Patent ID: 8669683

Claim:
A stator of an electric motor, comprising: a stator core haying a plurality of unit cores; a winding frame coupled to each unit core; and a coil wound on the winding frame, wherein the stator core includes: at least two or more stator core-continuous bodies each having at least two or more unit cores continuously formed as a unitary body, wherein each unit core includes a tooth portion having a coupling slot and a coupling projection formed along both ends thereof and each unit core is continuously connected to adjacent unit core without being separated from each other by means of a connection part which is a continuous portion formed at each of both end portions of the tooth portion, wherein each stator core-continuous body is bent at each connection part and the at least two or more stator core-continuous bodies are fitting-connected to each other by means of the coupling slots formed at one side ends thereof and the coupling projections formed at the other side ends thereof to form the stator core haying a round shape, wherein the winding frame includes: an outer peripheral portion having a connection portion formed at each of both ends thereof; a winding portion on which the coil is wound; and an inner peripheral portion.
