    Abstract: A method of retaining a series of plates together in a stacked relationship, using integral projections and mating recesses formed by punching dies. As each plate is added to the stack, a restriking die is driven against the exposed face of the newly added plate to form transverse notches in the plate surface. The plate is thus deformed so that material flows into previously formed notches in a subjacent plate. The displaced material acts as a frictional interlock with the subjacent plate.

    Abstract: There is disclosed a metal plate laminated body. When a portion encircled by inner and outer closed curves is embossed, a projection is protruded from a lower surface of a metal plate. Since a width of protrusion is slightly larger than that of a recess, when press-fitting the projection into the recess of the contiguous metal plate, an outer peripheral surface of the projection which is formed along the outer closed curve is brought into press-contact with an outer peripheral surface of the recess; and an inner peripheral surface of the projection which is formed along the inner closed curve similarly comes in press-contact with an inner peripheral surface of the recess. These inner and outer peripheral surfaces cooperate to become effective contactual surfaces, and the contiguous metal plates are joined to each other.

    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 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.
