联动机构150不限于上述描述的结构，也可以为其他结构。例如，在其他实施例中，联动机构150包括两个直齿条、两个齿条档位、以及齿条复位件。
两个直齿条分别设于主限位件120的两个相对侧面。每个直齿条均具有多个间隔预设间隙、并且朝向同一方向倾斜的棘齿。
两个齿条档位分别设于两个排线限位件140上，并且分别与两个直齿条相配合，以使两个直齿条分别推动两个齿条档位，进而使两个排线限位件140背向转动。
齿条档位的具体结构可以根据不同需求来设计，例如，在其中一个实施例中，齿条档位包括一个基体以及从基体上延伸出的齿部。在其他实施例中，齿条档位为直接从排线限位件140上延伸出的齿部。
齿部的形状也可以根据不同需求来设计，例如，在其中一个实施例中，齿部为方形的直齿，并且直齿的顶部设有倾斜面。在其他实施例中，齿部为弧形的斜齿，并且斜齿的倾斜方向与直齿条的棘齿的倾斜方向相反。
进一步的，每个排线限位件140上设有狭长的通孔143，每个齿条档位通过螺纹紧固件与螺母固定在对应的排线限位件140上；螺纹紧固件穿过通孔143，并且松开螺母后，螺纹紧固件在通孔143内可滑动，以调节齿条档位在排线限位件140上的相对位置。

在图示的实施例中，直齿条上的预设间隙在直齿条的轴向的垂直方向上的最大高度可以根据不同的功能来设计，即，预设间隙的表面至直齿条平行于其长度方向的长轴的最大距离可以设置为不同大小，从而与齿条档位相配合，使两个齿条档位带动所述两个排线限位件140展开不同大小的预设角度。
例如，多个预设间隙包括第一预设间隙及第二预设间隙，第一预设间隙在直齿条的轴向的垂直方向上的最大高度与第二预设间隙在直齿条的轴向的垂直方向上的最大高度不相同，并且第一预设间隙与第二预设间隙交替设置。
假设第一预设间隙在直齿条的轴向的垂直方向上的最大高度小于第二预设间隙在直齿条的轴向的垂直方向上的最大高度，当直齿条移动第一预设轴向距离，齿条档位的齿部抵接在第一预设间隙上时，两个排线限位件140刚好抵接在主限位件120的两个相对侧面，从而对第一层绕组件进行排布；当直齿条移动第二预设轴向距离，齿条档位的齿部抵接在第二预设间隙上时，由于第二预设间隙在直齿条的轴向的垂直方向上的最大高度大于第一预设间隙在直齿条的轴向的垂直方向上的最大高度，使得两个齿条档位分别带动两个排线限位件140转动，从而使两个排线限位件140展开预设角度，进而对位于第一层绕组线的上的第二组绕组线进行排布。
在其他实施例中，多个预设间隙包括第一预设间隙、第二预设间隙以及第三预设间隙，第一预设间隙、第二预设间隙、以及第三预设间隙在直齿条的轴向的垂直方向上的最大高度各不相同，并且第一预设间隙、第二预设间隙、以及第三预设间隙依次交替设置。
假设第二预设间隙在直齿条的轴向的垂直方向上的最大高度大于第一预设间隙在直齿条的轴向的垂直方向上的最大高度，小于第三预设间隙在直齿条的轴向的垂直方向上的最大高度，当齿条档位的齿部抵接在直齿条的第一预设间隙上时，两个排线限位件140对第一层绕组件进行排布；当齿条档位的齿部抵接在直齿条的第二预设间隙上时，两个排线限位件140对第二层绕组件进行排布；当齿条档位的齿部抵接在直齿条的第三预设间隙上时，两个排线限位件140对第三层绕组件进行排布。

另外，主限位件120可以在单一滑动方向上才带动两个排线限位件140。例如，在图示的实施例中，主限位件120朝向远离承载体110的方向滑动时，带动两个排线限位件140背向转动。
在其他实施例中，主限位件120朝向靠近承载体110的方向滑动时，带动两个排线限位件140背向转动。

