ABSTRACT:
The present invention relates to a structure of a stacked stator core formed when rotary motors are manufactured and to a method of manufacturing the stacked stator core. It is possible to improve the workability in the winding process and the productivity of the stator and the rotary motor because the stacked stator core includes a plurality of stator cores300, each of which is made up of a prescribed number of stacked sheet magnetic materials, a plurality of yoke members301forming each stator core, a bendable bent portion304provided between the yoke members, and an interconnecting portion401for connecting the plurality of stator cores300one another while providing a difference in level, by connecting the top end of one stator core with the bottom end of the other stator core.
