Abstract: A stator assembly includes a stator core including teeth, which are formed along an inner circumferential surface of the stator core, extend from one surface of the stator core to an opposite surface of the stator core, and have through holes formed through one surfaces of the teeth, respectively, a plurality of hairpins, each hairpin coupled to and connected with a slot formed between the teeth facing each other and forming form a coil winding, and a heat radiating device including a first heat radiating member provided at one side of the one surface of the stator core to discharge heat of the hairpin to an outside, such that the hairpin is cooled.

Abstract: A grommet includes a body, which has a block shape with a wire passing hole formed by perforation, and a guide, which extends from one end of the body at a predetermined angle and has a guide hole formed by perforation.

Abstract: The present invention relates to an improved structure of a core-bobbin assembly without using a support ring, an O-ring, and a gasket which support and cool the core-bobbin assembly of a motor for a vehicle, so that a weight decreases, and a heat transfer area increases. The present invention also relates to a motor cooling method using the same. In the present invention, an outer circumference sheath (210) is added to a bobbin to cover an entirety of a core outer circumferential portion (110) including a cooling surface press-inserted into and in contact with a housing, that is, a recessed outer circumferential surface (120) formed on the core outer circumferential portion (110).

Abstract: A block terminal including a plurality of bus bars including ring-shaped connection terminals at both ends thereof; a block base formed to surround bodies of the plurality of bus bars excluding the connection terminals and provided with a slit passing through a surface thereof; and a housing cover formed to surround a surface of the block base and detachably attached to the block base.

Abstract: Provided are a one body type terminal assembly of a driving motor for a vehicle and a manufacturing method thereof, the one body type terminal assembly including a bus bar assembly including a plurality of ring-shaped bus bars overlapping each other, each of which is primarily insert-injection-molded and of which an outer surface is surrounded with an insulating material; and flanges which are simultaneously insert-injection-molded with the bus bar assembly to be formed to protrude from an outer circumferential surface of the bus bar assembly at intervals when the bus bar assembly is secondarily insert-injection-molded.

Abstract: A structure for assembling a temperature sensor of an annular terminal unit for a drive motor. The structure includes a terminal holder having an annular shape, a temperature sensor fixed to the terminal holder, a plurality of cores radially arranged on a lower surface of the terminal holder, a bobbin inserted into each of the plurality of cores, and a stator coil wound around each of the bobbins. The temperature sensor passes through the terminal holder in a vertical direction of the terminal holder and is inserted between the bobbins around which the stator coils are wound.
