Abstract
The present invention relates to a stator of a rotating electric machine, including: a stator core having a plurality of slots; and a stator coil configured by connecting a plurality of conductor segments including: one or more first-type conductor segments each having a conductor and a first sheath part surrounding and insulating an outer surface of the conductor; and one or more second-type conductor segments each having the conductor, the first sheath part, and a second sheath part surrounding and insulating a part of an outer surface of the first sheath part, wherein each of the conductor segments includes two insertion parts configured to be inserted into different slots among the plurality of slots; a crown part connecting respective first ends of the two insertion parts; and welding parts extending from respective second ends of the two insertion parts to be connected by welding, and wherein the second-type conductor segment is disposed in a section having a relatively high voltage distribution ratio. Therefore, during high voltage application, partial discharge can be prevented.
