【具体实施方式】
如图1所示为根据本发明一实施例的电机定子10,包括支撑座12、固定于支撑座12上的电路板14、以及套接于支撑座12上的电枢16。
请同时参阅图2与图3,所述支撑座12包括底座18、以及由底座18的中央沿轴向一体向外延伸的凸柱20。其中,底座18整体呈扁平圆盘状结构,具有较大的径向尺寸。所述底座18在靠近其外边缘的位置上形成有多个固定柱22,螺钉等固定件穿过固定柱22将电机固定连接于其它相配合的物件上。所述凸柱20呈中空圆筒状,内部设有轴承组件24,用于支撑转子的转动。较佳地,所述轴承组件包括一轴承及一轴承套,所述轴承优选的为滚珠轴承,转子的转轴可转动地插接于轴承组件24内。
所述电枢16套接于凸柱20上,两者之间可以是紧配合等。所述电枢16包括磁芯26、绕设于磁芯26上的绕组28、以及包覆于磁芯26上将磁芯26与绕组28隔离的绝缘架30。
请同时参阅图4,所述磁芯26由导磁材料,如矽钢片等堆叠而成。磁芯26包括环形的轭32、以及由轭32的外缘沿径向向外延伸的若干齿34。所述轭32环套于凸柱20上,将电枢16固定。较佳地,所述凸柱20的外壁面上形成有台阶21,与磁芯26的轭32相抵顶在轴向上定位(见图2)。所述齿34沿轭32的周向均匀间隔设置,每一齿34的径向线端29形成一弧形的齿冠36。所述齿冠36具有较大的周向长度,齿冠36的周向线端29伸出至绝缘架30之外,相邻的齿冠36的线端29之间形成窄小的槽口38,以降低齿槽转矩。
所述绕组28缠绕于磁芯26的齿34上并位于齿冠36的径向内侧,绕组28由漆包线绕制而成。绕组28的线端29与电路板14相连(见图2-3)。优选地,所述电路板14上设有相应的驱动电路,对绕组28供以单相交变直流电。本实施例中,所述电路板14呈扇形,相对于传统的圆环形电路板具有更小的尺寸。在生产制造时,也可以有效利用板材,减少废料的产生。本实施例中,所述底座18上设有对应电路板14的形状、尺寸的切口40(见图3),组装时电路板14嵌设于底座18的切口40位置处,并通过螺钉等固定件固定连接于底座18上。如此,电路板14不会额外占据空间,有效减小定子10以及由其构成的电机的轴向尺寸。
请同时参阅图5,对应于绕组28的线端29,所述电路板14在其外边缘处形成有穿孔42。所述穿孔42为C形,在轴向上贯穿所述电路板14,在周向上则在对应电路板14的外边缘处形成开口44。如此,绕组28的线端29无需经由轴向穿过穿孔42,而是由穿孔42的开口44沿横向滑入至穿孔42内,方便了绕组28与电路板14穿孔42的连接,节省时间。较佳地,所述开口44朝电路板14的外围呈渐开的喇叭状,从而更利于线端29嵌入。在绕组28的线端29滑入穿孔42之后,伸出穿孔42的部分弯折,并通过焊料15与电路板14的表面焊接固定。较佳地,所述焊料为锡。由于绕组28的线端29是穿过穿孔42后弯折拉至与电路板14的表面相连,线端29弯折部分挂靠到电路板14的开口44边缘,能够承担外力的作用,对焊点起到保护作用,可以保证绕组28与电路板14连接的稳定性与安全性。
另外,为避免线端29与电路板14的尖锐的切口直接接触,在所述穿孔42处卡接有保护元件46。如图6所示,所述保护元件46包括本体48以及由本体48延伸的扣钩50。其中,本体48与电路板14的一表面(图示方向为上表面)相叠,扣钩50穿过穿孔42后钩扣于电路板14相对的另一表面(图示方向为下表面),将穿孔42的边缘覆盖。较佳地,所述本体48呈C形或U形。所述保护元件46为绝缘塑料,具有一定的弹性。在与电路板14相组装时,可以通过弹性变形减小尺寸,方便其扣钩50穿过穿孔42;在扣钩50穿过穿孔42之后恢复形变,与电路板14相钩扣将保护元件46固定。绕组28的线端29由开口44滑入穿孔42,绕组28在保护元件46的作用下与电路板14的穿孔42的孔壁相隔离,保证电气安全。较佳地,所述保护元件46与所述线端29接触的部分为光滑的曲面,比如圆弧面,以避免线端29在应力作用下断裂,从而更好地保护线端29,使线端29能够承载更大的外部应力。
图7所示为本发明一实施例的电机60,所述电机60具有图1所示的定子10及一转子70。较佳地,所述电机60为单相外转子电机。所述转子70环绕于定子10外围。定子10和转子70之间形成气隙,所述定子10的齿冠36之间的槽口38的宽度不大于气隙的径向宽度的3倍。
需要说明的是,本发明并不局限于上述实施方式,根据本发明的创造精神,本领域技术人员还可以做出其他变化,这些依据本发明的创造精神所做的变化,都应包含在本发明所要求保护的范围之内。
