    Abstract: A method of manufacture for a stator core including the steps of a) punching a stacked plurality of long bands of sheet steel to form strip laminations having tooth portions and core back portions; and b) spirally winding the strip laminations and integrating the wound strip laminations. The stacked plurality of long bands of sheet steel can be punched over their width such that at least one pair of the strip laminations is formed and two of the strip laminations form a pair by intermeshing the protrusions and recesses of their respective tooth portions.

    Abstract: A method of producing a laminated iron core by punching and laminating rotor and stator core pieces. The rotor core pieces are punched from a metal sheet and laminated. Magnetic pole teeth are roughly punched in the metal sheet with the rotor core pieces removed. Each of a plurality of magnetic pole teeth are pressed at plural different portions to form thin parts so as to develop the plurality of magnetic pole teeth toward the punched side of the rotor core piece. Thereafter, the stator core piece is punched to form front tips on the magnetic pole teeth defining an internal form on the stator core piece. An external form of the stator core piece is punched. The punched stator core pieces are laminated in succession.

    Abstract: A laminated plate assembly in which the laminations in a stack are secured together by means of one or more interlocks or tabs that project from the uppermost lamination in the assembly through holes or slots in all the other laminations in the assembly, or around the periphery of the other laminations in the assembly, with each tab being bent or pressed against the underside of the bottom lamination in the assembly. This secures all the laminations in the stack together, much like a staple secures papers in a stack together, allowing for additional handling and processing of the laminated plate assembly without concern that the laminated plates in the stack will become misaligned or even become removed from the stack.

    Abstract: In a method of producing an iron core by punching and laminating stator core pieces and rotor core pieces from the same metal sheet, it is an object of the invention that magnetic pole teeth of the roughly punched stator core pieces are caused to stably develop by pressing toward space sides made by previously punching the rotor core pieces so as to sufficiently secure punching margins for pressing out the front tips of the magnetic pole teeth of the internal forms of the stator core pieces and the punching can be performed without obstacles even if a gap with the rotor core pieces is small, and further ruggedness formed on a surface of the metal sheet by pressing does not cause disturbances in a flow of magnetic flux. The method comprises punching the rotor core pieces from metal sheets and laminating them, roughly punching the magnetic pole teeth 7 of the stator core pieces from said metal sheets already punched of the rotor pieces, changing positions of the magnetic pole teeth 7, pressing on a plurality of parts thereof to reduce the thickness, developing them toward the punched sides of the rotor core pieces for forming the thin part ranges 10, 11, subsequently punching to form the front tips 8 of the magnetic pole teeth composing edge parts of the internal forms of the stator core pieces, punching the external forms of the stator core pieces and laminating them.

    Abstract: 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.
