Abstract: A thin spindle motor having a stator core with sufficient swaging strength even using thin magnetic steel sheets is provided, whereby the magnetic loss and the power consumption of the spindle motor are reduced. The stator core is formed by laminating plural stator laminations with a thickness of 0.1 to 0.2 mm and joined by a swaging portion. The swaging portion has an approximately rectangular shape having long sides extending along a radial direction when viewed from an axial direction. The swaging portion has a cross section with a middle portion parallel to the radial direction and a slope portion at the both sides when viewed from a circumferential direction, thereby forming a recess. The recess has a depth that is less than the thickness of the stator lamination whereby the swaging portion does not cut the stator lamination.

Abstract: A method for manufacturing a magnet-conductive device includes performing a punch process to a plate by a glue-injectable punch structure, wherein the glue-injectable punch structure includes a punch head and a control member. The punch head comprises an accommodating cavity, an injection hole and an inlet, and a supply channel is formed by the accommodating cavity, the injection hole and the inlet. The control member selectively obstructs the supply channel or permits the supply channel into conduction. By using the method for manufacturing the magnet-conductive device, the stack between plural plates is simplified, and the coupling strength between adjacent plates is enhanced. In addition, this invention considers the gel between adjacent plates to be insulating medium to lower the iron loss of the magnet-conductive plates.

Abstract: Stator core of motor stator is equipped with a segmented core connecting body which connects in an annular shape a segmented core having a structure whereby laminated core plates are connected and held in place in a laminated state. To connect and fix core laminated plates by clamping, first and second dowels formed in each core laminated plate are used to connect and fix common rings by pressure-fitting them to the first and second end faces at either side of the segmented core connecting body, thus integrating the segmented core connecting body. The segmented core connecting body can be integrated with a simple operation, thus significantly reducing the assembly time for the stator core.
