Abstract: A rotary electric machine includes a rotor, a stator having coils wound to surround the rotor, a cylindrical ring member fixedly mounted on the stator by shrinkage fitting, and a frame disposed on the outside of the ring member with a gap created in between. The distance of the gap varies as a result of thermal expansion of the stator and the ring member. An outer surface of the ring member goes into contact with the frame when the stator and the ring member thermally expand, whereby the stator and the ring member are efficiently cooled.

Abstract: A rotary electric machine includes a stator in which a plurality of armatures each have a coil formed by a winding wire wound in plural layers around bobbins mounted to a magnetic pole tooth, which are disposed annularly on an inner circumference of a cylindrical frame. The coil is formed by the winding wire being wound with a constant feed pitch in parallel with slots of the bobbins in plural layers. The winding wire forming a first layer of the coil is shifted by half the feed pitch between a left side and a right side of a center axis of the coil as viewed from a plane perpendicular to a stacking direction of a stacked iron core.

Abstract: An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by ensuring outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on portions of yoke portions between respective circumferentially adjacent claw-shaped magnetic pole portions. Magnet holders are disposed so as to span over all of the trough portions on a pole core body at a rear end excluding a predetermined trough portion, and permanent magnets are held in each of the magnet holders. A field coil lead wire is led out from the rotor so as to pass through the trough portion over which a magnet holder is not disposed.

Abstract: 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.
