    摘要： The problem of the present disclosure is to provide a method of manufacturing a rotor core by which a rotor core excellent in weight balance can be produced efficiently. A method of manufacturing a rotor core includes: acquiring weights of a plurality of permanent magnets individually; obtaining first to N th (N is a natural number equal to or greater than 2) magnet sets by combining at least one relatively heavy permanent magnet and at least one relatively light permanent magnet of the permanent magnets into one magnet set, based on the acquired individual weights of the permanent magnets; preparing a core body configured to rotate around a predetermined rotational axis, the core body having first to N th attaching locations in a row in a circumferential direction of the rotational axis; and attaching the first to N th magnet sets to any of the first to N th attaching locations one by one.

    摘要： A metal laminate includes a lamination of a first metal plate and a second metal plate. The first metal plate includes a caulking that exhibits a mountain shape protruding from a back surface side and recessed on a front surface side, and the second metal plate includes an accommodating portion configured to accommodate the caulking such that the caulking is fitted to the accommodating portion. The caulking includes a recessed portion provided on an inner concave surface of the caulking and recessed toward the back surface side of the first metal plate, and an abutting portion provided on an outer convex surface of the caulking and abutted against an inner surface of the accommodating portion at a position corresponding to the recessed portion. The abutting portion expands laterally from the outer convex surface toward the inner surface of the accommodating portion.

    摘要： An annular core piece in which an annular core piece can be received inside a contour of an outer circumstance of the annular core piece and the number of recesses formed on the outer circumstance is small is provided. In an annular core piece (1) including a plurality of recesses (5) opened in an outer circumferential part, the recess (5) includes a narrowed part (11) and a raised part (8), and a transverse width (W) of the narrowed part (11) is made narrower than a transverse width of a different region present on a side of a bottom of the recess (5) further beyond the narrowed part (11), and the raised part (8) is formed such that a part of the bottom of the recess (5) is raised and projected toward an opening end (6) of the recess (5).

    摘要： A method for manufacturing a rotor core includes detecting a height of a projecting portion formed on a lower die by a height detecting unit, and placing onto the lower die a core body in which a magnet insertion hole is formed such that the projecting portion is positioned in the magnet insertion hole when the height detecting unit has determined that the height of the projecting portion is within a set range. Additionally, the method includes bringing a permanent magnet in the magnet insertion hole into contact with an upper end of the projecting portion, and placing onto the core body a holding member after bringing the permanent magnet into contact with the upper end of the projecting portion. Melted resin is injected into the magnet insertion hole in which the permanent magnet has been inserted after placing the holding member onto the core body.

    摘要： A manufacturing method of a laminated core includes holding a laminated core body (2) mounted on a cull plate (1), injecting a resin to a magnet-insert hole from a resin reservoir part provided in a lower die through the cull plate (1), then ejecting the laminated core body (2) and the cull plate (1) and separating the cull plate (1) from the laminated core body (2). The cull plate (1) includes a through hole which forms at least a part of a flow path extended from the resin reservoir part to an upper surface of the cull plate (1). The through hole (4) of the cull plate (1) includes a tapered portion and a straight pipe portion being adjacent to the tapered portion. The tapered portion has an inner diameter gradually decreasing toward the upper surface of the cull plate (1), and the straight pipe portion has a constant inner diameter in a height direction.
