    摘要： A magnet insertion method into a rotor core is to insert an assembly into a magnet insertion hole provided in the rotor core of an electric motor, the assembly being formed by laminating a plurality of members, including at least a plurality of magnet pieces, in a line. According to this magnet insertion method, the assembly is formed by arranging a front member, having a surface surrounded by a chamfered ridge line, to cause the surface to be a front side end surface upon insertion, by laminating, on its rear side in an insertion direction, other members, without having the chamfered ridge line, in a line along the insertion direction to cause the other members to be hidden inside a projection of the front member when being projected from an insertion hole side, and by temporarily holding the front member and the other members.

    摘要： A manufacturing device for a field pole magnet body includes a reference jig having reference surfaces in the lengthwise direction, width direction, and thickness direction for positioning a plurality of cleaved and divided magnet fragments in an aligned state. The manufacturing device further includes a first pressing means that presses the plurality of magnet fragments to the thickness direction reference surface from the thickness direction of a magnet body to align them in the thickness direction, and a second pressing means that presses the plurality of magnet fragments to the width direction reference surface from the width direction of the magnet body to align them in the width direction. An operational axis line of a pressing part of at least one of the first and second pressing means is arranged to be tilted such that it approaches the lengthwise direction reference surface at the side that abuts the magnet fragments.

    摘要： The magnet cutting device includes a pair of supporting portions spaced apart by a predetermined distance and configured to support the magnet from a bottom side, a blade configured to press the magnet supported by the pair of supporting portions from an upper side of the magnet, and a magnet supporting tool arranged between the pair of supporting portions to support the magnet from the bottom side of the magnet. A surface of the magnet supporting tool to be held in contact with the magnet is shaped such that a central part of an upper end is higher than the upper ends of the pair of supporting portions and an end part of the upper end is lower than the upper ends of the pair of supporting portions when the magnet is placed on the surface, the upper end having a slope connecting the central part and the end part.

    摘要： An apparatus for manufacturing a field pole magnetic body formed by laminating magnet segments produced by cutting and dividing a permanent magnet and to be arranged in a rotary electric machine includes a housing part adapted to successively house a plurality of the magnet segments having adhesive applied to cut surfaces with the cut surfaces facing each other and has an inner side surface adjacent to outer side surfaces of the housed magnet segments, and a pressing unit adapted to press the magnet segments housed in the housing part toward a bottom part of the housing part in a longitudinal direction. The magnet segments are restrained in a width direction and a thickness direction by the inner side surface of the housing part when the magnet segments are pressed by the pressing unit.
