Abstract

PURPOSE: To make a rotor thinner and the motor smaller by preparing projections available for caulking and laminating through some slender slots which are contained in rotor core slots.
CONSTITUTION: Some slots 16 among the slots 3 equipped circumferentially of a rotor core 2 have a slender form. At the end of the internal circumference of these slots 16 projection parts 4 for caulking are given circumferentially as relief parts. A laminated iron core is formed by laminating and caulking projections 4 one over another as relief parts of the slots 16 for skewing. When monobloc casting is carried out by aluminium to the iron cores 6 and end rings 7, 8, the end rings 7, 8 can decrease their thickness as they are disturbed by the relief parts. The whole rotor can be made thinner and the motor becomes smaller.
