Abstract
A direct-cooling stator core assembly having cooling channels so as to directly cool a stator core and a wound coil, and a driving motor for a vehicle including the same, are provided. The direct-cooling stator core assembly includes a stator core having an outer surface and a plurality of core recesses formed in the outer surface in a longitudinal direction. The direct-cooling stator core assembly further includes a cooling fluid supply member configured to supply cooling fluid to the core recesses in the stator core. In the direct-cooling stator core assembly, when cooling fluid is flowing through the core recesses, the cooling fluid flowing through the core recesses directly cools the stator core.
