    • The present invention provides a dynamoelectric stator and a method for the manufacture thereof enabling electrical insulation properties to be improved by forming slot-housed portions with a racetrack-shaped cross section to suppress damage to an electrically-insulating coating arising during mounting of a stator winding to a stator core. The construction is such that the slot-housed portions of the stator winding are formed with the racetrack-shaped cross section, and are housed inside slots so as to line up in single columns in a radial direction with a longitudinal direction of the cross section of the slot-housed portions aligned in a circumferential direction. Thus, because short sides of the slot-housed portions facing inner circumferential side surfaces of the slots form convex curved surfaces, the occurrence of damage to the electrically-insulating coating resulting from rubbing between the short sides of the slot-housed portions and the inner circumferential side surfaces of the slots during insertion of the slot-housed portions into the slots is suppressed, thereby improving electrical insulation properties.
    • 本发明提供一种电动定子及其制造方法,其能够通过形成具有跑道形横截面的狭槽收纳部分来改善电绝缘性能,以抑制在定子绕组安装期间产生的电绝缘涂层的损坏 到定子铁心。 该结构使得定子绕组的狭槽容纳部分形成有跑道形横截面,并且容纳在狭槽内,以沿径向方向排列成单列,其横截面的纵向方向 狭槽收纳部沿圆周方向排列。 因此,由于槽狭槽容纳部的面向槽的内周侧面的短边形成凸曲面,所以由于在狭槽收容部的短边与内侧的内侧之间的摩擦而导致的电绝缘涂层的损伤的发生 抑制了将槽容纳部分插入槽内的槽的圆周侧表面,从而提高了电绝缘性能。

    • The present invention provides a rotor for a rotary electric machine that suppresses the occurrence of winding disturbances in the process of winding a coil wire and has a coil field having a uniform outside diameter that is less likely to collapse.A coil field of a rotor coil is constructed by winding a coil wire having a circular cross section onto an outer circumference of a drum portion of a bobbin in multiple layers so as to make columns in each of the layers equal in number in an axial direction. Odd numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of a first flange portion of the bobbin, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of a second flange portion of the bobbin, and even numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of the second flange portion, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of the first flange portion. The gap S satisfies an expression D/4≦S≦D/2 relative to a diameter D of the coil wire.Thus, because the occurrence of winding disturbances in the process of winding the coil wire is suppressed, the coil wire can be wound into an aligned state, enabling a coil field that is less likely to collapse to be achieved, and the outside diameter of the coil field is made uniform, also preventing damage to an electrically-insulating coating resulting from contact with claw-shaped magnetic poles.
    • 本发明提供一种用于旋转电机的转子,其抑制在卷绕线圈线的过程中卷绕干扰的发生,并且具有不太可能崩溃的具有均匀外径的线圈场。 转子线圈的线圈场是通过将具有圆形横截面的线圈线卷绕到筒管的鼓部分的外圆周上以多层构成的,以使得每个层中的列在轴向上相等 。 绕线圈的奇数层被构造成使得线圈线围绕绕线筒的第一凸缘部分的内周壁表面缠绕围绕鼓部分大约一圈,然后卷绕成多个列 轴线方向使得线圈线的列彼此接触,并且最后一列中的线圈线相对于线轴的第二凸缘部分的内周壁表面形成间隙S,并且偶数层的线圈场 被构造成使得线圈线绕着与第二凸缘部分的内周壁表面接触的鼓部分缠绕大约一圈,然后在轴向方向上缠绕成多个列,使得线圈线 彼此接触,并且最后一列中的线圈线相对于第一凸缘部分的内周壁表面形成间隙S. 间隙S相对于线圈线的直径D满足表达式D / 4 <= S <= D / 2。 因此,由于在线圈绕线过程中卷绕干扰的发生被抑制,所以线圈线可以被卷绕成取向状态,能够实现难以塌陷的线圈场, 线圈场均匀,也防止由于与爪形磁极接触而导致的电绝缘涂层的损坏。
