摘要： Respective divided segments of a collet are moved radially outward by moving an arbor axially. The respective divided segments thereby press an inner circumferential surface of a stator core of a stator from radially inside such that the stator is held coaxially by the collet. Next, shaping rollers are lowered so as to press an outer circumferential surface of the stator core. The stator is rotated by rotating the collet in that state. Thus, the inner circumferential surface of the stator core is compressed and plastically deformed so as to conform to the collet and the outer circumferential surface of the stator core is compressed and plastically deformed by the shaping rollers, correcting the inner circumferential surface and the outer circumferential surface of the stator core so as to be coaxial and so as to have a high degree of roundness.

摘要： The present invention provides a dynamoelectric machine that suppresses the occurrence of insulation failure that accompanies oxidation of a stator core without lowering output, and that also suppresses stator temperature increases by transferring heat that is generated in a stator coil efficiently to a frame.A stator core is configured by laminating and integrating thin magnetic plates, and has an outer circumferential surface that has a cylindrical surface, and receiving grooves are formed on inner circumferences of openings of frames. The receiving grooves are constituted by: an annular axial surface that is constituted by a flat surface that is perpendicular to a central axis of the stator core; and a radial surface that is constituted by a cylindrical surface that is centered around the central axis. Metal surfaces of the thin magnetic plates at two axial ends of the stator core are held between each of the axial surfaces of the pair of frames in a state of close contact around an entire circumference.

摘要： A permanent magnet rotor includes: a rotor core of a laminated structure about a rotation shaft; a plurality of permanent magnet embedment slots provided to the rotor core at equally spaced positions from the rotation shaft; and permanent magnets inserted into the respective permanent magnet embedment slots. The permanent magnet embedment slots each have a magnet storing portion and a buffer and other members storing portion continuing to the magnet storing portion. One permanent magnet is stored in the magnet storing portion and a buffer member and a pushing member used to fix the permanent magnet are stored in the buffer and other members storing portion. It thus becomes possible to provide a permanent magnet rotor capable of not only preventing damage on a permanent magnet by reducing resonance even when the magnet resonates under a vibration condition, but also enhancing mass-productivity.
