Abstract
The utility model relates to a split-type motor stator iron core including an inner stator iron core and an annular outer stator iron core arranged in a split form. The inner stator iron core includes salient pole single sheets and salient pole annular sheets. The salient pole annular sheets include a plurality of salient pole parts in the shape identical to that of the salient pole single chips and distributed in concentric circles and arranged in a radial direction, and an annular connection part connecting the adjacent salient pole parts with each other integrally from an inner side end. The quantity of the salient pole parts is identical to the quantity of engaging ports and the salient pole parts are distributed uniformly in the circumferential direction. The inner stator iron core is formed by overlapping salient pole annular sheet layers and the salient pole single sheet layers alternately. The outer stator iron core and the inner stator iron core are connected together integrally in an engaged manner. By adopting the split-type structure for a stator, a main winding and an auxiliary winding can be made by adopting a directly winding method with high efficiency and high yield. And slot ports are only in local connection, so that no cut is needed and motor performance is not affected.
