摘要： In a rotary electric machine laminated core, a rotating shaft portion is disposed closer to an outer circumferential surface than an inner circumferential surface of a back yoke portion. A notch portion is disposed on at least one of first and second end portions of the back yoke portion so as to form a gap between a vicinity of the rotating shaft portion of a projecting portion and a recess portion when core segments are arranged in an annular shape or a circular arc shape. The first end portion and the second end portion of the back yoke portion are configured such that a predetermined gap that connects from the outer circumferential side to the inner circumferential side is formed between adjacent projecting portions and recess portions when the core segments are expanded rectilinearly such that magnetic pole tooth portions are parallel to each other.

摘要： A wire-winding machine for forming coils (20) on individual magnetic pole teeth (11a) of a core member (13) which is produced by joining a plurality of core segments (11), each of the core segments (11) having a yoke portion (11c) and a magnetic pole tooth (11a) projectingly formed on an inside surface (11d) of the yoke portion (11c), comprises a core member positioner including a rotating roller (14), large-diameter guide rollers (21) and small-diameter guide rollers (22) which together serve to bend the core member (13) and hold it in a position where the core segments (11.3, 11.5) adjacent to the core segment (11.4) on which the coil (20) is currently wound do not project in the direction of its magnetic pole tooth (11a) beyond a boundary surface (S) of the yoke portion (11c) of the core segment (11.4) on which the coil (20) is currently wound.

摘要： A core has a plurality of plate-shape core pieces with a magnetic pole tooth and having connecting portions formed at one end and having a first circular arc end surface and having at the other end a second end surface which can mate with the first end surface of an adjoining core piece. The core pieces are arranged in the shape of a strip through the end surfaces to form a first core member and a second core member. The core members are stacked so that the ends of adjoining core pieces in the stacking direction overlap and such that adjoining connecting portions can freely rotate through connecting means to form a ring with the magnetic pole teeth on the inside. A cutout is formed in the corner of the outer side of the core in the second end surface of each core piece.

摘要： The magnetic performance, rigidity and mechanical precision of an iron core assembly can be improved. A plurality of plate-shaped core segments are disposed in succession to form a plurality of first and second core members respectively. Edge portions of adjacent core segments of the first and second core members are coupled with each other. The first and second core members are alternately laminated one over another in such a manner that first inter-segment positions each defined between adjacent two first core segments of the first core member are offset from second inter-segment positions each defined between adjacent two second core segments of the second core member in a longitudinal direction of the first and second core members, with those edge portions of the respective first and second core segments which adjoin each other in a laminating direction in which the first and second core members are laminated being overlapped each other. The core segments of the first and second core members are rotated relative to each other through the coupling means so as to form an enclosed or ring-like configuration.

摘要： An armature of a linear motor includes a plurality of first magnetic teeth and a plurality of second magnetic teeth, each of the magnetic teeth being formed by laminating multiple tooth elements made of electromagnetic steel sheets. The first magnetic teeth are arranged side by side in a linear form while the second magnetic teeth are located one each between the successive first magnetic teeth. Each of the second magnetic teeth interconnects the two adjacent first magnetic teeth located on both sides.

摘要： A linear motor comprises a stator including a stator yoke and a plurality of permanent magnets arranged side by side on the stator yoke along a motor running direction in alternately reversed directions to produce alternating polarities, and a moving part including a plurality of magnetic teeth arranged along the motor running direction and coils wound around the individual magnetic teeth. Cutouts formed in end surfaces of yoke portions of the individual magnetic teeth opposite to their side facing the stator line up to form a groove-shaped channel running through the yoke portions of the successive magnetic teeth, and the multiple magnetic teeth are joined together into a single structure by fitting a connecting bar in the groove-shaped channel.
