    摘要: A rotating electrical machine includes: a stator core; a stator winding; and a rotor. Cross conductors connect slot conductors to run astride slots with the slot pitch N+1 at coil ends on one side and run astride slots with the slot pitch N−1 at coil ends on another side, with N representing a number of slots per pole; the stator winding includes slot conductor groups each having a plurality of slot conductors; the plurality of slot conductors in each slot conductor group are inserted at a predetermined number Ns of successive slots so that the slot conductors in the slot conductor group take successive slot positions and successive layer positions; and the number Ns is set so that Ns=NSPP+NL when NSPP represents a number of slots per phase per pole and a number of layers is expressed as 2×NL.

    摘要: A rotor comprising: a rotating shaft with at least one keyway formed at an outer circumferential surface thereof and ranging along an axial direction; and a rotor core that includes a key that projects out on an inner circumferential side thereof, and is fitted in the keyway; wherein: a recessed portion that widens outward along a radial direction is formed at each of two sides of the key facing opposite each other along a circumferential direction at the rotor core; a planar portion is formed at a bottom area of the recessed portion so as to lessen stress occurring on each of the two sides of the key facing opposite each other along the circumferential direction; the planar portion is a straight contoured portion extending over a predetermined length along a direction perpendicular to a direction in which the key projects out, and a connecting side surface extending to an inner circumference of the rotor core is formed continuously to an end of the straight contoured portion located on a side opposite from a key side where a key is present; a first corner portion, connecting a side surface of the key with a key-side end of the straight contoured portion, is formed as a circular arc contoured portion; a second corner portion, connecting the end of the straight contoured portion, located on the side opposite from the key side, with the connecting side surface, is formed as a circular arc contoured portion; and dimensions and shapes of various portions are determined so as to substantially equalize stress levels in the first corner portion and in the second corner portion.
