    • Disclosed is a method for sheathing an armature (14) for electric machines (10), in which a stack of lamellae (18) that is equipped with grooves (46) for armature windings (20) is mounted on an armature shaft (16) by means of a bore (36) and is provided with at least one groove insulation (48) with the aid of the sheathing process. The plastic flows through ducts (42) that extend along the bore (36) of the stack of lamellae (18) and the surface of the armature shaft (16). The plastic is molded in only on a first face (38) of the stack of lamellae (18), from which the plastic flows into the grooves (46) and through the ducts (42). The plastic invades the grooves (46) also from the second face (40) after being discharged from the ducts (42) on said second face (40) and converges with the plastic discharged from the first face (38). The inventive method has the advantage of technically implementing fixing and insulation of the grooves of the stack of lamellae of an armature of an efficiency-optimized small electric motor or electric machine while the groove insulation is provided with a minimum layer thickness for such sheathings at the bottom thereof in order to allow for maximum copper fillings.
    • 公开了一种用于电动机(10)的电枢(14)的覆盖方法,其中在电枢轴(16)上安装有用于电枢绕组(20)的具有凹槽(46)的薄片层(18) 借助于孔(36)并且借助于护套工艺设置有至少一个凹槽绝缘体(48)。 塑料流过沿着薄片堆叠(18)的孔(36)和电枢轴(16)的表面延伸的管道(42)。 塑料只在薄片堆叠(18)的第一面(38)上成型,塑料从该薄片塑料流入凹槽(46)并通过导管(42)。 在从第二面(40)上的管道(42)排出之后,塑料也从第二面(40)侵入凹槽(46),并与从第一面(38)排出的塑料会聚。 本发明的方法具有技术上实现效率优化的小型电动机或电机的电枢的层叠体的槽的固定和绝缘的优点,同时在这种槽的绝缘层具有这样的护套的最小层厚度 的底部,以允许最大的铜填充。
