Abstract: A stator cooling device includes a stator plate including a plurality of stator coils, the stator plate being disposed with a main flow path including a connection flow path that extends toward an internal side of the state plate in a radius direction of the state plate. Furthermore, the stator cooling device includes at least one pair of cooling flow paths stacked on the stator plate along an axial direction of the stator plate and having different structures. The pair of cooling flow paths is configured to guide a fluid introduced through the main flow path to the connection flow path disposed adjacent to each of the cooling flow paths.

Abstract: A motor for a vehicle, such as an electric vehicle, includes a stator having a plurality of coils wound thereon, and a heat spreader positioned on a cross-section of the stator. The stator coils of the stator are configured to effectively cool an internal part of the stator without a complicated structure or manufacturing difficulties.
