摘要： 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.

摘要： A resolver is installed inside a housing of a motor. A stator of the resolver has a three layered core. a main layer of an electric steel sheet, a first shielding layer of a magnetic metal, a second shielding layer interposed between the domain layer and the first to shielding layer. The second shielding layer is made of a non-magnetic material.

摘要： A stator support member of a rotating electrical machine is provided with a cooling channel formed in the stator support member to cool a stator. The stator support member is manufactured to have the cooling channel of a hermetically sealed structure so that a cooling fluid may flow along the cooling channel. In particular, the support member having the cooling channel is divided into a ring-shaped outer part and a ring-shaped inner part (two-piece type) and the separately manufactured ring-shaped outer part and inner part are combined together.
