摘要： A rotor for an asynchronous machine has a laminated core and a short-circuit cage at least partially integrated in the laminated core. The short-circuit cage is designed with rods having or consisting of a first electrically conductive material and short-circuit rings having or consisting of a second electrically conductive material. At least one of the short-circuit rings is designed with a support ring, and each support ring is designed as a structure interlockingly and/or integrally cast onto or into the associated short-circuit ring.

摘要： A method is provided for fabricating a rotor assembly for an electric motor which utilizes pre-fabricated conductive rotor bars and die cast end rings. Containment rings, which may be installed on the end rings either before or after casting, may be used to inhibit end ring creep at high rotational speeds.

摘要： A method includes steps of: preparing first and second plates, each first plate having surrounding apertures, each aperture including a first accommodation portion and an outer necking portion, each second plate having surrounding accommodation portions; stacking the first plates by aligning necking portions to form band gaps extending linearly and parallel to each other; stacking two second plates to two opposing terminal portions of the stacked first plates; penetrating metal bars into the aligned first and second accommodation portions by exposing both ends of each metal bar; beetling the necking portions at each band gap so as to locate firmly the corresponding metal bar; positioning a first mold and a second mold to clamp the stacked plate structure; injecting metal slurries into the first and second molds and then solidifying the metal slurries to form two end rings; and, removing the first and second molds to complete a rotor structure.

摘要： A rotor assembly is provided in which a solid rotor ring is formed at either end of a stack of laminated discs, the solid rotor rings yielding improved electrical and mechanical characteristics in a low weight assembly. The solid rotor rings are fabricated by brazing slugs between the end portions of the rotor bars, the braze joints contacting a large percentage (at least 90%) of the rotor bar end portions.

摘要： A lamination pack for a motor and method of forming the lamination pack is provided. The method includes inserting a plurality of conductor bars into a plurality of rotor slots defined by a lamination stack such that opposing bar ends of the conductor bars extend from opposing end faces of the lamination stack, skewing the lamination stack and the conductor bars to a skew angle relative to a rotation axis of the lamination stack, and subsequently bending the bar ends of the conductor bars in opposing radial directions to a locking angle greater than the skew angle, to lock each of the conductor bars in its respective rotor slot. The bent bar ends exert a compressive axial locking force on the lamination stack to prevent axial and radial movement of the laminations in the lamination stack and to prevent axial movement of the conductor bars relative to the lamination stack.

摘要： This squirrel-cage motor rotor includes a plurality of conductor bars provided at regular intervals along the circumferential direction of a rotor core, short-circuit rings connected to ends of the conductor bars, and reinforcement covers having axial-direction surfaces being in contact with axial-direction-end surfaces of the short-circuit rings. The reinforcement covers are enclosed by casting in the short-circuit rings. Holding rings are attached to the outer circumferential surfaces of the flange portions of the reinforcement covers and the outer circumferential surfaces of the short-circuit rings by interference fit.

摘要： A rotor core includes a rotor core includes a plurality of rotor core blocks each of which is constituted by stacking annular sheet-like core materials in a direction of sheet thickness of each core material and a plurality of catch recesses circumferentially disposed in an inner circumference of each core material at an interval of a predetermined angle so as to extend radially outward, the catch recesses having respective circumferential dimensions equal to each other and different radial depths. In each rotor core block, a plurality of the core materials is stacked while the catch recesses having an identical configuration are aligned. The rotor core blocks have respective outer peripheries which are shifted from each other according to the depths of the catch recesses caught by a bar-shaped aligning jig when the catch recesses of the rotor core blocks are caught by the aligning jig.
