Abstract
The invention relates to a split modular motor stator iron core which comprises an inner stator iron core and an outer stator iron core, wherein the inner stator iron core and the outer stator iron core are arranged in a split mode. The outer stator iron core is formed by splicing a plurality of outer stator modules divided in the circumferential direction, the outer stator modules are connected to form a crawler-shaped outer stator module strap, corresponding positions on the two end faces of the outer stator module strap are provided with clamping structures clamped with each other respectively to form an annular shape, and a plurality of axial embedding grooves are evenly formed in edges of inner holes along the circumferences. The inner stator iron core comprises a plurality of salient pole portions and connecting rings, the salient pole portions are distributed along concentric circles and arranged in the radial direction, and the connecting rings connect adjacent salient pole portions to form a whole from inner side ends. The inner stator iron core is sleeved with the outer stator iron core. Ends of stator salient poles (204) of the inner stator iron core are embedded in the embedding grooves, so that the inner stator iron core and the outer stator iron core are connected integrally to form the motor stator iron core. The split type structure is adopted for a stator, so a primary winding and a secondary winding can be wound from the outer side of the inner stator iron core directly. The split modular motor stator iron core is simple in structure, low in cost and high in yield.
