    摘要： A motor generator and an automobile carrying the motor generator. In the motor generator, a yoke part (20) comprises a projected part projected from the axial end face of a tooth (10) to the axial outside in a stator core (100) formed of a pressed powder magnetic substance. The tooth (10) is so formed that its axial length is gradually decreased toward the radial outside of the stator core (100) and its circumferential length is gradually increased toward the radial outside of the stator core (100). The stator core (100) is so formed that a height difference between the axial end face of the yoke part (20) and the axial end face of the tooth (10) is roughly equal to the axial length of a coil end part in any cross section perpendicular to the radial direction of the stator core. Also, the cross sectional area of the tooth (10) in a direction vertical to the radial direction is approximately constant toward the radial outside, and the cross sectional area is secured at a joining part between the tooth (10) and the yoke part (20). In addition, the half of the cross sectional area can be secured in the circumferential cross section of the yoke part (20).

    摘要： A core (10) comprises a plurality of core split members (11) having yoke portions (22) and tooth portions (21) and arranged in such a circumferential shape that the yoke portions (22) contact with each other while the tooth portions (21) being directed inward. The core (10) further comprises a ring (12) contacting with the yoke portions (22), and stoppers (13) mounted on the outer face sides of the yoke portions (22) for fixing the ring (12) on the yoke portions (22). The yoke portions (22) and the ring (12) are formed in corrugated shape to mesh with each other, and the stoppers (13) are formed with projections that engage with the inner side of the ring (12). This structure provides both the rotating electrical machine core having the core split members arranged in the circumferential shape and fastened to each other while preventing occurrence of a stress and a positional displacement between the core split members, and a rotating electrical machine.
