Abstract

The present disclosure relates to a stator for an electric rotating machine, the stator comprising a stator core comprising teeth and slots, and a stator coil comprising a plurality of hairpins configured to be inserted into the slots of the stator core in a predetermined pattern. Each of the plurality of hairpins comprises a conductor and a coating layer surrounding an outer surface of the conductor. The plurality of hairpins comprise a first hairpin configured to be placed in a first section of the stator coil predetermined from an end to which power is to be input, and a second hairpin placed in a section after the first section. The first hairpin provides better insulation performance than the second hairpin, and the first section has a higher voltage distribution ratio than the section including the second hairpin.
