Zusammenfassung:	The present invention relates to a stator coil structure of a generator. The stator coil structure of a generator comprises: a stator bar arranged in a slot unit formed in a stator core and having a hollow unit formed inside; and a plurality of strands arranged inside the hollow unit. According to the present invention, the plurality of strands arranged inside the stator bar are alternately arranged with non-insulated strands and insulated strands so as to maintain an insulation effect and reduce a winding resistance by increasing a cross-sectional area of a strand conductor. 본 발명은 발전기의 고정자 코일 구조에 관한 것으로, 고정자코어에 형성된 슬롯부에 배치되고, 내부에 중공부가 형성된 고정자바 및 상기 중공부의 내부에 배치되는 복수개의 소선를 포함한다. 본 발명에 따르면, 고정자바의 내부에 배치되는 복수개의 소선을 비절연된 소선과 절연된 소선으로 교대로 배치하여, 절연효과를 유지함과 동시에 비절연된 소선 전도체의 단면적을 증가시켜 권선저항을 감소시키는 효과를 기대할 수 있다.
