Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

Abstract: A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.

Abstract: 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.

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.
