    Abstract: The present invention involves a method and apparatus for forming a centrally interlocked stack of laminations for rotors. A centrally located, circular indentation is formed in each lamination. The indentation provides corresponding projections and depressions in the laminas which may be interlocked by engaging adjacent depressions and projections. Using a progressive die assembly, laminas are blanked from stock sheet material and punched to form the projection/depression. The machine for manufacturing the laminations includes a blanking station including a punch for forming the projections/depressions, and a rotating and stacking station. The projection/depression forming station includes a counterforce which is applied when punching the projection/depression so that the stock material is relatively flat. The laminations are blanked, then rotated, and finally stacked together to form a lamination stack.

    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: An electromagnetic drive apparatus comprises a stator yoke excited with supply of power to a coil, a rotor arranged as capable of being driven by excitation of the stator yoke so as to move a driven member, and a fixed member for positioning and supporting the rotor and the stator yoke. The stator yoke has a projecting portion or a recessed portion and the stator yoke is positioned and supported relative to the fixed member by the projecting portion or the recessed portion to provide a compact motor without causing a drop of efficiency in the power of the motor.

    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 permanent magnet alternator includes a stator core having outwardly projecting teeth and further includes a plurality of permanent magnets surrounding the stator core. The stator core is formed from a continuous, helically wound metallic strip having a plurality of teeth defined between slots formed in one edge thereof. The stator core is formed by winding the strip edgewise around a cylindrical mandrel. To facilitate winding and avoid distortion, arcuate regions, conforming to the curve of the mandrel, are formed in the strip opposite the teeth.

    Abstract: A dynamoelectric machine core, method of forming the same, and apparatus for forming the same. The core includes a stacked laminated yoke assembly having an annular array of radially inwardly opening recesses, a stacked laminated tooth assembly having an annular array of annularly spaced teeth defining therebetween winding slots, a dynamoelectric winding in the slots, and cooperating interlock means on the teeth and yoke core assemblies for locking the tooth core assembly to the yoke core assembly. The laminations are blanked out from a metal sheet and interlocked in stacked association with each other by suitable interlock structure formed therein. The teeth are blanked out from the yoke lamination and are subsequently secured to the yoke laminations of the yoke core assembly after the tooth core assembly of the teeth is provided with the dynamoelectric winding. The teeth may be held by a suitable jig during the winding operation which accurately disposes the teeth to define the tooth core assembly and which is removed subsequent to the mounting of the wound tooth core assembly to the yoke core.

    Abstract: A laminated core manufacture wherein a plurality of apertured laminations are provided with projections formed from the portion of the sheet from which the apertures are formed to define an interlocked laminated stack. The first of the laminations is provided with a through aperture with the projection being eliminated so as to define a nonprojecting surface in the first of the laminations of the stack, with the projections of each of the subsequent laminations extending into and being interlocked with the preceding lamination in the aperture thereof. The punching apparatus for providing the apertures and projections is selectively operated to define either the formed aperture and projection structure or a blanked out apertured structure. The blanked out apertured structure defines the first of the laminations of the stack. The extent of the projections from the laminations is preselected to be no greater than the thickness of the laminations so that the projection of the laminations superjacent the first lamination is received fully within the blanked out aperture thereof. The blanked out laminations may be indexed to define a skewed axis dynamoelectric structure.
