Description

轭绕组罩极电动机 技术领域
本发明涉及一种罩极交流单相电机。具体是电枢绕组围绕定子铁芯的轭部绕制形成轭部绕组，通入单相交流电，轭部绕组形成轭部磁通聚集形成齿部磁通经过罩极形成转动定子磁场，这就是轭绕组罩极电动机。
背景技术
电机的部件包括定子、转子、电极、支承部件和机壳等。电机一般是圆柱状转子位于电机中心内部、圆环状定子位于外部包围转子，这是内转子电机。拓扑技术可以对应实现圆柱状定子位于电机中心内部，圆环状转子位于外部包围定子，这是外转子电机。所述拓扑技术是成熟技术。改进电机的关键部件定子，就可以改进电机。传统罩极电机，围绕定子铁芯的齿部绕制电枢绕组，在齿部设置罩极，电枢绕组形成的交变齿部磁通经过罩极形成转动定子磁场，实现启动、加速和运行；由于齿部周围空间有限，电枢绕组比较拥挤，需要较高的齿部高度。本发明提出改进定子的结构，电枢绕组围绕定子铁芯的轭部绕制，形成轭部绕组，通入单相交流电，轭部绕组形成轭部磁通在齿部聚集形成交变齿部磁通，交变齿部磁通经过罩极形成转动定子磁场，驱动电机转子。所述交变齿部磁通经过罩极形成转动定子磁场是成熟技术。
本发明提出采用轭部绕组的定子新结构，用于改进罩极电机。由于定子铁芯的轭部空间非常宽余，而且轭部绕组中平行于电机轴的一部分电线围绕在轭部的外侧，电枢绕组不拥挤，可以降低齿部高度，这样可以减小电机的自重，提高电机效率。电机行业需要本发明轭绕组罩极电动机。
发明内容
本发明轭绕组罩极电动机，由定子、转子、电极、支承部件和机壳等部件组成。特征在于：电枢绕组围绕定子铁芯的轭部绕制形成轭部绕组，通入单相交流电，轭部绕组形成轭部磁通，轭部磁通聚集形成齿部磁通，齿部磁通经过罩极形成转动定子磁场。
定子由定子铁芯和电枢绕组组成。定子铁芯采用成熟技术采用高磁通材料制造，例如采用硅钢、层叠硅钢等制造。根据需要设置定子铁芯，使各个齿部沿圆周方向均匀布置向内朝向转子，轭部平行于转子运动方向呈圆环状，轭部连接各个齿部形成定子铁芯。齿部数等于于定子极对数乘以2，在每个齿部的半个齿部设置罩极线圈，每个罩极线圈的设置方向相同， 设置了罩极线圈的齿部是罩极。所述罩极线圈和在齿部的半个齿部设置罩极线圈是成熟技术。
电枢绕组采用电线围绕定子铁芯轭部绕制形成轭部绕组，沿定子铁芯轭部分段设置。本发明中电枢绕组标示为a相、a′相和a″相等。各段轭部绕组的正负按轭部定向方法确定：平行于转子运动方向选定一个定子铁芯截面，设该截面图中顺时针方向为轭部磁通正向，即当轭部磁通的N极方向顺时针时该段轭部磁通为正向轭部磁通，当轭部磁通的N极方向逆时针时该段轭部磁通为负向轭部磁通。按右手螺旋定则，流通正电流时形成正向轭部磁通的轭部绕组为正轭部绕组，流通正电流时形成负向轭部磁通的轭部绕组为负轭部绕组，流通负电流时形成正向轭部磁通的轭部绕组为负轭部绕组，流通负电流时形成负向轭部磁通的轭部绕组为正轭部绕组。各段轭部绕组通入单相交流电，在被围绕的轭部形成轭部磁通，每一段轭部中的轭部磁通只有一种方向，或磁通为零。相邻的同向轭部磁通相互串联，相邻的异向轭部磁通相互聚集。聚集在最邻近的齿部形成齿部磁通。相邻的同向轭部磁通相互串联形成一组轭部磁通，在一组轭部磁通头部(N极一端)最邻近的齿部形成正向齿部磁通，在一组轭部磁通尾部(S极一端)最邻近的齿部形成负向齿部磁通。两组轭部磁通相邻的头部聚集在最邻近的齿部形成正向齿部磁通，两组轭部磁通相邻的尾部聚集在最邻近的齿部形成负向齿部磁通。随着单相交流电电相位变化，形成的齿部磁通变化，形成交变齿部磁通，交变齿部磁通经过罩极形成转动定子磁场；可以驱动转子启动、加速和运行。N极是北极，S极是南极，*是乘号，/是除号，+是正号，-是负号。
轭部绕组设置方式为：定子极对数为1时，定子铁芯有二个齿部和二段轭部，在轭部上沿顺时针方向依次设置二段轭部绕组，即a相正轭部绕组(+a)和a相负轭部绕组(-a)，如图1。定子极对数为2时，定子铁芯有四个齿部和四段轭部，在轭部上沿顺时针方向依次设置四段轭部绕组，即a相一号正轭部绕组(+a)、a相一号负轭部绕组(-a)、a相二号正轭部绕组(+a′)和a相二号负轭部绕组(-a′)。定子极对数为更多时，轭部绕组设置方式依此类推。
