    Abstract: The stator of a built-in motor must be firmly and accurately mounted on the spindle head housing or the like of a machine tool. A stator core (10), i.e., a principal component of the stator is welded partially at the circumference (14) thereof, and then the circumference of the stator core (10) held by a mandrel is finished to an accurate outside diameter by grinding. The stator core (10) thus constructed is subjected to a deformation with a lapse of time after the mandrel has been removed. To solve this problem, each lamination (12) of the stator core (10) is coated with a thermosetting adhesive, to be thereby joined together, and each lamination (12) is provided with a plurality of pressed projections (22) to be joined together by weld portions (20) on the circumference of the stator core (10), or each lamination (12) is joined together by pressing a serrated bar (26) into a bore (24) thereof, without a pressed projection (22).

    Abstract: A stepper motor housing an pole structure is disclosed in which a pair of identical stator plates, each having a plurality of poles, are positioned back to back with the poles projecting in opposite directions, the stator plates being positioned between a pair of substantially identical stator cups, each stator cup having a plurality of poles projecting inwardly from a back wall with a peripheral side wall terminating in an outwardly extending flange. A major surface of each flange is in contact with a face on one of the stator plates so as to assure a low reluctance magnetic path.

    Abstract: A method for the manufacture of plate-packs of coated metal laminas for electrical machinery and appliances in which the number of necessary manufacturing steps is reduced. After the laminas have been punched or stamped out, they are electrically upgraded by annealing and in the process are arranged at intervals with respect to one another and exposed to a reducing gaseous atmosphere. Then projections or depressions, known from punch-packing processes, which correspond to each other are punched into the laminas to connect them together. The laminas of a plate-pack are assembled into a unit by means of the interlocking projections and depressions prior to the annealing by an initial axial pressing step with an ensured axial minimum separation. After the annealing treatment, by means of a final axial pressing step, they are assembled into the final plate-pack form. The resulting plate-packs are particularly well suited for laminated stator or rotor packs for small electric motors or for electromagnetic switch gear.

    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: The present disclosure relates to a manufacturing method for a laminated core, which manufactures the laminated core by bonding lamina members. The manufacturing method includes: a laminated core forming step of forming a laminated core by sequentially forming and laminating lamina members having a predetermined shape while passing a thin sheet having an adhesive layer formed on a surface thereof; a magnet insertion step of inserting a magnet into a magnet insertion hole of the laminated core; a resin filling step of filling resin in the magnet insertion hole of the laminated core into which the magnet is inserted; and a curing step of heating the resin-filled laminated core to cure the adhesive layer of the lamina member, so that the laminated core is integrated and the filled resin is simultaneously cured.
