    摘要: To provide a rotary electric machine which is improved in cooling performance. The rotary electric machine includes a rotor; and a stator which, being disposed opposite the rotor, has a stator core having a plurality of slots therein and a stator winding wound in the plurality of slots, wherein the stator has a plurality of coil ends which are formed protruding from an axial end face of the stator core and between adjacent ones of which is provided a radial clearance passing through from the inner diameter side to the outer diameter side, and wherein the stator includes a bus bar which, being disposed on the inner diameter side of the plurality of coil ends so as to occlude the clearances between the plurality of coil ends, guides a refrigerant, which is supplied from the radial direction of the stator, to the plurality of coil ends.

    摘要: A rotating electrical machine can increase the strength of divided cores and, in addition, can achieve both a reduction in iron loss and a high rigidity of the divided cores. The stator of the rotating electrical machine includes a stator core having radially divided cores arranged in a ring, each divided core being a laminate of magnetic steel sheets. Each divided core has a swaged portion in which the laminated magnetic steel sheets are bonded by swaging. The swaged portion is disposed in a core back portion, which is in contact with core back portions of divided cores located on both sides of the divided core at a position whose distance from an outer periphery of the core back portion is within ⅓ of a radial length of the core back portion.

    摘要: Phase windings are configured radially inside first coil ends by connecting together tip portions of first terminals that are bent so as to extend outward from slots that are six slots apart, and radially outside the first coil ends by connecting together tip portions of second terminals that are bent so as to extend outward from slots that are five slots apart, and also connecting together tip portions of second terminals that are bent so as to extend outward from slots that are seven slots apart in modified positions of an inserted slot group, and by connecting together tip portions of second terminals that are bent so as to extend outward from slots that are six slots apart in regions other than the modified positions of the inserted slot group.
