Abstract: A method for manufacturing a rotor includes, with a magnet accommodated in a magnet housing hole of a rotor core, causing a first die to contact a first end face of the rotor core and causing a second die to contact a second end face of the rotor core. The method also includes injecting the thermoplastic into the magnet housing hole through a passage of the second die in a state in which the first die and the second die are respectively in contact with the first end face and the second end face and the first die is heated.

Abstract: Forming a caulking portion involves forming: a planar portion that is connected to a main body of an iron core piece, that is formed into a concave shape with respect to a face of the iron core piece which is on one side in the thickness direction, that formed into a convex shape with respect to a face of the iron core piece which is on another side in the thickness direction, and that is parallel to the faces; and a pair of extended portions that include a pair of sloped portions which extend out obliquely from both ends, along the lengthwise direction of the caulking portion, of the planar portion, toward mutually opposite sides in the lengthwise direction and toward another side in the thickness direction. Forming the pair of sloped portions involves extending the pair of sloped portions in the oblique directions.

Abstract: A rotor core includes first and second laminate steel plates extending in a radial direction with respect to a central axis. The first laminate steel plate includes a first base portion positioned on a radially outer side of the central axis, and pieces separately positioned on a radially outer side of the first base portion with penetrating portions therebetween, and disposed at predetermined intervals in a circumferential direction. The second laminated steel sheet includes a second base portion positioned on a radially outer side of the central axis, and annular portions separately disposed on a radially outer side of the second base portion with penetrating portions therebetween, and extending in a circumferential direction. The rotor core is defined by the first laminate steel plates and at least one of the second laminate steel plates laminated in an axial direction.

CPC classification number: H02K15/02 , H02K2201/09
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: This disclosure relates to a method of manufacturing a laminated core. The manufacturing method includes the steps of feeding a belt-like core material to a progressive die, stamping out core pieces having a first shape from the core material, stacking more than one of the core pieces having the first shape to obtain a first laminate block, stamping out core pieces having a second shape from the core material, stacking more than one of the core pieces having the second shape to obtain a second laminate block, discharging a laminate including the first laminate block and the second laminate block from the progressive die, changing the lamination order of the laminate blocks constituting the laminate, and integrating the laminate after the lamination order of the laminate blocks are changed.
