Abstract: An iron core for a rotary electric machine suitable for use as stator iron cores of AC generators for vehicles, for example, winding an iron core blank of strip form and joining convolutions of the spirally wound iron core blank together by electric resistance winding. The spirally wound iron core blank has a plurality of circumferentially spaced apart projections on one surface and a plurality of circumferentially spaced apart recesses on the other surface in positions corresponding to the projections on the one surface. The projections and recesses coincide in position when the iron core blank is spirally wound and convolutions thereof are superposed one above another. The provision of the projections and recesses enables winding of the iron core blank into a spiral form and welding of the convolutions of the spirally wound iron core blank to be effected economically and with increased accuracy.

Abstract: A die structure for use in a laminated core manufacture wherein a plurality of apertured sheets 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 sheets is provided with a through aperture with the projection being eliminated so as to define a nonprojecting surface in the first of the sheets of the stack, with the projections of each of the subsequent sheets extending into and being interlocked with the preceding sheets 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 sheets of the stack. The extent of the projections from the sheets is preselected to be no greater than the thickness of the sheets so that the projection of the sheets superjacent the first lamination is received fully within the blanked out aperture thereof. The blanked out sheets may be indexed to define a skewed axis dynamoelectric structure.

Abstract: An electric motor of a construction, wherein conductive wires are wound around the outer periphery of an armature core substantially in parallel with a rotor shaft and in such a manner that the terminal connection part of the winding may be provided in the axial direction of the rotor shaft, and, at the same time, a commutator is disposed inwardly at a position nearer to the core than the projected end of the terminal connection part of the winding which projects outwardly in the same direction as the axial direction of the core, whereby the length of the rotary armature in the axial direction thereof is shortened to flatten the motor per se in the axial direction thereof.