通入相同频率的单相交流电，当定子极对数为Q时，转动定子磁场转速是定子极对数为1时转动定子磁场转速的1/Q。Q为不小于2的自然数。
转子是感应转子，包括笼形感应转子和绕线式感应转子。笼形感应转子由转子轴、转子铁芯和笼形绕组组成，笼形绕组由前端环、导条和后端环组成。绕线式感应转子由转子轴、转子铁芯和绕线式绕组组成。所述转子轴可以是实心结构、非实心结构。本自然段所述均是成熟技术。
电极是电机的电线接口。支承部件包括支座、支架、轴和轴承等。机壳是电机外围的支撑和保护部件。电极、支承部件和机壳采用成熟技术。
具有一对极对数的轭绕组罩极电动机剖面图参见图1，图中大括号指示各段轭部绕组的相应相位序号；所述相位序号是标示交流电绕组的成熟技术。图中3是罩极，4是罩极线圈，图中的罩极线圈均设置于罩极的逆时针侧半个齿部，5是感应转子的转子铁芯，6是笼形感应转子的导条。图1中电机的电路简图参见图2。图2中各轭部绕组之间的相对位置与图1中的相同。
传统罩极交流单相电机，电枢绕组都围绕定子铁芯的齿部绕制，具有传统的齿部绕组形成交变齿部磁通最终形成转动定子磁场的运行机制。轭绕组罩极电动机，电枢绕组围绕定子铁芯的轭部绕制，这是对结构的创新，本说明书对电枢绕组设置方式已经详细描述；各轭部绕组形成轭部磁通聚集形成交变齿部磁通最终形成转动定子磁场，这是对运行机制的创新。轭绕组罩极电动机，有益之处还在于：由于轭部磁通聚集形成齿部磁通的聚磁效应，形成转动定子磁场的效率较高。由于电枢绕组的一部分围绕在定子铁芯轭部的外侧，定子铁芯需要的齿部高度较矮，自重较轻。本发明创新了定子的结构和运行机制，减小了自重，提高了效率。在此之前没有相同的电机。本发明的描述以径向磁通内转子电机为例，本发明也包括径向磁通外转子电机、轴向磁通电机和直线电机等，业内技术人员可利用拓扑技术轻易推导出来。
上述给不同的绕组相位序号加“′”一撇或加“″”二撇标示为成熟技术，原本应用于传统电机的各齿部绕组相位序号，在本发明中也应用于各段轭部绕组相位序号。a、a′和a″表示电枢绕组的或正或负的不同段轭部绕组。当定子具有一对极对数时，“′”和“″”不出现。当定子具有二对极对数时，“′”出现。当定子具有三对极对数时，“′”和“″”均出现。上述通入单相交流电为成熟技术。所述定子铁芯、转子铁芯、高磁通材料、轭部、齿部、齿部高度、齿部磁通、罩极、聚集、交变定子磁场、转动定子磁场和极对数均为成熟技术。所述电线、电枢绕组、齿部绕组、绕制、正极、负极、连接和电相位均为成熟技术。

    定子由定子铁芯和电枢绕组组成，定子铁芯采用成熟技术，包括齿部和轭部；齿部数等倍于定子极对数乘以2，在每个齿部的半个齿部设置罩极线圈，每个罩极线圈设置的方向相同，设置了罩极线圈的齿部是罩极；
    电枢绕组采用电线围绕定子铁芯轭部绕制形成各段轭部绕组，沿定子铁芯轭部分段设置，各段轭部绕组的正负按轭部定向方法确定；各段轭部绕组通入单相交流电，在被围绕的轭部形成轭部磁通，每一段轭部中的轭部磁通只有一种方向，或磁通为零；相邻的同向轭部磁通相互串联，相邻的异向轭部磁通相互聚集，聚集在最邻近的齿部形成齿部磁通；相邻的同向轭部磁通相互串联形成一组轭部磁通，在一组轭部磁通头部(N极一端)最邻近的齿部形成正向齿部磁通，在一组轭部磁通尾部(S极一端)最邻近的齿部形成负向齿部磁通；随着单相交流电电相位变化，形成的齿部磁通变化，形成交变齿部磁通，交变齿部磁通经过罩极形成转动定子磁场，可以驱动转子启动、加速和运行；
    轭部绕组设置方式为：定子极对数为1时，定子铁芯有二个齿部和二段轭部，在轭部上沿顺时针方向依次设置二段轭部绕组，即a相正轭部绕组(+a)和a相负轭部绕组(-a)；定子极对数为2时，定子铁芯有四个齿部和四段轭部，在轭部上沿顺时针方向依次设置四段轭部绕组，即a相一号正轭部绕组(+a)、a相一号负轭部绕组(-a)、a相二号正轭部绕组(+a′)和a相二号负轭部绕组(-a′)；定子极对数为更多时，轭部绕组的设置方式依此类推；
    转子是感应转子，包括笼形感应转子和绕线式感应转子；
    转子、电极、支承部件和机壳采用成熟技术。
