摘要： A stator for an electric rotating machine is equipped with a stator winding made up of a plurality of conductor segments. Each of the conductor segments has a head and two legs. The legs are inserted through their respective slots formed in a stator core, so that each of the conductor segments has leg ends protruding from either one of opposed end surfaces of the stator core and the head thereof protruding from the other end surface. Radially adjacent two of the leg ends are provided as a coil end pair to be welded. At least one of the heads is interposed between adjacent two of the coil end pairs, thereby ensuring a distance between the two adjacent coil end pairs which is great enough to provide a required degree of electric insulation between the coil end pairs when the leg ends of the conductor segments are welded electrically.

摘要： A stator includes an annular stator core and a stator coil. In each of slots of the stator core, there are received a predetermined number of in-slot portions of the stator coil in alignment with each other in a radial direction of the stator core. Each of side surfaces of tooth portions of the stator core includes, at its radially inner end, an oblique surface that extends obliquely with respect to the radial direction. The oblique surfaces are shaped so that for each of the slots, the circumferential width of the slot is decreased in the radially inward direction in that part of the slot which is located between a corresponding pair of the oblique surfaces. For each of the slots, the in-slot portion which is located radially innermost in the slot is held at a predetermined radial position by the corresponding pair of the oblique surfaces.

摘要： A rotor for an electric rotating machine includes a rotor core and a plurality of magnetic poles. The rotor core is formed of a plurality of magnetic steel sheets laminated in the axial direction of the rotor core. The magnetic poles are formed on a radially outer periphery of the rotor core. The magnetic poles are arranged at predetermined intervals in the circumferential direction of the rotor core so that the polarities of the magnetic poles alternate between north and south in the circumferential direction. Furthermore, the magnetic steel sheets forming the rotor core are welded so that a plurality of welds are formed on one of radially outer and inner surfaces of the rotor core. Each of the welds has a pair of axial end portions that are offset from each other in the circumferential direction of the rotor core and electrically connected to each other.

摘要： A rotor includes a rotor core with a circumferential surface facing a stator and permanent magnets each received in a corresponding slot of the rotor core. Each of the permanent magnets has a first corner portion positioned closest to the circumferential surface of the rotor core and a first side surface that intersects an imaginary line, faces toward the stator side and makes up part of the first corner portion. The imaginary line extends in the magnetization direction of the permanent magnet through the center of the permanent magnet. Between the first side surface of the permanent magnet and the inner surface of the corresponding slot, there are formed a first gap, a second gap and an abutment area from the first corner portion side in this order. The first gap has a smaller width than the second gap in a direction perpendicular to the first side surface.

摘要： When a corner part that is most distant from a perimeter surface of a rotor core is defined as a first corner part and a corner part in a position that faces the first corner part in a magnetization direction of a permanent magnet is defined as a second corner part, a gap is formed between the second corner part and an inner circumference side of a slot, and the inner circumference side of the slot that forms the gap has an arc surface that has a point X as a center on the inner circumference side of the slot that faces the first corner part. Therefore, the demagnetizing field by the magnetic flux from the stator side does not act intensively on the second corner part of the permanent magnet, and the demagnetizing field instead affects in a wide range of the permanent magnet equally.
