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.

Abstract: A laminated stack having a lamina layer comprised of a plurality of discrete lamina segments and which may also have laminas which define a plurality of outer perimeter configurations. The invention provides a method and apparatus for manufacturing such stacks. Lamina layers comprising a plurality of discrete lamina segments are automatically stacked by positioning the uppermost lamina in a choke barrel near the lower die bed surface and engaging the interlock tabs of the discrete lamina segments with the interlock slots of an uppermost lamina layer in the choke barrel prior to the complete separation of the discrete lamina segments from the remaining portion of the strip stock material. Each of the outer perimeter configurations has at least one common choke surface. The common choke surfaces form, when the laminas are stacked, a choke contacting surface on the outer perimeter surface of the lamina stack which extends continuously in the axial direction from the top lamina to the bottom lamina A die assembly having selectively actuated punches is used to stamp the laminas with a plurality of outer perimeter configurations and the laminas are stacked in a choke barrel with an alignment surface which cooperates with the common choke surface and securely holds the stamped laminas in position while the stack is being formed. Rotation of the choke barrel compensates for strip thickness variations.

Abstract: Elongated thin strip stock is blanked to form interlocking laminas for electric motor or generator rotors or stators at successive blanking stations. At a final assembly station the laminas are stacked and pressed into interlocking relationship. In response to an operator input a predetermined number of reversals, or half turns about the stack axis of the previously stacked lamina are provided in order to compensate for nonuniform strip thickness to obtain a rotor or stator of substantially uniform height. Alternatively the thickness of the strip stock is gauged at transversely spaced points on the strip to determine cross feed thickness variation in the strip whereupon the stacked laminas are automatically provided with a number of reversals about the stack axis in response to a thickness differential that would result in a parallelism error in the stack that exceeds a predetermined amount. Rotor conductor slots are formed in the stacked laminas and are skewed to the stack axis by providing arcuate indexing of each lamina relative to the next preceding lamina in the stack by an arcuate increment that is automatically determined in response to operator entered inputs relative to the stack height, the skew angle, nominal lamina thickness and skew direction.

Abstract: A motor rotor or stator core is formed of a plurality of stacked generally circular laminations. The stack defines at least one inner lamination having laminations positioned adjacent to both sides of the lamination. Each lamination has a predetermined number of circumferentially equally spaced slots or bar elements extending radially at about an edge thereof. The inner laminations include at least one interlocking projection formed in one of the surfaces at a predetermined radial distance from the center of the lamination. The laminations further define at least one projection receiving region formed therein to engage the projection when the laminations arc in the stacked formation. The projection receiving region is spaced from the interlocking projection by an angle .phi. that is a whole number multiple of .beta., where .beta. is an angle defined as a ratio of 360 degrees to the number of slots. A method for making the stacked core is also disclosed.
