    Abstract: A disc machine has a stator from which teeth and a central boss project axially in the same direction with the central boss projecting beyond the teeth. An AC winding is wound through the slots between the teeth while a DC winding surrounds the central boss. A bar-like rotor has a central aperture and is mounted for rotation so that the boss passes through the central aperture with an axial gap between the rotor and the teeth.

    Abstract: Armature reaction in a dynamo is reduced by constructing the main pole structure and/or the commutating pole structure with a plurality of iron lamina arranged parallel to the axis of rotation of the dynamo. The iron lamina are separated from each other by nonmagnetic or magnetically weak material of a predetermined thickness designed to cause a predetermined minimum but high reluctance to be offered to flux generated in the main or commutating pole structure as a result of armature current. The core of each pole may be split into a first and second core half at the root and in the direction of the axis of rotation. Each core half has a larger portion which extends to the adjacent core half of the neighboring pole, thereby forming a yoke. A smaller portion of each core half extends into the air gap between poles and, together with the corresponding portion of the core half of the neighboring pole which is similarly extended into the same air gap, forms a commutating pole. Each iron lamina may be constructed of a plurality of sublaminas which are glued together.

    Abstract: A polyphase AC generator of a type designed for installation in automobiles, has a so-called Lundell type rotor in which an exciting coil is enclosed by a plurality of pairs of finger type magnetic poles and which is rotated by a vehicle-mounted engine. The shape of the finger magnetic poles is modified to an irregular trapezoidal shape having a side opposite to a base displaced with respect to said base in the direction of rotation of the rotor, thus changing the waveform of magnetic flux flowing through the rotor and an armature core and thereby reducing magnetic noise of the generator under load operation.

    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.

    Abstract: A sub-fractional electrical induction motor, particularly adapted to use in xerographic office copy machines and other applications involving the presence of quantities of nonexplosive magnetic powder; the portion of the magnetic stator frame encompassing the rotor is integrally molded into a plastic seal block, sealing all sides of an axial rotor opening except for two open ends. The rotor shaft is supported in bearing brackets that extend across the open ends of the rotor opening and that are tightly engaged with the seal block and sealed to the seal block by two gaskets, thus effectively encapsulating the rotor.
