Description
本发明涉及小型电动机定子的结构和定子的制造方法。
先有技术中电动机的定子结构如特开昭52-79207号公报所载,该公报所述的定子,是用板状铁心原材料冲压加工而成,它具有容纳转子的中心孔,在中心孔周围形成环形连接部分,由该环形连接部分构成相互连接的多个齿,把数块这种铁心原材层叠起来形成定子铁心后把定子线圈从该定子铁心的外周绕到齿上,再把定子铁心压入圆筒形的环心里从而构成定子。
这种先有技术的定子,使用环形连接部分,使多量的齿不散乱,定子组装操作方便,但它的问题是这种定子的环形连接部分和齿是同样的材料制成,故齿上的磁漏达至环形连接部分,形成磁桥路,结果降低了电动机的运转效率。
本发明的定子具备带有插转子的插孔的圆形非磁性构件、多个等间隔并放射形地装在该构件上的齿、卷绕在这些齿之间的定子线圈以及套入的架,架在这些齿的外周上连接相邻的齿。
定子的制造方法是,在数块层叠成的定子铁板上,设置多个处于同心圆上的槽,槽上有一个朝向转子转轴的开口,构成定子铁心,然后用非磁性的绝缘性树脂,把该定子铁心槽的内面、定子铁心的两端面及填塞槽开口的构件形成一体;此后形成从定子铁心的外圆连到槽上的缺口,通过该缺口,把定子铁心插入槽里,然后在该定子铁心的外圆上套入架。
使用这种结构的定子及采用这种制造方法的定子,可用非磁性的绝缘性树脂制成的构件,填塞定子铁心上的齿在转子侧的开口,可防止齿的磁漏。
图1是表示本发明的实施例的定子铁板的顶面图。
图2是定型后的定子铁心的顶面图。
图3是图2所示定子铁心的Ⅲ-Ⅲ断面图。
图4是图2所示定子铁心所设置的从外圆到槽的缺口的定子铁心顶面图。
图5是图4所示定子铁心上卷绕定子线圈后的定子铁心的顶面图。
图6是图5所示定子铁心的外圆上套入架后的顶面图。
图7是图5所示定子铁心上套入图6所示的架后构成的定子的顶面图。
下面按附图说明本发明的实例。图1是定子铁板的顶面图,是用冲压加工将定子铁心用的0.5mm左右厚的电铁板冲切而成。图1中,标号1是插转子的孔(转子插入孔),标号2-9是槽,这些槽2-9设置在同心圆上,各有一个朝向转子插孔1的开口10-17,这些开口相当于相邻槽之间的齿26-33的空气隙,因此,为充分保证相邻齿之间的极分离,幅度宽较好,但为提高电动机的运转效率,应尽量窄。
标号18-25是连接部,连接相邻的齿,上述槽2-9便是由相邻的齿和连接部而形成。
把数块这种结构的定子铁板层叠(也可在数个齿上设铆接部,在该铆接部位铆接层叠而成)后,用树脂将上下两端面及槽2-9的内周面定型,此时,所有槽2-9的开口10-17也由树脂定型成一体,由树脂将所有齿的转子插孔侧的一部分固定成形,因此,所有齿的一部分都固定在该树脂上。还因在相邻齿之间的空气隙里插入树脂,树脂在转子插孔侧形成圆筒形。
还有,数块开口相连的电铁板一起层叠,也可加强定子铁心的强度。
图2是定型后的定子铁心的顶面图,图3是图2的Ⅲ-Ⅲ断面图。这些图中,标号34所示部件是用树脂(聚对苯二甲酸丁烯酯、尼龙等单体及玻璃纤维强化物)构成一体的绝缘件,由标号35、36、37、38、39及40所示部分构成,标号35是定子铁心上端面绝缘的部分,标号36是下端面绝缘的部分,标号37、38是槽内绝缘的部分,标号39、40是填塞开口的部分。填塞这些开口的部分围成圆筒形,为转子插孔。
图4是图2所示的定子铁心,切除了连接外圆到槽的缺口41-48(图1所示的连接部18-25的部分)以及树脂的顶面图。其加工方法是:(1)切削加工(定子铁心一面旋转,一面用刀具在每一槽间距上进行切削)。(2)可在每一槽间距上进行冲切加工等,此时避开加工时会产生飞边、毛刺等的地方进行加工,可防止铁心的毛刺。
此时,由填塞槽开口的部分、槽2-9的内周面及上下端面上形成的树脂保持齿26-33,所以连接部18-25即使缺欠,各个齿也不会散乱。
图5是图4所示的定子铁心,铁心上卷绕定子线圈后的顶面图。图中,标号49a-49d是主线圈,标号50a-50d是辅助线圈(本发明用于单相感应电动机上的实例)。定子铁心固定后,把绕线导引器装在缺口41-48处,用高速绕线机直接把这些绕线分别绕到各个齿上。因此,缺口41-48的宽度,只要确保该绕线机可动作即可。此时,如果设置线端销,则各线的始端及终端即可自动绕在线端销上(线的始端及终端分明,线圈容易处理,可实现自动化(机械化))。
图6是图5所示的定子,在其外圆上压入了圆筒形的架,为填塞缺口41-48,它具备向中心突出的突起部52-59。该架51使用的材料和定子铁心相同,即电铁板,经冲压加工后层叠而成。在磁阻较小的位置上设置铆接部,铆接成层叠的电铁板。也可采取焊接若干个突起部52-59的头端,以构成一体。
图7是图5所示的定子铁心,在其外圆上压入图6所的架后,构成的定子的顶面图。此时,架51在各个突起部52-59之间,分别夹持着齿26-33的端头,使各齿定位。
还有,在卷绕定子线圈时,为使卷线不绕到转子插孔里,导引销在各齿的插孔侧端面上和绝缘件构成一体,使定子线圈绕线后的线圈末端易整形。
图8是图7的Ⅷ-Ⅷ断面图,表示定子安上托架并装上转子后的情况。图中,标号101、102是切成两半的架,图7所示的定子装入其中,标号103是转子(笼型转子),转轴104由轴承105、106支承,可自由旋转。
如上所述,本发明的电动机定子,具备带有插转子的插孔的圆形非磁性构件、多个等间隔并放射形地装在该构件上的齿、卷绕在这些齿之间的定子线圈以及套入的架,架在这些齿的外周上连接相邻的齿,所以,定子绕线从定子外圆绕到齿上后,可套入架,不必从转子插孔处齿和齿之间形成的开口上卷绕定子线圈,开口的宽度可减小至不产生磁桥路的程度,以提高电动机的运转效率。更因开口变窄,电动机的填隙相应减小,电动机的振动噪音因而减小。
还有,如上所述,本发明的所述定子的制造方法是,定子铁板上设有多个处于同心圆上的槽,它们各具一个朝向转子转轴的开口,把数块这样的铁板层叠成定子铁心,然后用非磁性绝缘树脂将定子铁心的槽内面、定子铁心的两端面及填塞槽开口的部件构成一体,此后形成从定子铁心的外圆到槽的缺口,通过该缺口,把定子铁心插入槽中,再把架套在该定子铁心的外圆上,所以可从定子铁心的外圆直接卷绕定子线圈,与从内侧(转子插孔侧)直接卷绕定子线圈比较,绕线机不受限制,可高速卷绕定子线圈。
还因各个齿之间的开口里填塞的是非磁性的构件,该开口即使窄,也不会产生磁桥路,减少了磁漏,可提高电动机的运转效率。
更因各齿不会散乱,一直和定子构成一体的状态,所以组装定子的操作简易化。
