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: A magnet is provided on the inner circumferential surface of a hub rotatable about a central axis C of the motor, and a stator is arranged inside the inner circumferential surface of the hub to oppose the magnet. The stator core of the stator is formed by stacking substantially annular, plate-shaped core forming members, and has an annular portion arranged to be coaxial with the central axis, a plurality of winding portions projecting from the annular portion radially, and pole portions formed on the extending ends of the respective winding portions and opposing the magnet. Each winding portion is squeezed in the stacking direction by plastic formation such that its thickness is smaller than those of the annular portion and pole portion. A coil is wound on each squeezed winding portion.

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: An apparatus for forming a stack of interlocked laminations (disks) that can be used as a rotor in an electric motor. Each disk is severed from a metal sheet that is passed horizontally through a die apparatus. The severed disks are sequentially driven downwardly into a vertical die opening having an upper diameter chosen to grip the disk edges, as a stack is being formed. The lower end of the stack advances into an expandable rotatable collet. When the stack has passed below the upper end of the die opening, the collet is opened to drop the completed stack to a conveyor.A sensor device detects the lowest disk in the descending stack. A signal generated by the sensor device is used to determine the number of disks necessary to finish the stack by dividing the unfinished height of the stack by the thickness of the advancing metal sheet.
