Description

一种适用于空心杯电机的双层绕组及其制作方法 技术领域
本发明涉及一种电机绕组，尤其是涉及一种适用于空心杯电机的双层绕组及其制作方法。
背景技术
空心杯电机相对于传统有齿槽电机具有无齿槽效应，使得电机无齿槽转矩，反电势无齿谐波，上述因素有效的降低了电机运行时的转矩脉动。另外，无齿槽电机转子通常具有低惯量，电机运行转速高等特点。因此，该类型电机广泛应用于高精度的机器人关键电机，医疗器械，电动工具等等行业中。
无齿槽电机的结构见图1，其中1为前端盖，2为后端盖，3为外壳，4为轴承，5为霍尔传感器，6为定子，7为转子，8为绕组，9为转轴。绕组8的三相绕组与定子6的内壁通过胶水固定。
为了使电机工作于不同的电压等级下可以改变绕组的匝数，实现电压的兼容。当绕组匝数需求上升时，由于绕组导体按照三相120°相带均匀分布于定子内壁中，当匝数增加时，会导致导体的线径下降。如果仍然采用单层的方案不能有效利用电机的径向空间。因此需要采用双层绕组，增加电机的导体，降低绕组电阻，提升电机的电磁性能。
目前，无齿槽电机的自动绕线机一般只能实现奇数层的绕组，通常为1层，3层。对于空心杯双层绕组的方案一般先在绕线模具(绕线模一般为六边形或者菱形)上依次绕制A1-B1-C1-A2-B2-C2(其中A1，B1，C1分别为一层三相绕组，A2，B2，C2为另外一层三相绕组)，之后将绕制好的绕组脱模，热压板平，最后卷制成一个两层绕组。但是，该方法卷制过程复杂，内层绕组以卷圆芯棒成圆，外层绕组以卷制成圆的内层绕组为基准成圆，绕组成圆后容易积累误差，引起绕组尺寸偏差。
