设有通风口和插件槽，塑料成型的工艺简便。塑料不导电，若是由铝制成会导致漏电的风险，并且插件插进插件槽在铝制的条件下需要6mm的安全距离，而铝制的外壳往往需要灌胶，灌胶之后就不能保证6mm的安全距离，因此在这里用塑料制成底板和外壳。
所述底板7和外壳3的四周均设有若干条三角凹槽，所述底板7的三角凹槽内设有空心三角柱2，所述外壳3上对应空心三角柱2的位置设有实心三角柱10。在安装时外壳3的实心三角柱10插入底板7上的空心三角柱2来定位、固定外壳3。通过空心三角柱和实心三角柱的插接实现外壳的精准快速定位，取消螺丝固定提高安装效率，降低成本。
所述后端盖6和前端盖4与定子5都通过卡槽13连接，所述后端盖6与前端盖4用螺栓固定。后端盖6和前端盖4与定子5的连接处直径都大于定子5，即前端盖4和后端盖6开合处呈一台阶样式，这样定子可以卡入前端盖4和后端盖6。
所述前端盖4、后端盖6、外壳3上都设有若干个通风口14。通风口14的设计有利于电机本体和驱动器模块9的散热。
所述外壳3的侧部设有插件槽15。插件槽15用于插插件。
所述定子铁芯的磁极端部设有防脱落结构8，该防脱落结构呈U型。在安装电机时在定子铁芯上缠绕线圈，防脱落结构8可以防止线圈脱落。
