Abstract
A stator for an electric motor according to the present disclosure includes a stator core having a plurality of slots and teeth, and a stator coil wound via the plurality of slots, wherein the stator coil includes a plurality of hairpins inserted into the plurality of slots and connected in series with one another, wherein the plurality of hairpins is spaced apart from one another by a partial discharge suppression distance to suppress partial discharge between adjacent hairpins, wherein a partial discharge suppression distance between hairpins with a high voltage distribution ratio is farther than a partial discharge suppression distance between hairpins with a low voltage distribution ratio when power is applied to the stator coil. This may result in suppressing reduction of lifespan of the stator coil due to the partial discharge of the hairpins.