（2）上述限位装置100的主限位件120通过联动机构150带动两个排线限位件140转动，使得采用一个控制单元同时控制两个限位件，减少了额外的控制单元，降低了运动传动的精度要求。
（3）上述联动结构可使两个排线限位件140稳定地处于不同的转动位置，以方便对不同层的绕组线进行排布。
（4）上述限位装置100的主限位件120可以在单一滑动方向带动两个排线限位件140转动，提高了传动的精确度，并且降低了联动结构的使用次数，从而增大了联动机构150的使用寿命。
基于上述绕线机10，本发明还提供一种电机的绕线方法。
请一并参阅图10，本实施方式的电机的绕线方法，包括如下步骤S501~S504。
步骤S501，提供上述的绕线机10。
绕线机10的具体结构如上述描述，在此不再详细赘述。
步骤S502，将电机的待绕线部件20放置在定位件200上，待绕线部件20包括多个间隔设置的绕线柱21，并且多个绕线柱21之间形成绕线槽23。

步骤S504可以采用不同的方式来实现，例如，若需要单个绕线柱21上需要排列多层绕组线，则步骤S504可以进一步包括如下步骤：
绕线装置300将绕组线围绕限位装置100缠绕，并通过排线限位件140依次排列一层；
改变两个排线限位件140之间的间距，绕线装置300通过排线限位件140在一层绕组线上再排列一层绕组线。
若需要连续对多个绕线柱21进行绕线，则所述电机的绕线方法还包括步骤S505~S507。
步骤S505，缠绕完成绕线柱21之后，改变绕线部件与主限位件120的相对位置，使另外一个待绕线的绕线柱21与主限位部121件的限位部121配合。
在本实施例中，转动定位件200，使待绕线部件20跟随定位件200一起转动，直至另外一个待绕线的绕线柱21与限位装置100的主限位件120的限位部121相对，然后，驱动件驱动限位装置100，使主限位件120的限位部121与待绕线部件20的绕线柱21相配合，以限位该待绕线的绕线柱21。

步骤S507，重复步骤S505及S506，直至所有待绕线的绕线柱21均完成绕线动作。
以下以电机的定子为例，并且结合附图具体说明本实施方式的电机的绕线方法。
首先，如图3所示，将无刷电机的定子的绕线柱21与限位装置100的主限位件120的限位部121配合，以限位该无刷电机的定子的绕线柱21。
接着，如图4所示，定子的绕线柱21相对于限位装置100靠近平移，使绕线柱21推动限位装置100的主限位件120，主限位件120朝向承载体110的内部滑动，直至绕线柱21的最内侧与限位装置100的两个排线限位件140的卡持凸起142的最外侧平齐，两个排线限位件140的卡持凸起142与主限位件120的相对两侧面接触。
接着，如图5所示，定子的绕线柱21相对于限位装置100远离平移，使绕组线从绕线柱21的内侧向外侧逐步缠绕在绕线柱21上，形成第一层绕组线。
接着，如图6所示，当定子的绕线柱21相对于限位装置100继续远离平移，直至限位装置100的主限位件120伸出两个排线限位件140的外侧时，主限位件120上的两个棘153同时与两个棘轮151抵接，而带动两个棘轮151转动。两个棘轮151相对于棘轮档位155转动，使棘轮档位155抵接在棘轮151的第二预设间隙上，棘轮151的第二预设间隙相对于棘轮151的轴心的半径大于第一预设间隙相对于棘轮151的轴心的半径。两个排线限位件140相对张开预设角度。
接着，如图7所示，定子的绕线柱21相对于限位装置100靠近平移，使绕线柱21推动限位装置100的主限位件120，主限位件120朝向承载件的内部滑动，直至绕线柱21的最外侧与限位装置100的两个排线限位件140的卡持凸起142的最外侧平齐，两个排线限位件140的卡持凸起142与绕线柱21上的第一层绕组线接触。同时，绕组线从绕线柱21的内侧向外侧逐步缠绕在绕组柱A上，形成第二层绕组线。
接着，如图8所示，定子的绕线柱21相对于限位装置100远离平移，直至绕线柱21的最内侧与限位装置100的两个排线限位件140的卡持凸起142的最外侧平齐。
最后，如图9所示，当定子的绕线柱21相对于限位装置100继续远离平移，限位装置100的主限位件120伸出两个排线限位件140的外侧时，主限位件120上的两个棘153同时与两个棘轮151抵接，而带动两个棘轮151转动。两个棘轮151相对于棘轮151档位转动，使棘轮档位155抵接在棘轮151的第一预设间隙上，两个排线限位件140与主限位件120的两个相对侧面接触。
若需要对另外一个绕线柱21进行绕线，则重复上述步骤。
