徴とするものである。2) Means for Solving the Problems The basic structure of the present invention is a rotor core in which stamped rotor cores are laminated and formed by aluminum die-casting.
A plurality of slots are arranged in an annular manner on the outer periphery of the rotor core, and an appropriate number of relief holes for skewing are bored near the inner side of the slots, and a number of relief holes for skewing are formed in communication with the core relief holes for caulking and lamination. It is characterized in that the projections are provided in the same circumferential direction, and the skew removal hole and the slot are communicated with each other through a slit.

以下本発明を第４図乃至第６図に示す実施例に基づいて
説明する。With this configuration, when the rotor cores are laminated by laminating the rotor cores by overlapping the protrusions for caulking and lamination, the position of the rotor cores can be shifted in the circumferential direction each time the rotor cores are stacked using the relief holes for deskewing, and the skew can be taken out at the same time as the lamination is laminated by caulking. Since the escape hole for removing the skew is communicated with the slot through the slit, the crimping of the protrusion for laminating the crimping force does not escape into the slot, improving the crimping strength. Embodiment The present invention will be explained based on the embodiment shown in FIGS. 4 to 6. The height of the end ring is reduced by filling the escape hole for removing the skew with aluminum.

リングの高さを低くできる箸実用的な効果を有する。(f) Effects As described above, the present invention provides a rotor core in which stamped rotor cores are laminated and aluminum tie-cast molded. An appropriate number of relief holes for removing the skew are bored in the hole, protrusions for caulking and lamination are provided in the same circumferential direction in communication with the relief holes, and the relief holes for removing the skew and the slot are connected by slits. Therefore, when the protrusions for caulking and lamination are superimposed and the rotor cores are laminated by caulking, the escape hole for removing the skew is communicated with the slot through the slit, so that the caulking mechanism of the protrusions is The chopsticks have a practical effect in that the crimping strength is improved without escaping into the slot, and the escape hole for releasing the skew is filled with aluminum through the slit during aluminum die casting, allowing the height of the end ring to be lowered.
