  • Publication number: 20230291291
    Abstract: A coil alignment device includes: a plate-shaped first jig having a plurality of grooves arranged along a circumferential direction so as to extend toward a radial-direction outer side; and a second jig that can contact with a segment coil inserted in the first jig. Each groove includes a storage portion extending along a radial direction and having a first length so that leg portions of the segment coils can be stored side by side in the radial direction, and a guiding portion extending from the storage portion toward the radial-direction outer side, and has a first shape so that, using, as a fulcrum, one leg portion inserted in the storage portion, the other leg portion is movable toward the storage portion. The second jig is movable to press the segment coil from a radial-direction side and store the other leg portion into the storage portion.

  • Publication number: 20230129627
    Abstract: A manufacturing method for a laminated core of a rotating electric machine includes a laminating step and a core separating step. In the laminating step, a plurality of core elements are laminated, thereby forming an element laminate. In the core separating step, under a state in which the element laminate is pressed in a lamination direction of the plurality of core elements, a part of the element laminate is moved from the element laminate in a direction orthogonal to the lamination direction by a set dimension in the lamination direction, thereby obtaining a separated laminate.

  • Patent number: 10056799
    Abstract: A coil group 23G is composed of windings 23U to 23W for U phase, V phase, and W phase. One ends 23U1 to 23W1 of the windings for the respective phases composing the coil group 23G are connected to respective power supply bus bars 25U to 25W, and the other ends 23U2 and 23W2 of the windings for the phases positioned at both ends in the circumferential direction in the coil group 23G extend toward the other end 23V2 of the winding for the rest of the phases, whereby the other ends 23U2 to 23W2 of the windings for the respective phases are mutually connected.
