コイル端。 A spider 4 is fitted to the rotating shaft 2, a rotor core 5 is fitted to the spider 4, and both ends of the spider 4 are tightened and fixed by a clamper/coil end support 11 consisting of an annular cylindrical part with an L-shaped cross section. The straight part 9A of the coil is inserted into the slot of the rotor core 5, and the inner peripheral surface of the coil end 9B with respect to the rotating shaft 2 is brought into contact with the outer peripheral surface of the cylindrical part of the clamper/coil end support 11, and the other end The outer circumferential surface side is tightened and fixed by a coil end tightening bind 12, and ventilation holes 11b and 11c are provided in the cylindrical portion of the clamper/coil end support 11 to communicate between the inner circumferential surface and the outer circumferential surface. In a cylindrical rotor provided with a windstop plate 13 that annularly closes both the cylindrical open end of the coil end support 11 and the end face of the spider 4,
The coil end tightening bind 12 is divided and the outer circumferential portions of the gaps 14a, 14b, and 14c at the coil ends are removed, and only the outer circumferential portion of the portion where the coil is located is tightened and fixed, and the wire is passed through the space of the spider 4. A cylindrical rotating electric machine characterized in that the cooling air flowing into the gap between the ends of the coil through the ventilation holes 11b and 11c directly flows out toward the outer circumference without taking a detour to other parts. Rotor coil end.
